If you cannot afford to install a charging station at home; if you do not have your own parking space; or you do not have the right to use the ev charging solutions installed in the apartment building, you can choose a public charging station. They are designed to charge your electric vehicle faster with a Level 2 EV charger or a Level 3 EV charger.

Electric car charging station in the parking lot

When the coverage of the charging station is dense, you can find a charging station for your electric car in the parking lot of the shopping mall; restaurant; Or even a hotel. These charging stations are an asset for brands to attract and retain their customers to shop or experience their services.

Electric car charging station on the highway

The final option is the ultra-fast charging stations for electric cars on the highway. The growth of a network of tollgates outside of urban areas has facilitated medium and long-distance trips with tolls. Therefore, the installation of ev charging solutions on highways is an urgent requirement, in parallel with the development of charging stations in urban areas.

Charging at these clean stations, electric cars can recover 80% of the battery in less than 30 minutes, to be able to travel distances up to 150km. However, to charge an electric vehicle with this ultra-fast cleaner, your vehicle must be equipped with a compatible battery. More specifically, the capacity that the car charger can withstand is a key factor for a quick recharge time.

Is it possible to build a charging point at home?

Installing a charging point is a viable idea. A home charging point will allow you to be proactive in charging your electric car and save more time. In addition, the cost of electricity is also lower than charging electric vehicles at public charging stations. Because electricity for business production is charged higher than for domestic electricity.…

Charging culture in public places

Unofficial conventions for charging batteries at public stations that you need to know are:

Only charge 80% of the battery: When you have reached 80% charge, unplug the charger from your car and move it out of the charging compartment so others can use it.

Don’t unplug other people: If you’re at an ev charging solution and find an electric vehicle left in the charging compartment for a long time, ask the charging station staff if they can notify the owner to come and move it go or not.

Some people think it’s okay to unplug a fully charged car, but this is not civilized at all. If you must, leave a note on the windshield of your vehicle, explaining why. However, also remember, that some chargers do not allow you to unplug when the vehicle is locked.

Tidy up the charging cable when you’re done using it: Disposing of charging cables indiscriminately can be dangerous to yourself or those who come after because they can get caught under the vehicle.

EV Quick Charger 2022

Would it be better to choose slow, fast, or super-fast ev charging solutions?

One of the most common questions asked by EV drivers is: Choose slow charging; or fast charging; Or is super fast better? Here is the detailed answer:

Slow charging

They may take a little longer, but slow chargers (EV level 1) are arguably the simplest and most convenient method of charging electric vehicles. Because it takes longer, slow charging is the ideal choice for charging electric vehicles at home, overnight. 

Fast charging

One step ahead of slow charging is the option of fast charging (EV level 2) at public charging stations or in supermarket parking lots; malls; movie theaters… You can also install a fast-charging station at home if you want.

Of course, fast charging will be a lot faster than slow charging. If you are somewhere and intend to leave your electric car parked for a while, it is really an ideal solution to charge the car battery.

Superfast charging

As we mentioned above, super-fast chargers use a high-power DC current to recharge cars in the fastest time possible. It can fully charge an electric car to 80% in just 15 minutes. With the remaining 20%, the charging speed will be reduced to help preserve the battery.

That is, the life of the battery is protected to the maximum, even with heavy use of the battery.

This is what makes them super convenient; reduce range anxiety, and make the idea of ​​owning an electric vehicle much more appealing to users.

It is worth mentioning that they use a huge amount of power – so you will be hard-pressed to install a super-fast ev charging solution at home. Instead, the places you can find them are usually at highway service stations or public stations.


So, is it better to choose slow, fast, or super-fast charging? With the things we have summarized above, super-fast charging is the optimal choice. However, there are 2 problems that it is not compatible with all vehicles and it is not possible to install a home ev charging solution. In the end, the choice of which method to charge an electric car depends on the actual situation.

5 important features to pay attention to when buying an electric car charger

Charging speed

Speed ​​plays a vital role in the ability of commercial chargers to serve electric vehicle drivers and generate revenue. The charging speed or capacity of an EV charger is important for obvious reasons: Users often don’t have a lot of time and want everything done quickly. The type of charger and how it is used will directly determine the speed.

EV chargers have three charging levels respectively: Level 1, 2, and 3. Level 1 chargers use a standard 110v outlet, but charging is very slow and can take almost a day to fully charge. an EV.

Generally, level 3 fast chargers, or DC fast chargers, are EV chargers that are the highest capacity chargers and are often used as range extenders along major travel corridors for long trips to can assist drivers who have long distances.

Level 2 chargers are the standard and most commonly used ev charging solutions for commercial use and account for more than 80% of charging environments in locations such as garages, hotels, train depots, restaurants, hospitals, multi-family or office complexes.

