Import Battery Management System Bms — Buy in wholesale FOB from Supplier in China

This Battery Management System from Jiangsu Acrel Electric Manufacturing Co., LTD is designed for lithium battery packs powering electric vehicles, electric boats, and stationary electric equipment. It performs real-time monitoring of individual cell voltage, total pack voltage, cell temperature, and charge and discharge current. The system also manages cell balancing, controls charge and discharge relays, regulates heating and cooling, and issues fault alarms when protective thresholds are breached. Communication to host systems or monitoring computers is via an RS485 interface with dedicated configuration software.

The BMS implements a multi-layer protection strategy. On power-up, both charge and discharge relays close if battery status is normal. Over-charge and over-discharge conditions trigger relay disconnection at pack and cell level, with automatic reconnection only when release voltage thresholds are reached. Temperature protection operates similarly for charge and discharge paths. Over-current events in either direction latch the respective relay off until the next power cycle, a conservative approach that prevents repeated fault cycling. The RS485 link allows parameter configuration and live telemetry logging, which is essential for fleet operators and system integrators needing predictive maintenance data.

Jiangsu Acrel Electric Manufacturing Co., LTD produces this BMS in Jiangyin, Jiangsu Province, within China's Yangtze River Delta manufacturing belt. The unit suits OEMs of electric forklifts, marine propulsion systems, energy storage cabinets, and electric two-wheelers. Buyers should confirm the maximum series cell count, continuous and peak current ratings, and whether the hardware supports the specific lithium chemistry in use (LFP, NMC, LTO). Certifications, IP rating, and EMC compliance levels must be verified directly with the supplier, as these are critical for vehicle and marine regulatory approval.

Jiangsu Acrel Electric Manufacturing Co., LTD operates from Jiangyin, Jiangsu Province, China (postal code 214400), situated in the Yangtze River Delta, one of China's densest concentrations of electrical equipment and electronics manufacturing. The supplier holds a harbour trust tier. The response rate shows 0.00 percent with zero average response hours, so no communication pattern data is available. The company's product focus is on battery management systems for lithium-powered applications, spanning mobility and stationary energy storage sectors.

The supplier profile does not disclose year of establishment, registered capital, factory size, employee count, annual revenue, or named customers. No ISO, IATF, UL, or CE certification numbers appear in the available data. Buyers should independently verify manufacturing scale, R&D capability, software version control processes, and field deployment history. Given that BMS products require ongoing firmware support and calibration data, assess whether Jiangsu Acrel Electric Manufacturing Co., LTD provides long-term technical support and software updates before committing to volume supply agreements.
