A testing device for an ex-service lithium ion battery pack of an electric automobile comprises a base, one side of the base is provided with a first belt type conveying mechanism in a matched mode, the two sides of the top face of the base are provided with placing plates in a matched mode, one placing plate is provided with a first clamping mechanism in a matched mode, and the other placing plate is provided with a second clamping mechanism in a matched mode. A battery capacity testing device is fixedly installed on the top face of the base, a frame is installed on the other side of the base in a matched mode, an upper partition plate and a lower partition plate are installed in the frame and divide the interior of the frame into three cavities, and a second belt type conveying mechanism is arranged at the bottom end of each cavity in a matched mode. According to the single battery capacity testing device, different modes can be selected for clamping operation according to the placement state of the single battery on the first belt type conveying mechanism, single battery capacity testing and capacity testing of a battery pack formed by connecting a plurality of single batteries in parallel can be carried out according to requirements, single battery testing in a traditional mode is met, and the testing efficiency is improved. And the battery pack has the advantages of short time and low cost.
Description
technical field [0001] The invention belongs to the field of testing equipment for decommissioned lithium-ion batteries, in particular to a testing device for decommissioned lithium-ion battery packs of electric vehicles and a method for using the same. Background technique [0002] With the intensification of energy crisis and environmental pollution, transportation energy transformation is imperative. Electric vehicles using green and environmentally friendly lithium-ion batteries as power sources can effectively reduce road emissions, and are highly valued by domestic and foreign automobile research institutions and manufacturers. However, the cost of the power battery pack is high, and when its capacity decays to 70-80% of the rated capacity, the battery pack will be decommissioned. Although the decommissioned battery pack cannot meet the needs of electric vehicles, its capacity can fully meet the use of energy storage equipment, and still has great reuse value. At this...
