Solutions for EV & Battery Systems
Electric vehicle development and battery storage engineering demand instruments that can handle high currents, wide voltage ranges, and complex mixed-signal environments. From battery cell characterization to BMS debugging to charging circuit validation, UNI-T provides the precision tools that EV engineers rely on — at price points that let you equip every bench.
Oscilloscopes — Mixed-Signal Debugging for BMS & Power Electronics
Battery management system debugging requires simultaneous analog and digital capture. The MSO5034HD (350MHz, 12-bit) provides the signal fidelity needed to analyze switching transients in DC-DC converters and inverter drives, while its 16-channel logic analyzer captures CAN, SPI, and I2C communication between BMS modules. For higher bandwidth requirements in power electronics R&D, the MSO5104HD (1GHz) handles fast switching edges in GaN and SiC designs.
For production validation and field service, the MSO3034HD offers an excellent balance of performance and value with CAN/LIN bus decoding built in.
DC Power Supplies & Electronic Loads — Battery Simulation & Testing
Simulating battery charge and discharge cycles requires programmable power supplies and electronic loads working in tandem. The UDP6952B (600W, 60V/25A) provides the high-current output needed for battery charging simulation, while the UTL1040S (400W DC load) handles discharge testing with programmable constant-current, constant-voltage, constant-power, and constant-resistance modes.
For lower-power cell-level testing, the UDP3305S (4-channel linear supply) provides the low-noise, precise output needed for individual cell characterization.
Power Meters — Efficiency & Compliance Testing
Measuring charger efficiency and validating power conversion stages requires dedicated power analysis. The UTE310 provides 300kHz bandwidth with harmonic analysis up to the 50th order — essential for evaluating switching power supplies and onboard chargers. For three-phase systems like EV motor drives, the UTE323 handles simultaneous 3-channel measurement with high-precision 0.1% accuracy.
Field & Service Tools
EV service technicians need rugged, reliable handheld instruments. The UT197 industrial TRMS multimeter with Bluetooth provides CAT III 1000V / CAT IV 600V safety ratings and wireless data logging. For high-current measurement on battery packs, the UT222 clamp meter handles up to 2500A AC/DC. The UT512E insulation resistance tester (2500V) validates battery pack isolation integrity.
Thermal imaging reveals hotspots in battery packs, charging connectors, and power electronics before they become failures. The UTi720A (256×192) is built for industrial inspection, and the UTi260B offers heavy-duty durability for shop environments.
