Problems solved by technology
[0005] (1) Isolated DC / DC power supply modules rarely have automotive-grade products; (2) Isolated DC / DC power supply modules are difficult to achieve sleep and wake-up; (3) The static power consumption of isolated DC / DC power supply modules is too large: (4) ), high cost; (5), although the isolated DC / DC module is used, it is difficult to achieve the isolation effect due to the grounding of the entire vehicle circuit in the power supply design
In terms of the drive power processing circuit, the problem of power supply shutdown and inductive load shutdown surge voltage release is not considered, so it is difficult to meet the needs of the vehicle controller

The invention relates to the technical field of an electric vehicle control system, and specifically relates to a power supply circuit of an electric vehicle controller. The power supply circuit of the electric vehicle controller, through a key switch signal end, outputs a key switch signal to a master control unit (MCU) so as to control wakening and switching of the MCU; furthermore, through arrangement of a reversal connection protection unit, reversal connection protection is provided; through arrangement of a surge voltage protection unit, surge voltage protection is provided; and furthermore, through arrangement of a MOS transistor with a freewheeling diode, reversal connection protection and turning-off control of a driving power processing circuit are realized, and inductive load turning-off surge voltages are released to a battery. Therefore, various functions and safety needs of vehicle control of an electric vehicle are taken into full consideration, thus forceful technical support is provided for improvement of the reliability and stability of the electric vehicle controller.
Description
technical field [0001] The invention relates to the technical field of electric vehicle control systems, in particular to a power supply circuit of an electric vehicle complete vehicle controller. Background technique [0002] Electric vehicles have received more and more attention due to their advantages of no pollution, low noise, simple structure, convenient maintenance, high energy conversion efficiency, and smoothing the peak-to-valley difference of the power grid. Electric vehicle vehicle controller (VehicleController) is the core component of electric vehicle vehicle control system. It plays a key role in the normal driving of electric vehicles, regenerative energy recovery, network management, fault diagnosis and processing, vehicle status and monitoring and other functions. Its performance is directly related to the overall performance of the electric vehicle, and whether the power supply design in the vehicle controller is reasonable is directly related to whether ...
