Embodiment 1

[0038] figure 2 Shows the preferred embodiment of the application ( figure 2 It shows a schematic structural diagram of a controller power supply system with high reliability and zero power consumption provided by the first embodiment of the present application). For the convenience of description, only the parts related to this embodiment are shown, and the details are as follows:

[0039] It includes the main control module BCU of the battery management system, the power supply relay K1, the first anti-series diode D4 and the second anti-series diode (D1, D2, D3), and the power supply relay K1 is connected to the normal power supply and the battery management system main Between the power signal input ends of the control module, the coil end of the power supply relay K1 is connected to the self-locking power control signal output end of the main control module of the battery management system through the first anti-series diode, and the coil end of the power supply relay K...

Embodiment 2

[0054] Such as image 3 Shown is a preferred embodiment of a controller power supply method with high reliability and zero power consumption, and its process is as follows:

[0055] Step 1, power on the BMS system.

[0056] Step 101: Turn the key switch to start the vehicle (START gear) or in the ON gear or plug in the national standard charging fast charging gun (that is, A+ has power input), that is, the front end of the hardware (D1 or D2 or D3) has power.

[0057] Step 102: After passing through the reverse series diodes (D1-D4), the coil of relay K1 is energized and closed.

[0058] Step 103: The single-chip microcomputer of the BCU module is powered on and starts to run.

[0059] Step 2, the power supply of the BMS system is self-locking.

[0060] Step 201: the single chip microcomputer executes the IO port initialization program.

[0061] Step 202: The single-chip microcomputer program outputs a high level to the power self-locking control port (ie, BMS_Power_C).

Abstract

The invention relates to the technical field of automobile power supply, in particular to a high-reliability controller power supply system with subzero power consumption, a method and a storage medium. Comprising a battery management system master control module, a power supply relay K1, a first anti-reverse-serial-connection diode and a second anti-reverse-serial-connection diode, and the power supply relay K1 is connected between a constant power supply and a power signal input end of the battery management system master control module. The coil end of the power supply relay K1 is connected with the self-locking power supply control signal output end of the battery management system master control module through a first anti-reverse-serial diode, and the coil end of the power supply relay K1 is connected with the activation signal output end through a second anti-reverse-serial diode. A power supply loop activated by an external signal and self-locked by the controller is established, and power supply locking, data storage before power-off, power-off control and the like are realized by software of the controller. The stability of power supply control and data storage of each controller is ensured, and meanwhile, zero power consumption in a power-off state is realized.

Description

technical field [0001] The invention relates to the technical field of automobile power supply, in particular to a controller power supply system, method and storage medium with high reliability and sub-zero power consumption. Background technique [0002] With the continuous improvement of the electrification and intelligence of the vehicle system, the number of controllers is increasing, the power consumption of the vehicle is also increasing in the dormant state, and the complexity of the coordinated management of the vehicle power supply is also gradually increasing, especially in the controller The complexity of power-on activation and power-off data storage control is greatly increased. [0003] The existing controller power supply mainly adopts the following two methods: [0004] 1. All components are powered by constant power. The power supply circuit of the controller uses a power supply chip with sleep / wake-up function. The power-on wake-up of the controller is re...
