Integrated test solution for power battery

With the continuous improvement of the requirements for the cruising range of new energy vehicles, the trend of the development of power batteries to high energy density has become more and more obvious. Whether the power battery can guarantee high-quality product performance before delivery to the customer is inseparable from the role played by the excellent battery detection system.

“It is very important to maintain stable consistency from battery production to PACK grouping.” Li Bing, deputy general manager of Shenzhen Ruineng Industrial Co., Ltd. (hereinafter referred to as “Reneng”) Co., Ltd., said in an interview with OFweek Lithium Grid. In the production and manufacturing of battery cells for power batteries, the testing process is indispensable, and the precise power battery detection system plays an irreplaceable role in improving the quality of battery products.

Recently, at the 2018 CIBF exhibition held at the Shenzhen Convention and Exhibition Center, Ruineng brought the overall power battery test system solution from the battery core to the PACK link. The power battery pack EOL test system is the highlight of this show.

Li Bing introduced that the Ruineng Power Battery EOL test system integrates high-power battery pack charging and discharging unit, BMS function detecting unit, battery pack insulation withstand voltage test unit and auxiliary function test unit into a complete set of electric vehicle battery pack detection system. It can meet the intelligence and automation of the whole test process, so as to reduce the operator and improve the test efficiency.

It is understood that this system is rich in functions, can achieve comprehensive rapid test of the performance parameters of electric vehicle battery pack charge and discharge performance, DC internal resistance, SOC adjustment, BMS acquisition data comparison, insulation withstand voltage, etc. Performance parameters meet national standards and manufacturer requirements.

"Renergy Power Battery Pack EOL test system can verify the compatibility of battery pack and BMS through the simulation of large-capacity charge and discharge process, and find potential quality defects." Li Bing told OFweek lithium grid, currently Ruineng has formed From the single cell to the overall test system of the PACK module.

Based on an independent R&D structure, Ruineng's battery test equipment is generally ahead of the industry average. "We continue to improve the performance of test equipment in combination with the needs of our customers. We are constantly iteratively updated every year to serve our customers with higher performance and lower cost test solutions." Li Bing introduced.

Up to now, Ruineng's customers have covered the first-line power battery companies at home and abroad, and began to access MES and cooperate with big data analysis to empower the power battery enterprise "smart manufacturing" on the test side.
