Product Features

Applied to battery management systems (BMS), motor drive controllers, on‑board chargers, DC‑DC converters and high‑voltage distribution units of new‑energy vehicles. Supporting high‑voltage isolation and large‑current load, they operate stably at ‑40℃~125℃ with outstanding vibration resistance and electromagnetic suppression. Complying with ISO 26262 automotive functional safety standards, they ensure stable battery charge‑discharge, precise motor torque control and efficient energy recovery during long‑term vehicle operation.

Technical & Technological Advantages

Adopt multi‑layer high‑low voltage isolation layout to avoid signal crosstalk and electric leakage risks; integrate over‑voltage, over‑current, over‑temperature, short‑circuit and insulation monitoring multi‑protection mechanisms; optimize high‑efficiency heat‑dissipation structure to reduce thermal attenuation of power devices; apply anti‑aging and anti‑vibration craftsmanship to prevent component failure under long‑term bumpy driving; support automotive‑grade communication protocols for vehicle‑wide coordinated control.

Application Scenarios

BMS precisely monitors cell voltage and temperature to balance battery performance and extend service life; motor drive controllers realize smooth acceleration, deceleration and torque regulation; on‑board charging and DC‑DC modules complete energy conversion and stable power supply; high‑voltage distribution units ensure safe power transmission for the whole vehicle.

Production & Application Challenges

Automotive‑grade certification involves strict test standards and long verification cycles, increasing R&D costs; complex on‑board electromagnetic environment raises high requirements for EMC design; long‑term high‑voltage and high‑current operation easily causes component aging; mass‑produced automotive electronics face difficulties in balancing high reliability, performance and cost‑effectiveness.
