Embodiment Construction

[0017] to combine figure 1 , figure 2 , image 3 , Figure 4 The present invention is described in detail:

[0018] The positive output of the battery power supply of the present invention is connected to 3 main circuit protectors to provide an overcurrent protection for the entire control system. On the one hand, connect and control the 5 main circuit protectors, and then connect the electric lock switch, handbrake switch, and reversing switch. Switching, one output of the control circuit is connected to 5 shunts, the signal of the shunt is amplified and shaped by the internal circuit to drive the car instrument, the accelerator accelerator 8 The accelerator accelerator converts the angle signal of the accelerator pedal into a voltage signal by using the magnetoelectric effect of the Hall element, The control circuit collects the signal, and converts it into an adjustable duty ratio waveform signal through the pulse width modulation circuit of the controller, and the sig...

Abstract

The invention relates to a controller for a direct current motor of a pure electric vehicle. The controller consists of a wave chopper 1, a main contactor 2, a reversing contactor 3, a main circuit protector 4, a control circuit protector 5, a shunt 6, a heat-dissipation aluminum plate 7 and an accelerator 8. The controller has the advantages that the reset function can be used repeatedly, and the wire harness protection function is strong; moreover, the controller does not need to be replaced or maintained, is low in efficiency cost and can effectively ensure the reliability and the safety of protected wire harnesses.
