The difference between fast charging and slow charging of cars
The main difference between fast charging and slow charging in cars is the charging speed and charging method. Fast charging usually uses direct current, with a high output voltage (50-750V+), a charging power greater than 35kW, and can charge the vehicle 30-80% of its capacity in 1 hour. This fast charging method is suitable for emergency situations or situations where power needs to be replenished quickly. However, due to the high charging power, long-term use of fast charging may cause certain damage to the battery. Slow charging uses alternating current, with an output rated voltage of 220V and a charging power between 7-14kW. It may take several hours or even longer to fully charge an electric car. The advantage of slow charging is that it has less impact on the battery and is suitable for daily use and long-term charging. However, due to its lower charging speed, slow charging may not be suitable for situations where full charging is required in a short time. In general, the difference between fast charging and slow charging in cars is mainly reflected in the charging speed, charging method and applicable scenarios. Users can choose the appropriate charging method according to their needs and actual conditions.
