Diagnosing the degree of deterioration of batteries installed in electric vehicles in a short time, and demonstrating at car dealers

Toyo System's battery evaluation device. Aiming to commercialize degradation diagnosis based on cultivated technology

Toyo System Co., Ltd. (Iwaki City, Fukushima Prefecture, President Hideki Shoji) will demonstrate technology for quickly measuring and diagnosing the degree of deterioration of lithium-ion secondary batteries (LIB) installed in electric vehicles in January 2022. to start. It will be held at two car dealers in the Tokyo metropolitan area. Through demonstration, we aim to commercialize it from October of the same year. This will lead to the revitalization of the used electric vehicle market and the reuse of LIBs for renewable energy. [Illustration] There is no loss in knowing, technology to demonstrate the mechanism of lithium-ion batteries uses battery diagnostic equipment installed in electric vehicles and the like to measure current, voltage, and battery temperature in about 30 seconds. Get data. The internal resistance increase rate is calculated based on the simulation of the initial characteristic model of the battery, and the remaining battery capacity is instantaneously measured. Evaluation of the degree of deterioration is performed on a cloud basis. The introduction cost is 200,000 to 300,000 yen. Toyo System has about 40 patents for this battery evaluation system, and another 60 are under review. When commercialization is scheduled for October, the fee for one diagnosis will be around 5,000 yen (including consumption tax), and the fee will be reduced as the system becomes more widespread. If the number of dealers with evaluation systems increases, a data analysis center will be set up. Being able to accurately and simply measure the degree of deterioration of LIBs will facilitate the expansion of the second-hand electric vehicle market and the reuse of stationary backup power sources for renewable energy. In addition, we are considering reducing carbon dioxide (CO2) emissions by storing and using renewable electricity in reusable batteries on a factory-by-factory basis.
