Power battery evaluation system

Abstract

The invention discloses a power battery evaluation system which comprises a battery PACK, an MCU micro-control unit and a battery detection module, the battery PACK is assembled in the battery detection module; the detection content comprises SOH internal temperature detection, SOC capacity detection, battery internal resistance detection and battery cell chemical detection. The charge state and the internal resistance of the power battery are calculated according to the detected data, data such as the maximum charge-discharge capacity is obtained, and a single chip microcomputer and a systemthereof are used for integration and calculation according to the data; finally, an overall evaluation report of the tested retired power battery is generated through an evaluation report generation module according to the performance parameters of the retired power battery. Performance evaluation of the power battery is integrally controlled by the MCU micro-control unit, the operation is simpleand convenient, the flow is rapid and convenient, each piece of detection data is compared by adopting multiple detection modes, and the generated evaluation report is more detailed, comprehensive andspecific, and the system is suitable for detection of a large batch of retired power batteries.

[0002] The power battery is the power supply that provides the power source for the tool. It mostly refers to the battery that provides power for electric vehicles, electric trains, electric bicycles, and golf carts. Lead-acid batteries, open-type tubular lead-acid batteries and lithium iron phosphate batteries are mainly used in the starting and ignition of engines in the automobile or motorcycle industry and the function of providing electric energy for on-board electronic equipment. They have high energy, high power and high The characteristics of energy density, its wide operating temperature range, long service life, generally up to 5-10 years, is a safe and reliable emerging power source in the automobile or motorcycle industry. The evaluation of decommissioned power batteries is mainly from the state of charge ( SOC), internal resistance, capacity, cycle life and consistency, etc. to conduct an overall performance evaluation of the power battery, so as to judge the recycling value of the decommissioned power battery. After the decommissioned power battery of the existing technology is recycled, its internal The evaluation of structure and performance, and the coefficients of various evaluations need to be tested for a long time through various equipment, and the data are recorded, and finally the evaluation report is manually integrated according to the data. This method consumes a long time for evaluation and detection, which is not conducive to data collection. Integrated comparison and evaluation and detection of large-scale power batteries
