Additional Details
The ST-C-62015-3BF is a 10 kW high-voltage on-board charger for 620 V lithium battery systems, built on the ST-C charging platform. It accepts a wide AC input — single-phase 110–240 Vac and three-phase 220/380/440/480 Vac (3P+PE) — and delivers up to 15 A across a 240–800 Vdc output window with ≤95% efficiency and power factor >0.99.
The charger is fully galvanically isolated between the AC grid and the vehicle DC system, sealed to IP67 in a cast-aluminium fan-cooled enclosure, and CAN-controlled (BMS CAN plus a master-slave bus for parallel operation to reach higher power). Comprehensive protections (input/output OVP/UVP, short-circuit, over-temperature derating, insulation-fault and reverse-polarity detection) and CE/UL/FCC compliance suit high-voltage industrial and fleet EV charging. Model code ST-C-62015-3BF (62 = 620 V class, 15 = 15 A, B = 3-phase 220–480 Vac input, F = fan cooling).
