Hioki technology can measure the characteristics of EV battery packs

The newly developed technology will directly measure the characteristics of vehicle battery packs.
Hioki is pleased to announce that it has developed technology for connecting a dedicated instrument to the rapidly changing connectors on EVs and PHEVs to measure the characteristics of vehicle battery packs. The technology makes it possible to directly measure battery pack characteristics and ascertain the battery’s condition based on the results.
Development background
Hioki supplies a wide range of testing equipment for use in lithium-ion battery (LIB) cell, module, and pack manufacturing processes. Several products, particularly impedance instruments (battery testers), have become de facto standards in the industry, and Hioki has played a leading role in quality testing since the earliest days of LIB commercialisation. More recently, the company has been developing testing technologies for manufacturing processes and new-product testing and evaluating degraded LIBs during and after use.
The transition to electric vehicles has been gathering momentum worldwide. To realise an economic growth strategy founded on decarbonisation, it is not enough to merely adopt LIBs as a power source for automobiles; it will also be essential to streamline resource recycling systems and establish an appropriate value chain. Assessing the performance of the EV battery packs will be a crucial part of building the LIB value chain. As a result, there’s a need for technology that can be used by third parties to test the condition of battery packs to evaluate EV performance, appraise used EVs, and manage automotive fleets.
However, information related to the condition of the battery packs used in EVs is generally managed by an onboard controller, making it difficult for third parties to test battery conditions. Although third parties can access LIB-related information transmitted on vehicle networks like CAN buses and use that data for diagnostic purposes, the fact that the EV itself acquires such data means that the diagnostic process cannot be accomplished entirely by third-party means.
In response to this situation, Hioki drew on impedance measurement technology developed over many years to build a solution that makes it easy to measure battery pack characteristics via the rapid-charging connectors on EVs and PHEVs.

Principal applications
Diagnosing the performance of and appraising used EVs Testing the battery pack condition during EV maintenance Testing the state of battery packs to facilitate efficient EV fleet management.
