New energy systems carry high current and high voltage, where one weak solder joint can become a safety hazard. Battery management, inverter and charging boards demand thick copper, disciplined thermal design and rigorous insulation spacing. XUNFEI produces heavy-copper and high-Tg boards that sustain high power density while keeping temperatures under control.

We build energy storage BMS boards, solar PV inverter boards, PCS (power conversion system) boards, EV charging pile control boards, onboard vehicle power boards, lithium battery protection boards and wind power control modules. Every board passes electrical safety and thermal-cycling validation before it leaves our plant.

A circuit board's quality and performance directly shape how well the whole system runs. Our engineers control signal routing, heat dissipation and anti-interference from the first drawing, while our mature high-multilayer and HDI board manufacturing capabilities — backed by strict quality control — ensure consistent quality and high reliability from prototype to volume production.

From board to system: our BMS and inverter boards ship inside complete energy products such as EV charging piles and storage systems. The finished charging station below is powered and validated end to end by our PCBA.
