Optimizing vehicle performance, safety, and cost with measurement technologies that support the EV lifecycle
The widespread adoption of electric vehicles depends on three key factors: highly efficient drive systems, safe and reliable electrical design, and cost optimization in both manufacturing and maintenance.
HIOKI provides advanced electrical measurement technologies that support every stage of the EV lifecycle — from development and mass production to after-sales service.
These measurement solutions directly contribute to improving energy efficiency, reducing the risk of failure, and enhancing production efficiency, ultimately enabling EVs to become longer-lasting, safer, and more reliable products.
Electric drive system (inverter-motor system)
To balance energy efficiency with drive performance, vehicle drive systems are evolving in a more integrated and sophisticated manner.
HIOKI’s power analyzers precisely capture the highly dynamic energy flow that occurs during driving, supporting control system design and improving overall efficiency.
They are also used for evaluations under real-world driving conditions and in inspection processes during mass production — helping enhance both the quality and reliability of electric vehicles.

Thermal and energy management
As drive systems and batteries become more advanced, thermal management has become a critical issue directly linked to vehicle safety and comfort.
HIOKI’s data loggers can simultaneously and accurately record multiple sensor signals — including temperature, voltage, current, and vibration.
They support optimization of cooling design by enabling detailed understanding of the thermal characteristics of batteries and power units, thereby contributing to the long-term reliability of next-generation vehicles.

EV Maintenance Tools
EV maintenance requires both high-voltage and high-current safety assurance, as well as precise electrical testing.
HIOKI offers a wide range of test tools — including insulation resistance testers, ground continuity testers, and non-contact CAN sensors — that enable efficient and accurate diagnostics.
These solutions support safe and reliable inspection work in the field, ensuring the long-term performance and safety of electric vehicles.
