How to charge electric vehicles?

2022-11-15 226

There are three ways to charge electric vehicles, namely public charging piles, home charging piles and portable charging guns.

I. Public charging pile

1. Park the vehicle in the charging space, put it in P gear and open the charging port of the vehicle.

2. Unplug the charging gun from the charging post and insert it into the charging port of the vehicle.

3. According to the requirements and steps of each charging post, just click to start charging.


II. Home Charging Stands

1. Ensure that the vehicle is in park and open the charging port cover.

2. Unplug the charging gun from the charging post and insert it into the charging port of the vehicle.

3. Confirm whether the vehicle is charging properly by observing the charging post and the indicator light status on the charging port, most of the home charging posts currently support plug-and-charge, but there are a few home charging posts that require the use of mobile phone APP or other means to start charging.


Portable charging gun

1. Park the car and open the AC charging port.

2. Plug the plug end of the charging gun into the three-hole socket and the tip end into the AC charging port.

3. Confirm whether the vehicle is charging properly by observing the indicator lights on the charging gun and charging port or checking the charging information on the vehicle screen.

The best way to charge a new energy vehicle is to charge it in time before the power falls below 20% and to stop charging the battery when it reaches 80%-90%, as overcharging or over-discharging the battery will lead to a drop in its overall performance and directly affect the vehicle's range.


It is advisable to use a home charger if one is fitted, as it is more convenient and cheaper than a public charger, and the charging speed is much faster than a portable charging gun.

If you are in a hurry, it is recommended to use public charging piles. Some DC fast charging piles have a maximum power of 200kw or more, and most new energy vehicles can be charged to 50% in half an hour using fast charging.


The difference between DC and AC charging posts

DC charging piles: DC electric vehicle charging stations, commonly known as "fast chargers", are fixed on the outside of electric vehicles and are connected to the AC grid. It is a power supply device that provides DC power to the power battery of the non-vehicle electric vehicle. The DC charging post uses a three-phase four-wire AC 380V±15% input voltage, 50Hz frequency and an adjustable DC output to directly charge the electric vehicle's power battery. As the DC charging pile adopts three-phase four-wire power supply, it can provide sufficient power with a wide range of output voltage and current adjustment, which can meet the requirements of fast charging.

AC charging post: AC electric vehicle charging post, commonly known as a "slow charger", is fixed to the exterior of the electric vehicle and connected to the AC grid. ) A power supply device that provides AC power. The AC charging post only provides power output and has no charging function. It needs to be connected to an on-board charger to charge the electric vehicle. It is equivalent to just acting as a control power supply.

Difference between the two: In simple terms, an AC charging post requires the aid of an on-board charger for charging, whereas a DC fast charging post does not require this device. The difference in charging speed between the two is significant. A pure electric vehicle (normal battery capacity) takes 8 hours to fully charge via an AC charging post, whereas it only takes 2-3 hours via a DC fast charging post. The AC charging post provides the electrical input to the charger of the electric vehicle. Due to the low power of the on-board charger, fast charging is not possible.
