EV Charger

• Get to know EV car

EV (Electric Vehicle) is the term for electric vehicles or simply referred to as “electric cars” where energy can come from multiple sources, whether stored in batteries or built from a generator and converts energy from batteries to use to drive. Which can be divided into 2 main types:

1. Battery Electric Vehicles (BEVs)

These cars are 100% battery powered without internal combustion engines. So it has a large battery and can run a long distance on a single charge. The distance to drive will depend on the size of the battery and other environmental factors.

2. Plug-In Hybrid Electric Vehicles (PHEVs)

These cars have a combined fuel and electrical system. It can be plugged into the charger to store charge in the battery as needed. And it can run farther than hybrid vehicles (HEVs).

• Advantages that distinguish EV cars from general cars

1. More economical

If you try to calculate the cost rate regular cars have an average cost of 2-3 Baht per kilometer of gas, while the cost of electricity per kilometer is only 0.5-1 Baht.

2. Help save the environment

Because EV cars do not have to use combustion engines while working, causing no exhaust to be emitted. Therefore, it does not pollute the world and it is environmental friendly.

3. No noise

A typical car has a sound intensity of less than 65 dB, but an electric vehicle has a sound intensity that is less than 35 dB or is only as loud as a whisper.

EV Charger

• EV components

1. Motor

In EV cars there is a motor for driving which will depend on the size and the desired performance. The motor power is between 15 kW. – 200 kW.

2. Battery pack

It is responsible for storing and supplying power to the motor. The battery will charge while the vehicle slows down or while connected to the charging station. The capacity of the battery pack ranges from 5 kWh. – 100 kWh. at a voltage of 300 VAC. – 500 VAC.

3. Charging System (On-Board Charger)

The charging system is responsible for converting AC electricity to DC electricity. It has a control system and limits the amount of current flow, not exceeding the maximum value of the charging cable or not to exceed the value that the charging system can accept.

4. Socket for charging

For EV car charger sockets can be divided into 2 types depending on the type of charging as follow:

4.1. Normal Charge or AC Charge

For normal charging that is connected to the electric power in the building or home. Which the charging time will be reduced to about 4-7 hours. The charger use will be divided into 2 types:
– Type 1: It is a charger for EV vehicles in the United States and Japan.
– Type 2: It is the most popular charger for EV cars in Europe.

4.2. Fast Charge / Quick Charge or DC Charge

For charging directly connected to a DC power supply for vehicles that support charging in a power station only. In which the charging head used is divided into 3 types:
– CHAdeMO: It is widely used in Japan.
– GB/T : China was developed for domestic use.
– CCS : It is a charger that is divided into 2 sub-types:

The first type is the CCS Type 1 charger: it is a charger used for cars in the United States. The charger is smaller than CCS Type 2 and supports a voltage of 200 V. – 500 V.
Another type is CCS Type 2 charger: it is a charger that is commonly used in Europe. This type of charger is larger and has more power than the CCS Type 1 charger.

• EV Charger included with an EV vehicle may be unsafe

Usually, when we buy an EV car, an electric charging cable is included. It is use with the car. But the device that is included is an Emergency Charger (Mode 2 cable) that does not have a separate electrical circuit. And it does not have a standard voltage regulating system, so it’s ideal for temporary charging for a short time because it’s not designed to be plugged in overnight. Once fully charged, you should unplug it immediately because electric car charger supplied with no power cut system when the battery is fully charged, it is causing heat to accumulate which can damage the car body and home electrical system.

• Which EV charger is safe and quality?

Things to keep in mind when choosing the electric car charger is an On-Board Charger, because the size of the On-Board Charger will limit the amount of current flow not exceeding the maximum value of the charger or charging system can accept. Therefore, the power of the charger should be close to the size of the On-Board Charger. For example, one brand of car has an On-Board charger size of 3.6 kW. car charger that is similar to 3.6 kW.

Electric car charger that has a charging system with protection system (Mode 3 cable) is an EV Charger with a dedicated plug for high safety. There is an electrical circuit independent from the household electrical system. There are important protection systems such as over-current protection, over-temperature protection, grounding and power cut-off. It helps you to not worry about charging your car overnight. It can be charged at full capacity of each vehicle. It also has a control system and cuts off the power when the battery is fully charged. Eliminating the need to disconnect the charger. Therefore, not as complicated as using the included electric car charger.

One more advantage electric car charger included with the car is a key locking system that prevents theft, charging cable and prevents unauthorized use. Including having a safe energy management system. You can select the charging time to save costs during times of high power demand. And you can limit the current to protect the over load. Most importantly, it has passed IEC 62196, IEC 61851 and CE standards.

• How to use the EV Charger as safe as possible?

You have already known that which one to choose for electric car charger. How to be safe and up to standard. The next important thing to understand is its usability. Electric car charger correctly. Many people would wonder when an EV vehicle is driven by an electric motor and when charging the car, will it be the same as plugging in common electrical appliances in the house? Is it dangerous to charge at home? And need to use an accessories or not? Then, we will find out which charging will be the most accurate and safe. Initially, EV charging can be done in a variety of ways. Depending on the application, the equipment available including the electrical system. Either electricity within the house or at different buildings, which can be divided into 4 types as follow:

1. MODE 1: AC to DC cable corresponding to the home power supply

Electric car charger, this type of battery can be recharged directly through standard electrical outlets in general residences. Conventional without protection system can deliver a maximum current of 11 A. which is low. It takes a long time to charge the battery. In addition, drawing high power from the charger will cause the cable to accumulate more and more heat, and if overloaded or continuously charged for a long time, it can cause a fire.

2. MODE 2: AC to DC cable without protection device

It is a charging system that has a dedicated circuit to charge EV vehicle, but does not have a standard voltage regulation system that the electric vehicle charging cable included. When buying an electric car will be this type of charging. It’s not designed to keep it plugged in all night because there’s no power cut-off when it’s fully charged. It should only be used in times of necessity or for a short period of time, but usually the car owner keeps it plugged in all night, causing the fire to flow all the time. Therefore, there is a chance of danger or causing the car battery to deteriorate faster than it should.

3. MODE 3: Fixed, dedicated circuit-socket

Electric car charger, this type is the safest for charging an EV car at home, which must be charged via as EV Charger. The EV car body is connected to the electrical network directly through a special plug and socket. There is a dedicated circuit that can be charged at 3.7 – 22 kW. equipped with safety protection systems such as over-temperature protection, grounding, over-load protection while charging. It can be added to prevent leakage and surge protection for maximum safety.

4. MODE 4 : DC Connection

All 3 types of EV chargers mentioned above are connected directly to a home or building power supply. Unlike this type 4 system that receives DC power from the charging station through a dedicated plug and not through the car charger system. It can charge up to 50kW. also known as Fast Charge, which this type of charging station will have a high cost and demand for electrical infrastructure.

• How to know, how many hours to charge?

If you know the size of the On-Board Charger and the battery size, you can easily calculate the charging time. Just divide the size of the battery by the size of the On-Board Charger to get the charging time in hours. For example, one brand of car has an On-Board Charger size of 3.6 kW. and a battery size of 20 kWh. It will take 20/3.6 or equal to 5.5 hours to charge. But depending on the percentage of battery remain and the size of the Kw. of the device to charge.
