TOKYO, July 25, 2022 – (JCN Newswire) – Hitachi High-Tech Corporation (“Hitachi High-Tech”) today announced the development of a service to remotely diagnose the degradation status of on-board automotive lithium-ion batteries. Achieving stable and efficient operation of the battery is becoming quite important for the deployment of electric vehicles (“EVs”). Hitachi High-Tech will start offering this service to global customers through various networks to contribute to a circular society by solving customer problems.
Hitachi High-Tech has analyzed thousands of lithium-ion batteries and its operating data, which have been remotely sampled from electric vehicles in commercial operation. This field trial contributed to developing the technology to accurately estimate the state of health (SOH) degradation of lithium-ion battery packs and cells. It has also been demonstrated to keep track of the time series SOH of on-board batteries and to monitor changes from past to present. This will allow customers to centrally manage a large number of electric vehicles in commercial operation efficiently.
This field trial was conducted in collaboration with ITOCHU Corporation (“ITOCHU”). ITOCHU has a fleet management capability(1) and will start proposing this service to its global network that includes car manufacturers, fleet leasing and financial companies.
Background for service development
Achieving stable and efficient management of the car fleet is becoming very important for the spread of electric cars, which is growing rapidly towards the realization of a CO2-neutral society. To date, it has been necessary to remove the batteries from the vehicle to diagnose the degradation of on-board batteries, but the introduction of this service makes it possible to monitor the degradation remotely and provide an operating environment to make the most of the battery’s life. The management of the built-in usage history will also lead to the development of opportunities to utilize used electric cars for energy storage system or efficient recycling for material recovery. In particular, this service is expected to promote the transition to electric vehicles in the commercial sector, where the utilization rate of the vehicle is higher due to long driving distance with extended operating time, which will have a large impact on battery degradation.
In 2020, Hitachi developed the High-Tech Rapid diagnostic method(2) for battery degradation that instantly assesses the performance degradation and remaining life of lithium-ion batteries. In addition, the technology released this time has been developed in collaboration with the Research and Development Group of Hitachi, Ltd.
Our technology has also traditionally contributed to battery safety by using x-ray foreign material analysis system, which can perform everything from foreign material detection to elemental identification in the manufacturing process of lithium-ion batteries.
Hitachi High-Tech aims to contribute to the realization of a circular society by supporting the entire life of the battery. Hitachi High-Tech will solve social problems with our customers through observation, measurement and analysis and contribute to the realization of a sustainable society.
