what is ev charger

What is ev charger? An ev charger, often referred to as a charger or charging pile, is a charging device that provides electric energy for electric vehicles.

The function of an ev charger is similar to that of a gas dispenser in a gas station. It can be fixed on the ground or wall and installed in parking lots or charging stations in public buildings (such as shopping malls, public parking lots) and residential areas.

The input end of the ev charger is directly connected to the AC power grid, while the output end is equipped with a charging plug for charging the electric vehicle. It usually provides two charging methods: regular charging and fast charging. Users can use a specific charging card to swipe the card on the interactive interface provided by the electric vehicle charger to select the charging method, charging time and cost. The display screen of the electric vehicle charger also It can display data such as charging capacity, cost and charging time.

1. Conventional charging of ev charger

Conventional charging of electric vehicle chargers is the ordinary charging we commonly use, also known as slow charging. The charging current is low and the general charging time is 5 to 8 hours. Its advantages are: the charger and installation costs are relatively low, and it can improve charging efficiency and extend the charging time. Battery life.

Because conventional charging charges batteries at a relatively low current, it can be done at home, in parking lots, and at public charging stations; conventional charging stations are generally large enough to charge multiple electric vehicles at the same time.

2. Electric vehicle charger fast charging

Electric vehicle charger fast charging, also known as fast charging, uses a relatively large current to provide short-term charging services for electric vehicles within 20 minutes to 2 hours when they are parked. The general charging current is 150 to 400A.

The advantages of the fast charging mode are: the charging time is short, 70% to 80% of the electricity can be charged in half an hour; since charging can make the battery storage reach 80% to 90% in a short time, corresponding work and installation are required. The cost is higher; due to the use of fast charging, the charging current is large, which puts forward higher requirements for charging technology methods and charging safety. At the same time, the metering and charging design also needs special consideration.
