1.具备相关网络与BMS通信的功能，判断充电机是否与电动汽车正确连接；获得电池系统参数、及充电前和充电过程中整组和单体电池的实时数据。依据电池管理系统（BMS）提供的数据，动态调节充电电流或电压参数，执行相应的动作，完成智能充电过程。

2.允许带载开机功能。

3.具有致命错误（如负载极性接反、输入输出短路）停机保护，一般错误报警功能。

4.具有过压、欠压、过流、过热、反接、对地短路、输出反堵二极管失效隔离等保护等相应的报警和保护功能。

5.充电机与BMS通讯进行充电控制过程中，如果BMS发生误报，发送报文电压值与实测电压值不一致时则认为异常，充电机停止充电。

6.触摸屏显示充电机状态和显示充电时故障代码。

7.采用高频开关技术，使得充电机效率高，体积小，重量轻。

8.充电机高频开关充电模块风扇由温度及电流联合控制，当电流小于设定值，散热器温度低于设定值时，风扇不转动。当电流大于设定值，散热器温度高于设定值时，风机开始转动。可以减少噪音和延长风扇寿命。

       30kW portable DC charger has the ability to safely and automatically charge the power battery of an EV. According to the data provided by the battery management system (BMS), the charger dynamically adjusts the charging currentor voltage parameters, performs corresponding actions, and completes the intelligentcharging process.

1. According to the communication withBMS, judge whether the charger is properly connected to the EV; the batterysystem parameters and the real-time data of the whole battery group and singlebattery before and during charging are obtained. According to the data provided by the battery management system (BMS), the charging current or voltage parameters can be dynamically adjusted, and corresponding actions can be performed to complete the intelligent charging process.

2. Power-on function is allowed.

3. Fatal error (such as load polarity reversal, input/output short circuit) shutdown protection, general error alarm function.

4. It has the corresponding alarm and protection functions such as overvoltage, undervoltage, overcurrent, overheat,back connection, short-circuit to the ground, output anti-blocking diode failure isolation and other protection functions.

5. In the process of charging control through communication between the charger and BMS, if the BMS gives false alarm and the voltage value of the sent message is inconsistent with the measured voltage value, it will be considered abnormal and the charger will stop charging.

6. The digital tube displays the state of the charger and the fault code during charging.

7. High frequency switching technology makes the charger high efficiency, small size and light weight.

8. The charging module fan is controlled by temperature and current. When the current is less than the set value, it is scattered. When the heater temperature is lower than the set value, the fan does not turn. When the current exceeds the set value, the radiator temperature s higher than the set value when the fan starts to rotate. Reduces noise and extends fan life.
