What are the introduction and main features of the communication charging pile charger?

The high-power charger of the AC charging pile is a high-power charger specially designed for medium and large pure electric vehicles. It can be charged in mobile mode or installed on the vehicle; the electric vehicle charger can communicate with the battery management system and receive power from the battery. The management system receives battery data. During the charging process, take appropriate measures to ensure that the voltage of a single battery in a group of batteries does not exceed the upper limit. At the same time, when the battery management system sends a serious battery failure message, it can automatically stop charging.

The AC charging pile has panel operation and remote operation functions. The charger is connected to the charger monitoring system through the CAN bus. In addition to shutting down and cutting off the input power, all functions can be completed on the monitoring computer. The charger has a fault alarm function, which can automatically send fault information to the monitoring system. Electric vehicle chargers have protection functions such as input undervoltage, input overvoltage, output short circuit, battery reverse connection, output overvoltage, overheating, and battery failure.

The main features of the communication charging pile charger:

1. The switching power supply control chip is imported military-grade IC, the charger principle planning is optimized and reasonable, and the production process is strictly perfect to ensure the safe operation of the machine.

2. The power switch tube adopts Nissan (IGBT) equipment to improve the reliability and operation stability of the whole machine.

3. The digital meter displays the charging voltage and current.

4. Timing function: manual timing charging mode can be selected (optional).

5. Charging characteristics: use constant current technology, constant current at the initial stage of charging, so that each battery can be fully charged quickly, the charging power is high, and the temperature rise of the AC charging pile battery is low; when the charging voltage reaches the upper limit voltage, it will automatically switch to constant voltage and current limiting Charging effectively improves the capacity conversion efficiency of the battery; trickle floating charging enables each single battery to receive power evenly to ensure battery capacity. It can recover to a large extent, effectively solve the problem of unbalanced monomer voltage, avoid the risk of overvoltage charging caused by the change of mains voltage and the completion of battery charging, and greatly extend the service life of the battery.

Communication charging pile: The power battery is charged by a low-power, slow-charging, and low-cost on-board charger, commonly known as "slow charging". The AC charging pile connects the charging socket to the vehicle charger to charge the power battery.

The input voltage of the communication charging pile is 220V, the charging power is generally 7kw, and it takes 8-15 hours to fully charge. It is mainly used for private charging piles in the community. The manufacturing and installation cost of the AC charging pile is only 800-1200 yuan per pile (excluding line modification and capacity expansion), and the structure is simple, the volume is small, it can be hung on the wall, and it is portable and can be carried directly in the car.