One factor that affects the speed of electric vehicle charging is the power cord. With high-quality chargers, usually, the power cord will be a large fiber size, made of pure copper. The outside uses safe fireproof plastic. Meanwhile, cheap chargers are usually small power cords, easily broken. Therefore, you should choose genuine, high-grade chargers for safe and durable vehicle operation.

Security system

The factor of safety may not be the first criterion that buyers think of, but ultimately, it is one of the most essential attributes for users of EV chargers and the power grid. As with any large appliance, a reliable and secure system is of utmost importance to the safety of its users.

Since Level 2 chargers use a higher voltage than Tier 1 chargers, the National Electrical Code specifies higher safety requirements for Class 2 chargers as well. The safety system in Level 2 chargers must be designed to consistently monitor the vehicle charging. This is to ensure the safety of those around the charger.

Efficient use of electricity

Today’s environmentally conscious users demand energy-efficient devices across all industries and EV chargers are no exception because all commercial chargers come in economizers. different energies.

Level 2 chargers provide about 10% more energy efficiency than Level 1 chargers. The most energy-efficient commercial chargers will receive the ENERGY STAR label, which requires the charger to be energy efficient while charging the vehicle and when not in operation because commercial chargers are in standby mode. about 85% of the time.

Open Protocol Fee Network and Future Protocols

The ev charging solutions network creates a communication environment between charging stations, network owners, and the power grid. They allow charging network owners to charge for usage, limit access, monitor energy, and data usage, and facilitate intelligent charging for more optimal charging.

Closed networks are tied to a specific hardware manufacturer and do not allow inter-network changes, so they cannot be easily upgraded in software or hardware.

The open network allows ev charging solutions to connect to many other open networks with the same hardware. In today’s evolving industry, open networks provide the adaptability and flexibility to switch network providers.

The customizability of ev charging solutions

In addition to being able to accommodate current electric vehicle drivers and prepare them for future growth, commercial chargers can demonstrate a manufacturing company’s commitment to sustainability.

For businesses, commercial chargers are essential to being able to attract and retain tenants/customers, especially since electric vehicle drivers are among the most sought-after.

EV stands for Electric Vehicle. 100% use electrical energy to operate. EVs use a 100% electric motor to drive instead of an internal combustion engine (gasoline, diesel). Electrical energy is stored in the Battery, which can be fully charged many times after it is used up. 

EV means a four-wheeled, electric vehicle! Some places still call electric cars ” Electric cars “. The word is quite long and difficult to read; difficult to write, and easy to be replaced by in-depth keywords: EV. Currently, “electric cars” account for only 1% of the global auto market.


FCV stands for Fuel Cell Vehicle – An electric car that runs on liquefied hydrogen gas (H2, hydrogen). That is, it uses the reaction of Hydrogen with Oxygen to generate electricity; keep the electric motor running. FCV’s battery can store regenerative current when the vehicle is in operation.

FCV is the next generation of EVs, so it has more outstanding advantages. Structure and operating principle are similar to EV cars because it is also electric car.

EV and FCV . vehicle structure

The basic structure of an EV vehicle: Energy battery, driving electric motor, power electronics, and regenerative braking. One of the factors that help EVs operate continuously is the charging station. Depending on the vehicle model, there can be up to 4 electric motors on 4 wheels.

First: Structure of the battery system

The battery system is very important in the EV vehicle structure. It has a relatively large size and is placed under the floor of the car. Lithium-ion batteries used in EV systems: are batteries that can be recharged over and over again. During the charging process, Li ions move from the anode to the cathode; and vice versa during discharge. 

The voltage of an EV vehicle ranges from 400V. Thus, this is also a major drawback of EVs. Because the energy that the battery can store or charge after each charge is quite modest compared to a normal gas tank. What’s more, the time spent on charging is much longer than refueling. This is also an important part of a large price, accounting for one-third of the price of an EV. 

Currently, with modern technical technologies. Manufacturers are focused mainly on improving the battery system. The lithium-ion battery can recharge a large battery and shorten the charging time. 

2nd: Electric motor

Compared to a conventional internal combustion engine, the driver will feel the electric motor of an EV. 

Types of electric motors are commonly used: 3-phase synchronous motor, and 3-phase asynchronous motor. 

The electric motor is very small, compact, and light. Many car manufacturers even equip each electric motor with one wheel. Make the vehicle capable of full-time 4-wheel drive without the need for a differential; make the driver have a very new experience, very real.

ev charging solutions

An electric charging station is a transformer station that converts current to use a universal charger to charge electric energy into the battery. Electric car manufacturers want to develop more shortly; The ev charging solutions are one of the top factors to pay attention to. 

Accordingly, shortly, new technology will allow EV vehicles to quickly charge in 3 minutes and travel 100 km. Thus, charging the battery will be faster or equal to the time it takes to refuel. 

However, experts also warn that fast charging is only used in emergencies. Because fast charging will be one of the main reasons why your electric car battery quickly loses its life. 

