As electric vehicles surge worldwide, the demand for reliable power conversion systems has skyrocketed, placing on-board chargers (OBCs) at the forefront of innovation. Japanese precision engineering major, Kikusui Electronics has introduced advanced testing platforms designed specifically for validating OBCs, traction batteries, and bidirectional power electronics amid rising needs for vehicle-to-grid (V2G) and vehicle-to-home (V2H) capabilities.

These EV Power Testing Solutions tackle the complexities of modern EV power systems, where OBCs must handle diverse AC inputs from residential outlets to public fast-charging stations while delivering stable DC output to high-voltage batteries.
Kikusui’s toolkit addresses key challenges like grid disturbances, harmonic distortions, and transient loads that can compromise efficiency, battery longevity, and safety.
Core Testing Platforms
Kikusui Electronics PCR-WEA/WEA2 series programmable AC/DC power supplies stand out for AC-side evaluation. Capable of simulating global grid standards such as single-phase 120V (US), 200V three-wire (Japan), and three-phase 208V, this lineup spans 1kVA to 36kVA models, expandable to 144kVA in parallel setups.
Engineers praise its ability to replicate voltage sags, frequency shifts, interruptions, and up to 40th-order harmonics for IEC 61000 compliance testing, ensuring OBCs thrive under real-world variability.
On the DC side, the PXB series bidirectional DC supplies (up to 1,500V) and PLZ-5WH2 series high-speed electronic loads (up to 1,000V) enable precise battery-side validation.
These tools support regenerative operation to cut energy costs during long endurance tests, mimicking charging/discharging cycles while measuring ripple, regulation, and dynamic response.
Integrated System Benefits
Combining these instruments creates a seamless end-to-end testbed for OBCs integrated with DC/DC converters and junction boxes trends driving compact, multifunctional EV designs.
Features like 4x peak current handling, 5kHz frequency range, and advanced sequencing streamline global certification, shorten development timelines, and boost power quality analysis.
Widely trusted in Japan’s automotive sector, Kikusui Electronics systems empower engineers to optimize performance for next-gen EVs, from modular chargers to energy-storage applications. This positions the company as a vital ally in scaling reliable, efficient electric mobility.
