The Difference Between Slow Charging and Fast Charging for New Energy Vehicles
1 Answers
New energy vehicles have two types of charging methods: fast charging and slow charging. The differences are as follows: 1. Generally, electric vehicles have two charging ports. There are two charging modes: DC (direct current) charging mode and AC (alternating current) charging mode. In fact, DC and AC charging modes are commonly referred to as fast charging and slow charging, respectively. The fast charging port has five holes, while the slow charging port has seven holes. Some vehicles have their charging ports integrated together, while others have one at the front and one at the rear. 2. There are two charging modes: constant voltage and constant current. Typically, the charging process starts with constant current followed by constant voltage, which improves charging efficiency. Fast charging is quicker due to the difference in charging voltage and current—the higher the current, the faster the charging. When the battery is nearly full, it switches to constant voltage to prevent overcharging and protect the battery.
