Remote storage battery constant-current discharging device

The invention discloses a remote storage battery constant-current discharging device. According to the invention, the discharging duration, the discharging current and the voltage discharging lower limit are controlled, and a battery pack discharging function is achieved through stable and accurate constant-current discharging of the discharging current. In the whole discharging process, fixed-constant-current discharging is carried out according to a set current, the discharging time and the discharging voltage protection lower limit can be set, and discharging is automatically stopped when the set discharging time or the set voltage lower limit is reached. According to the design, in the discharging process, the discharging current, the discharging voltage, the discharging time and the discharging capacity are displayed in real time, and discharging data are automatically stored and are not lost in power failure. The device has the functions of reverse connection, misconnection, overcurrent, undercurrent, o
