How to Identify a Professional BMS Factory in China Before Importing
31,Oct 2025
KURUI Electronics, a subsidiary of Huarigor, was founded in 2018 with a focus on smart and high-current BMS systems for lithium-ion batteries used in EVs, energy storage, and light electric vehicles.
Located in Dongguan, China, KURUI leverages the region’s mature electronic supply chain, ensuring high-precision manufacturing and consistent product quality. With full-scale production lines, testing labs, and an integrated R&D center, KURUI has quickly established itself as a trusted EV BMS supplier in both domestic and international markets.
The company’s mission is clear — to empower electric vehicles with smarter, safer, and more durable battery management systems.
A smart BMS (Battery Management System) is more than just a monitoring board. It integrates hardware sensors, data communication, and intelligent algorithms to ensure optimal performance and protection of lithium battery packs.
Key functions include:
Real-time voltage and current monitoring
State of Charge (SOC) and State of Health (SOH) estimation
Cell balancing and thermal management
Protection against overcharge, over-discharge, short circuits, and overheating
Communication via CAN, RS485, or Bluetooth modules
In contrast to a standard BMS, the high-current smart BMS is optimized for extreme load and rapid charge/discharge cycles, often used in EVs, e-bikes, and energy storage systems.
Operating under high-current conditions introduces a unique set of challenges:
| Challenge | Description |
|---|---|
| Power Loss Control | Low resistance components are needed to reduce energy loss. |
| Thermal Management | Increased current leads to heat buildup that must be efficiently dissipated. |
| Measurement Accuracy | Precision in detecting voltage and current across cells is critical. |
| Response Time | The system must react instantly to abnormal conditions. |
| Cell Balancing | Maintaining uniform performance across all cells under stress. |
KURUI’s engineering team addresses these with advanced circuit design, high-grade materials, and intelligent control algorithms.
