The invention discloses a universal low-speed vehicle direct current charger device and system and an implementation method, and relates to a low-speed vehicle charging technology, the battery type of a low-speed vehicle is judged by judging whether a charger receives message information after being connected, after the charger is connected, if the message information is received, it is indicated that a battery system of the vehicle is a lithium battery power supply system, at the moment, the charger judges an output voltage and the output current of the charger by receiving the message information of a battery management module, when the charger is online and overtime and still cannot receive the message information, it is indicated that a battery system of the vehicle is a power supply system with a lead-acid storage battery as a power source, the voltage of a storage battery pack is collected, and the charging demand voltage is judged; the output voltage and the current of the charger are automatically adjusted to charge the storage battery; one machine has multiple purposes, and one machine is universal; use efficiency of equipment is improved, the number of chargers equipped in large factories, supermarkets or other large transfer places is reduced, and equipment investment is reduced.
本发明公开了一种通用低速车直流充电机装置、系统及实现方法,涉及低速车充电技术,通过充电机连接后是否接收到报文信息来判断低速车电池类型,当充电机联机后,如果接收到报文信息,表明该车辆的电池系统为锂电池供电系统,此时充电机通过接收电池管理模块的报文信息来判断充电机的输出电压和输出电流,当充电机联机并超时后,仍然接收不到报文信息,表明该车辆的电池系统为铅酸蓄电池为动力源的供电系统,采集到的蓄电池组电压,判断充电需求电压,自动调节充电机的输出电压和电流,对蓄电池进行充电;实现了一机多用,一机通用;提高了设备的使用效率,减少大型工厂,商超,或其它大型转运场所配备充电机数量,降低设备投入。
