Description

technical field

[0001] The invention relates to a battery pack monitoring and management device, in particular to a multi-cascade high-voltage, high-power battery pack monitoring and management device,

[0002] Battery pack monitoring and management for EVs, HEVs and other high power battery drive systems. Background technique

[0003] The energy shortage in today's society and the problem of environmental pollution have raised important issues for human beings. Various battery manufacturers have actively researched and developed various types of batteries, especially lithium-ion power batteries as the most advanced representative, thus solving this problem. However, the bottleneck in the application and promotion of lithium power batteries is mainly the failure of a single battery in the battery pack during combined applications, resulting in a decline in the overall performance of the battery pack and the battery pack being used beyond the limit.

[0004] Therefore, it is...

Embodiment Construction

[0032] In order to understand the present invention more clearly, describe the present invention in detail in conjunction with accompanying drawing and embodiment:

[0033] like Figure 1 to Figure 6 As shown, the multi-cascade high-voltage, high-power battery pack monitoring and management device includes a central processing unit ECU, a voltage acquisition module, a current acquisition module and a temperature acquisition module;

[0034] The central processing unit ECU uses MSP430F149 single-chip microcomputer, which is responsible for communicating with the system, alarming and data transmission. At the same time, it accepts commands issued by the system, detects various working conditions of the battery pack, records the detection results and sends an alarm to the system if any abnormal situation is found.

[0035] The voltage acquisition module is composed of MAX11068 and its peripheral circuits. It mainly detects the voltage and current of the single battery in the batt...
