| Overview of the Service |
Field Trial and Service outline
Hitachi High-Tech has analyzed thousands of lithium-ion batteries and its operational data which is remotely taken from EVs in commercial operation. This field trial contributed to develop the technology to estimate the degradation of State of Health (SOH) of lithium-ion battery packs and cells accurately. It has also been demonstrated to keep track of the time-series SOH of on-board batteries and to monitor changes from the past to the present. This will allow customers to centrally manage a large number of EVs in commercial operation efficiently.
This field trial was carried out in collaboration with ITOCHU Corporation (“ITOCHU”). ITOCHU has a capability of automotive fleet management(1) and will start proposing this service to its global network that include automotive manufacturers, fleet leasing and financial companies.
Background of Service development
Achievement of stable and efficient automotive fleet management is becoming quite important for the deployment of EVs that grows rapidly towards the realization of a carbon-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 enables to monitor the degradation remotely and provide an operational environment to make the most of battery life. The management of the on-board usage history will also lead to development of…
