1、蓄力电池

1 、 storage battery

充电机没有与动力蓄电池总成建立连接时，充电机经过自检后自动初始化为常规控制充电方式（可选择手动、IC卡或充电机监控系统操作方式）。充电机采用手动操作时，应具有明确的操作指导信息。

When the charger is not connected with the power battery assembly, the charger automatically initializes to the conventional control charging mode after the self-test, and the manual, IC card or charger monitoring system operation mode can be selected. When manual operation is adopted, the charger should have clear operation guidance information.

充电机与动力蓄电池总成建立连接后，通过通信获得动力蓄电池总成的充电信息，自动初始化为动力蓄电池总成ECU自动控制方式（简称自动控制充电方式）。

Charger and battery assembly connection, charging battery assembly information obtained through communication, automatic initialization for power battery assembly ECU automatic control mode (automatic control charging).

2、充电机接口

2. Charger interface

充电机与电动汽车之间的连接应包括以下几部分：高压充电线路、充电控制导引线、充电控制电源线、充电监控通信连接线、接地保护线。同时，充电机应预留与充电站监控系统连接的通信接口。

The connection between charger and electric vehicle should include the following parts: high voltage charging line, charging control lead wire, charging control power line, charging monitoring communication connection line, grounding protection line. At the same time, the charger should reserve the communication interface connected with the charging station monitoring system.

3、充电机通信要求

3. Communication requirements of charger

在这方面一般通过CAN总线以及CAN2.0协议作为充电机的通信总线形式和通信协议。

In this regard, the CAN bus and the CAN2.0 protocol are used as the communication bus and communication protocol of the charger.

4、通信内容包括

4. The contents of communication include

动力蓄电池单体、模块和总成的相关技术参数，充电过程中电池的状态参数，充电机工作状态参数，车辆基本信息等。

The related technical parameters of the power battery monomer, module and assembly, the state parameters of the battery in the charging process, the working state parameters of the charger, the basic information of the vehicle, etc..

5、充电机的充电效率和功率因数

5. Charging efficiency and power factor of charger

交流输入隔离型AC-DC充电机的输出电压为额定电压的50%～100%，并且输出电流为额定电流时，功率因数应大于0.85，效率应大于等于90%。直流输入非隔离型DC-DC充电机的效率待定。

AC input isolated AC-DC charger output voltage is rated voltage of 50% ~ 100%, and the output current is rated current, power factor should be greater than 0.85, the efficiency should be greater than or equal to 90%. The efficiency of DC input non isolated DC-DC charger is undetermined.

充电桩可广泛应用于公共停车场、大型购物中心、社会车库等区域，为电动汽车提供安全、快速、便捷的充电服务。家用的简易充电桩功能也并不少于公共用充电桩，使用便捷，可与智能家居系统形成系统集成，可实时监控充电状态。

Charging piles can be widely used in public parking lots, shopping malls, social garages and other areas, providing safe, fast and convenient charging service for electric vehicles. The function of simple charging pile is not less than that of public charging pile. It is easy to use and can form system integration with smart home system. It can monitor the charging status in real time.
