Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0048] Such as figure 1 As shown, a BMS control method includes a power-on control method and a power-off control method.

[0049] The power-on control method specifically includes:

[0050] Step S11, turn on the low-voltage power to the BMS, and after the BMS passes the self-test, go to step S12.

[0051] Step S12, check whether the output current of the battery is less than N1 ampere, if not, determine the failure, and issue a power-on abnormal alarm; if yes, go to step S13. The value of N1 is 1.

[0052] Step S13, judging the operating mode of the battery, if it is the discharge mode, go to step S14; if it is the charging mode, go to step S16.

[0053] Step S14, receiving the instruction...

Abstract

The invention discloses a BMS control method which comprises a top electric control method, a bottom electric control method and a PTC heating control method. Compared with the prior control, the BMS control method is more rigorous and the viscosity phenomenon can't be generated; meanwhile, top electric and bottom electric control can enable the generated code to better conform to control logic through modular setting, which can't generate an error.

Description

technical field [0001] The invention relates to a BMS control method and belongs to the technical field of battery charging and discharging. Background technique [0002] The battery management system (BATTERY MANAGEMENT SYSTEM) The battery management system (BMS) is the link between the battery and the user. status. The logic of the existing BMS control relay is not rigorous enough, which will cause the relay to stick during power on and off. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a BMS control method. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A BMS control method, including a power-on control method and a power-off control method, [0006] The power-on control method specifically includes: [0007] Step S11, connect the low-voltage power to the BMS, and after the BMS passes the self-test, go to step S12; [0008] Step S1...
