Embodiment Construction
[0023] According to the capacity and discharge current requirements of the storage battery, the present invention consists of one or more constant current discharge modules connected in parallel, and each discharge module is connected by a communication line. The principle block diagram is as follows figure 1 shown. The battery is connected to the input switch of each discharge module, and each discharge module controls the input quantity of its own resistance bar switching switch and adjusts the current supply to the DC converter to adjust the discharge current of the battery according to the data and instructions sent by the main discharge module , for discharge operation.
[0024] figure 2 A block diagram of a single discharge module is given. Each discharge module is mainly composed of an input switch, a discharge voltage and discharge current detection circuit, a microprocessor, a plurality of switching switches, a DC converter, a plurality of PTC thermistor strips and...
