Embodiment Construction

[0038] Such as figure 1 As shown, a battery pack with an integrated BMS control board includes a battery pack PACK and an integrated BMS control board. The integrated BMS control board includes battery control unit BCU, central control unit CCU, data control unit DCU and power control unit PCU.

[0039] The battery pack PACK is composed of single cells connected in series and parallel.

[0040] The battery control unit BCU realizes the voltage collection and current collection of the battery pack PACK, the battery temperature collection, controls the output control of the battery pack PACK, and communicates with the central control unit CCU.

[0041] Its specific functions are:

[0042] a. Collect the battery voltage and current of the battery pack PACK, the temperature of the battery pack PACK, and control the temperature of the power tube;

[0043] b. Protection against short-circuit, over-temperature, over-current, over-voltage, under-voltage and various abnormalities ...

Abstract

The invention discloses a battery pack with an integrated BMS control board, which is characterized in that it includes a battery pack and an integrated BMS control board, and the integrated BMS control board includes a battery control unit, a central control unit, and a data control unit and power control unit. And the layout of the integrated BMS control board and the working method of the battery pack with the integrated BMS control board. In the present invention, the functional modules on the battery control board are divided into four independent modules: battery control unit, central control unit, data control unit and power control unit, so that each unit can work independently during standby, thereby reducing energy consumption. In addition, through the location arrangement of each unit on the battery control board, the signal interference between the wireless communication module, the positioning module and the short-distance communication module is small, which is beneficial to the integration and miniaturization of the control board. Through the setting of different working modes, the purpose of reducing power consumption is achieved.

Description

technical field [0001] The invention belongs to the technical field of energy storage equipment, and in particular relates to a battery pack with an integrated BMS control board, a control board arrangement and a working method. Background technique [0002] In the lithium battery used for energy storage and backup power, the lithium battery management system is generally an independent board system, which only performs short-circuit control and information collection on the lithium battery, and transmits or receives the monitored information for remote control. Use traditional RS485 or RS232 to connect with the host computer. [0003] Under the requirement of increasingly miniaturized energy storage and backup power, and there is a demand for the battery to be monitored throughout its life cycle after leaving the factory, a communication function for miniaturized batteries is needed, which can collect battery information at any time and In abnormal circumstances, the contr...
