Now many people are slowly accepting new energy electric vehicles, but they are still a little confused about the car charging piles that are equipped with electric vehicles, especially how to distinguish between DC electric vehicle charging piles and AC electric vehicle charging piles on the market today, Give you a detailed answer here. 1. DC electric vehicle charging pile DC electric vehicle charging pile is commonly known as“fast charge”, it is a power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid to provide DC power for the power battery of the off-vehicle electric vehicle. The input voltage of the DC charging pile adopts three-phase four-wire AC380V±15%, the frequency is 50Hz, and the output is adjustable direct current, which can directly charge the power battery of the electric vehicle. Since the DC charging pile is powered by a three-phase four-wire system, it can provide sufficient power, and the output voltage and current can be adjusted in a large range, which can meet the requirements of fast charging. DC charging pile technical requirements: 1. Charging pile power input voltage: three-phase four-wire 380VAC±15%, frequency 50Hz±5%; 2. The charging pile adopts forced air cooling; 3. The output of the charging pile is DC, and the output voltage meets the battery standard requirements of the charging object; 4. The large output current meets the charging requirements of the battery standard 1C of the charging object, and is backward compatible ;5. The communication interface of the charging pile adopts the CAN communication interface, and the communication protocol is implemented in accordance with the provisions of the communication protocol (provisional) between the GB electric vehicle battery management system and the non-vehicle charger (the charging object is a lithium battery electric vehicle); 2. Communication Electric vehicle charging pile AC electric vehicle charging pile is commonly known as“slow charge”A power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid to provide AC power for the on-board charger of the electric vehicle (that is, the charger fixedly installed on the electric vehicle). The AC charging pile only provides power output and has no charging function. It needs to be connected to the on-board charger to charge the electric vehicle. It is equivalent to just playing a role in controlling the power supply. AC charging pile technical requirements: 1. Charging pile power supply input voltage: single-phase 220VAC±15%, frequency 50Hz±2Hz; 2. The output of the charging pile is AC, and the output voltage meets the battery system requirements of the charging object. 3. The protection of low-voltage power distribution equipment and lines should meet the relevant regulations in the "Low-Voltage Power Distribution Design Code" (GB/50053); 4. The AC charging pile operates continuously at the rated load for a long time, and the temperature rise of the internal heating components and parts should not exceed the requirements in Table 2 of Q/GDW 397-2009; simply speaking, the DC charging pile is a three-phase 380V high-voltage DC fast charge, The AC charging pile is a single-phase 220V low-voltage AC slow charging. In today's market, the price of DC charging piles for car charging piles is obviously higher than that of AC charging piles, because the production cost of DC power supplies will be a little more expensive. There are currently three shell forms for electric vehicle charging piles: wall-mounted electric vehicle charging piles, floor-mounted electric vehicle charging piles, and handheld electric vehicle charging piles.
