从China供应商批发进口72v Liquid Cooled Obc Lithium Battery Charger — FOB条款

This 72V liquid cooled on-board charger (OBC) is built for lithium battery packs in electric vehicles, e-bikes, and scooters, using internationally recognised semiconductor devices from IR, TI, ST, and ON. The unit achieves a charging conversion efficiency of up to 94%, with full charge voltage options spanning 54.6V, 57.6V, 71.4V, 72V, and 86.4V to suit diverse pack configurations. Integrated over-temperature and low-power protection circuits are standard, and the liquid cooling architecture permits sustained high-current operation without the thermal throttling common in air-cooled designs.

The hardware platform centres on a PCBA with an aluminum heat sink for thermal management, with liquid coolant circulated through dedicated channels to maintain junction temperatures within semiconductor limits. The component bill draws from established power-semiconductor suppliers (Infineon IR, Texas Instruments, STMicroelectronics, ON Semiconductor), indicating a design oriented toward reliability rather than lowest-cost sourcing. Typical OBC designs in this class operate across an input range of 90-264V AC for global compatibility, though buyers should confirm the exact input specification with the supplier.

Target buyers include OEMs of electric two- and three-wheelers, low-speed EVs, and battery pack integrators requiring CAN or enable-signal interfaces for BMS communication. The 72V nominal output aligns with common e-motorcycle and e-scooter architectures, while the multiple full-charge voltage set points accommodate both lithium iron phosphate (LFP) and NMC/NCA chemistries. Importers should verify CCC certification status for domestic Chinese use, or CE/UL markings for export markets, plus the specific Incoterms and MOQ for bulk orders.

Shenzhen Depowersupply Electric Co., Ltd. is located at 7th Floor, Block A, Xin Weirun Hi-Tech Industry Area, No.36 Pinggang Road, Jiangshi Gongming Town, Guangming New District, Shenzhen, Guangdong Province, 518100, China. The company holds a Harbor trust tier on the platform, though its response rate is recorded at 0.00% with an average response time of 0 hours, suggesting limited or no active engagement through platform messaging at the time of listing. The supplier's product line focuses on EV charging hardware, specifically on-board chargers for lithium battery applications.

The listing provides a physical address in one of Shenzhen's industrial zones but doesits not state factory ownership, production capacity, employee count, or year of establishment. No certifications (CCC, CE, UL, ISO) are listed, and no client references or export history are mentioned. Buyers should treat this as an unverified trading or manufacturing entity and conduct independent due diligence, including a factory audit if order values justify it, before committing to volume purchases.
