Nowadays, many people drive new energy and green brand cars on the streets. This kind of electric car must be most concerned about its endurance. It will talk about DC charging and AC charging, but this is a blind spot for many people New energy vehicle maintenance Let's talk about the difference between DC charging pile and AC charging pile.

The output voltage and current can be adjusted in a wide range, so it can realize rapid charging of electric vehicles. Taking the DC charging pile 180KW as an example, assuming that the battery capacity on the car is 60kWh (that is, the battery capacity is about 60 kilowatt hours), the charging time of the car is calculated according to the charging time of the car. In addition, considering the charging rate factor of the battery, the charging time is calculated to be about 40 minutes.

AC charging is commonly known as "slow charging". For vehicles, it takes about 6 to 8 hours to fully charge, and the difference between the two is also different on the charging pile. The AC charging pile needs to use the on-board charger to charge the vehicle, while the DC fast charging pile does not need this equipment, and directly charges the corresponding electricity through the charging pile, As the power of on-board charger is not large, it can not realize fast charging.

DC fast charging pile is a power supply device that is fixed outside the electric vehicle and connected to the AC power grid, and can provide DC power for the power battery of the off board electric vehicle. DC charging can provide sufficient power, and the output voltage and current can be adjusted in a wide range, which can meet the requirements of fast charging.

The difference between DC charging pile and AC charging pile has been introduced in detail above. In short, the difference between DC charging and AC charging lies in the time. Secondly, the charging current and voltage are different. The common name of DC charging is "fast charging", which requires a dedicated charging pile. The charging voltage reaches about 380V of three-phase AC power, A power supply device that provides DC power for the power battery of off board electric vehicles.
