What's the difference between fast charging and slow charging of trams?

The difference between fast charging and slow charging of pure trams is as follows:

1, charging time: fast charging for half an hour, 80%, slow charging for 6~8 hours.

2. Impact on the battery: Fast charging will damage the battery to a certain extent, while slow charging will improve the battery life.

3. Charging method: fast charging is directly connected to the car battery, and there is no need for car charger conversion, while slow charging requires charger conversion.

4. Advantages and disadvantages:

Advantages: DC charging is used for fast charging, which puts forward higher requirements for voltage resistance and protection of power battery pack. Slow charging can not only reduce heat and battery pressure, but also benefit the long-term health of the battery.

Disadvantages: the installation requirements and cost of fast charging equipment are very high, and the current and voltage of fast charging are high, which is easy to make the active material of the battery fall off and the battery heats up, which affects the service life of the battery. The slow charging time is long, which only meets the needs of vehicles running during the day and resting at night.

The difference between fast charging and slow charging of electric vehicles;

1, charging time: fast charging for half an hour, 80%, slow charging for 6~8 hours.

2. Impact on the battery: Fast charging will do some damage to the battery, while slow charging will make the battery life better.

3. Charging method: fast charging is directly connected to the car battery, and there is no need for car charger conversion, while slow charging requires charger conversion.
