OCPP EV Charging Solutions

Why is it said that the charging efficiency of EV is the time required to reach 80% capacity, not full?

Let’s analyze it from the following aspects:

1. Power = Voltage * Current

2. Constant Voltage charging & Constant Current charging

3. Optimal charging curve. The on-board BMS system will communicate with the EV Charger based on information such as battery status/ temperature/ current capacity, and maintain the most suitable power for charging in the most suitable way.


4. How to charge an EV in the healthiest way? Do not fully load, slow charging is the main method, and fast charging is supplemented. Please keep the battery at 20%~30% when parked for a long time, it is best to charge slowly every 3 months, and then discharge to 20%~30%.