Power Electronics

The power electronics system (Power Electronics) is an indispensable system for electric cars. This is the system that helps: Converts the properties of the electric current so that the electric motor works.

There are two power electronic systems: 

An AC/DC converter: AC to DC input at the input, charging the battery. A DC/AC converter at the battery output distributes electrical energy to the electric motor.

Why need 2 power electronic systems:

The current we usually use is AC (alternating current); This is also the current used to distribute to the stator of the electric motor. However, the battery used by electric vehicles can only store DC current and only distribute DC power. 

Therefore, the entire electrical system is designed for electric vehicles in general and EVs in particular; must be based on the capabilities of this power electronic system. 

Fifth: Coordination of transmission

An EV (electric vehicle) powertrain is a combination of the engine, transmission, and other transmission components that form a system that determines the vehicle’s range and performance.

EVs can have 4 electric motors on 4 wheels, so an AI system (Artificial Intelligence) is needed to automatically coordinate this drive to be homogeneous as the vehicle moves. Currently, this technology has matured stably and safely. It can be said that this system helps to automatically balance all transmissions on the vehicle.

Regenerative brake

Regenerative braking is also known as energy recovery braking. This feature helps to recover energy when braking and use it to charge the battery. You won’t be able to recover 100% of this energy, of course; if you go and brake continuously but the battery is still decreasing.

There are also other systems such as: 

Thermal (cooling) system: Helps maintain an appropriate operating temperature range of motors, electric motors, power electronics, and other components.

Transmission (electrical): Transmits mechanical energy from the electric traction motor to drive the wheels. Traction battery pack: Stores electricity for use by electric traction motors. 

The role of batteries in electric vehicle systems

What is an electric car battery?

An electric car battery (also known as a secondary battery) is a rechargeable battery that can repeat a charge cycle by plugging a battery charger into a power source. 

There are two types of electric car batteries commonly used today: 

  • Lithium-ion battery: is a rechargeable battery commonly used on consumer electronic devices such as phones, laptops, etc., and electric vehicles. The advantage of this type of battery is its low self-discharge rate and high energy density, so it is preferred for use in the electric vehicle battery industry.
  • Nickel-metal hydride battery: is a rechargeable battery used in hybrid vehicles. 

Compared with conventional batteries; Electric vehicle batteries are much smaller and can also store more energy.

Role of the electric car battery.

Particularly for electric car models; The battery is an important part because it is a factor that directly affects the performance of the car. In addition, the battery also has a direct impact on the cost and performance of the vehicle.

With today’s great development in battery manufacturing technology; The lifespan of electric car batteries is increasing day by day. If the owner of the car knows how to use it properly, it is possible to extend the average life of the battery from 10 to 12 years.

Factors affecting the battery life of electric cars.

The average electric car battery usually lasts about 8 years; It can even be up to 10 to 12 years depending on the care and use of the car owner. Accordingly, electric car battery life can be affected by many factors:

Weather condition

This is the first factor to mention because climate conditions greatly affect the life of electric car batteries. Battery life can often be maxed out; if maintained in use with an ambient temperature of about 20 degrees Celsius or less; during use.

If electric cars are “exposed to the sun” outdoors for a long time; not carefully covered, the battery of the car is also very easily reduced.

Charging habits

The habit you charge the battery is also one of the reasons that directly affect the life of an electric car battery. 

“The battery of an electric vehicle will have the best life if it is maintained between 20% and 85%. You should only fully charge the battery when there is a need to use the maximum operating distance of the car”.

So, do you charge the battery to 100%? Do you let the battery drain frequently? Please note that this is very easy to make your car battery “dead”.

In addition, there are other familiar children you need to pay attention to; its fast charging function. This is a “threat” that directly affects the quality of car batteries. During fast charging, heat is likely to cause a chemical reaction between the substances inside the battery; causing the components in the battery to charge and lose the ability to store electricity.

Vehicle operating method

The way electric cars are operated is also one of the factors that reduce battery life. Specifically, the life of electric car batteries will be severely reduced if the driver abuses the brake function or accelerates frequently. Therefore, electric cars traveling in urban areas and crowded vehicles will often have a shorter battery life than cars traveling on long and airy roads.

Battery quality

Nowadays, technical technology develops; Electric vehicles such as bicycles, motorbikes, and cars have become a trend. Electric cars are very popular and widely used by many people. Therefore, it is increasingly being upgraded, improved, and met according to the needs.

Like electric cars: the battery life of cars has greatly increased since their inception. If in the past, electric car batteries could only last about 5 years, today; most batteries are upgraded and have a lifespan of 8 to 10 years; maybe even longer.

Maintenance way

Good maintenance is like you going to regular health checkups. The maintenance and care of electric car batteries is also an important factor affecting the life of the car. Once you use, store and replace the battery in the wrong way as recommended by the manufacturer; the battery life of the car will also be very easily shortened.
