According to the intelligent emergency starting power supply, the working temperature range of a battery module is-30 DEG C to 70 DEG C, the working temperature range is wide, the low-temperature performance is good, and the problem that electricity cannot be discharged at low temperature is solved. A battery management system (BMS) monitors and displays the state of a battery module in real time, guides a user to use the battery module in a standard mode and avoids battery abuse, a charging interface and a discharging interface are different to control charging and discharging separately, physical fool-proof of the charging and discharging interface can be achieved, connection errors of the user are avoided, reverse current control is added to the battery discharging interface, and the battery charging and discharging efficiency is improved. The vehicle can be prevented from reversely charging the low-voltage power supply. When a fault occurs, a user can be quickly reminded to pay attention through audible and visual alarm; the display screen displays the state of the battery in real time, including fault type, residual electric quantity, voltage and other information. And the battery management system BMS and the fuse perform dual short-circuit protection, so that the power supply is higher in safety and better in reliability.
本发明公开了一种智能化应急启动电源,电池模块的工作温度范围是‑30℃‑70℃,工作温度宽,低温性能好,解决低温放不出电的问题。电池管理系统BMS实时监测并显示电池模块状态,引导用户规范使用,避免电池滥用,并且充电接口和放电接口采用异口将充电和放电分开控制,能够实现充放电接口的物理防呆,避免用户连接错误,并且电池放电接口增加有反向电流控制,能够防止车辆向低压电源反向充电。当出现故障时,通过声光告警可以快速提醒用户注意;显示屏实时显示电池状态,包含故障类型、剩余电量、电压等信息。电池管理系统BMS和熔断器双重短路保护,电源安全性更高,可靠性更好。
