Safe to the EV battery to home use, "JET Reuse Battery Certification" started

The Institute of Electrical Safety and Safety and Environment (JET), which conduct tests and certification businesses for electrical products, etc., reuses in -vehicle storage batteries, etc., and to apply to home and business and industrial storage systems (BESS)."JET Reuse Battery Certification", which aims to ensure safety, has begun on February 1, 2022.■ In January 2021, the government has launched a ratio of electric vehicles (EVs) in new car sales of new cars by 2035.Earlier in the new year, Toyota held a "Battery EV Strategy Briefing Session" and showed off electric vehicles in all 16 models.Automobile manufacturers have announced a series of aggressive shifts to EVs, with President Toyoda stating that "we aim for 3.5 million units per year with the global sales volume of battery EVs in 2030."Is expected.Along with this, the reuse and recycling of in -vehicle lithium -ion batteries, which are expected to increase the needs of the EV's spread and expansion, are likely to increase.According to JET director and technical director, Junkichi Sumitani, "Lithium -ion batteries for in -vehicles are used for 5 to 10 years, so they need to be replaced. The products reused from there are high output and high output.Although it is not suitable for re -use for in -vehicle use that requires a capacity, it can still be used as a fixed -powered power system, such as hospitals, local governments, companies and homes. "However.In response to this task, the "JET Reuse Battery Certification" announced this time enables the fact that the safety of the reused in -vehicle battery, etc. is inspected, confirmed, and authenticated, so that it can be linked to the electric power system.。The price can be obtained at a lower price than the new storage battery, so he appeals to the reuse of lithium batteries, including in -vehicle use.■ In the "JET Reuse Battery Authentication", which has an important meaning now this timing, performs the safety confirmation necessary to reuse the storage battery to other products such as the constant storage system from a mobile application such as EV.The Jet Reuse battery authentication mark is given to the battery module (reused battery).In order to obtain "JET Reuse Battery Certification", (1) deterioration analysis is performed by the non -destructive diagnosis method specified by JET, and the reuse battery is selected within the deterioration standard maintained safety.What is done (2) Configures the reuse battery to the safety standard (JIS C 8715-2) of the storage battery required for the constant storage system.In order to confirm that there is no, the reuse battery, which is the most closest to the deterioration criteria, conforms to the JIS -resistant test.It is necessary to meet the above three requirements.The reuse battery that meets the requirements of authentication can be one of the two "JET Reuse Battery Authentication Mark" prepared by the parts authentication status of unused storage batteries.A business operator that manufactures a fixed -storage system using a reuse battery will be able to efficiently confirm the safety battery safety by confirming the "JET Reuse Battery Certification Mark".Mr. Sumitani said, "For the authentication of the existing co-storage system, the authentication and product safety authentication (S-JET authentication), it is essential that the battery is a parts certification that applies JIS C 8715-2.There is. If JET reuse battery authentication has been obtained, it can be used in an existing authentication system like unused batteries. "Of course, there are many issues to be solved in the future."How much identification can be done in a low price and efficient way. It is essential to cooperate with automobile manufacturers and battery manufacturers who focus on reuse used batteries, research and commercialization of recycling," said Sumitani.do."First of all, it starts with corporate use in the backdrop of SDGs and other companies, and demand will be increasing, and at the next stage, it may be popular for home -use power storage systems," he said.Regarding the safety of the storage battery for the fixed -storage system, which was different from the vehicle use, "it is important to maintain the scheme to confirm before the spread of electric vehicles is in full swing. EVs will be popular in the future.Mr. Sumitani complains about the importance of the timing of the introduction, saying, when the reuses of lithium batteries for in -vehicle are in full swing."We still have a lot of consultations to us. It is important to show the seriousness for that in order for the industry to build a scheme."With the start of JET reuse battery authentication, the increase in used value of the EVs that will be popular and the battery installed there will be boosted, and it is expected that the flow towards the future will be accelerated.
