The battery management system includes a slave control management component, which is installed in the battery box and connected to each single battery through a collection harness. It monitors and collects the status parameters of each single battery in the battery box in real time (including but not limited to single battery voltage, battery pole temperature, battery loop current, battery pack terminal voltage, battery system insulation resistance, etc.), and manages the single battery according to the control strategy.

[0027] Please refer to Figure 1-3 , shows a slave control management component provided by an embodiment of the utility model, which includes a slave control module and a slave control housing.

The circuit board is welded with acquisition circuits and execution circuits related to battery management, and is mounted with related electronic components. Multiple harness connectors are connected to the circuit board. One end of the acquisition harness is connected to the harness connector, and the other end is connected to the single cell battery. The slave control housing includes a cover 10 and a base plate 20. The cover 10 is detachably connected to the base plate 20. The slave control module is installed on the base plate 20, and the cover 10 covers the top of the slave control module. As shown Figure 1 As shown, the housing 10 has a cavity inside, and the slave control module can be accommodated in the cavity, so as to be protected by the housing 10. Specifically, the housing 10 includes a first side panel 11 and a second side panel 12, which are arranged opposite to each other and are respectively located on both sides of the length direction of the housing 10, and the angle between the first side panel 11 and the bottom panel 20 is less than 90 degrees. A plurality of connectors 113 are provided on the first side panel 11, and the harness connector 31 on the slave control module can be engaged with the connectors 113 to fix the harness connector 31, so as to facilitate the plugging and unplugging of the collection harness. The plurality of connectors 113 vertically penetrate the first side panel 11, and when the slave control housing 10 is installed on the battery box, the bottom panel 20 can be placed horizontally, and the first side panel 11 is inclined, so that the collection harness can be obliquely connected to the slave control module, which reduces the demand for the turning radius of the harness, increases the operating space, is convenient for plugging and unplugging, and is easy for installation and maintenance. Preferably, the angle between the first side plate 11 and the bottom plate 20 can be between 70 and 75 degrees, so that the line outlet can have an angle of 15 to 20 degrees, which increases the operating space.
