Technical Description:

ZB300V-0001 is a high-voltage dual-voltage intelligent BMS protection board designed for industrial, service, and special-purpose robotic applications. It adopts an 88S + 8S dual battery pack architecture, supporting a 300V power system (200V–400V) and a 24V auxiliary power system (18V–30V).

The system provides multi-channel power control capability, including four independent 24V output channels (10A per channel) with individual switching control, and two 300V high-power output channels (50A per channel) with dynamic load distribution. It supports a maximum output power of 2 × 15kW on the 300V side and 4 × 240W on the 24V side, meeting the requirements of high-power robotic drive systems and low-voltage control components.

For emergency safety and remote operation, ZB300V-0001 features a fast emergency stop system with local E-stop response time ≤10ms and Bluetooth remote E-stop communication distance ≥50m. The intelligent sleep and wake-up function supports low-power standby operation under static or low battery conditions, improving system efficiency and battery endurance.

The BMS integrates high-precision battery monitoring with voltage, current, and temperature sampling accuracy of ±0.1%. It supports accurate SOC calculation with an error margin ≤3% and provides SOH estimation for predictive battery health management.

For comprehensive safety protection, the system integrates hardware-level protection functions including over-voltage, under-voltage, short-circuit, over-current, over-temperature, reverse polarity, and insulation monitoring. The over-current protection response time is ≤50μs, and power output is automatically disconnected when the temperature reaches 75℃.

The charging and discharging control system adopts a MOSFET array design, supporting a continuous current of 100A. It features soft-start control and a 100Ω passive balancing resistor to improve system stability and battery consistency.

In terms of communication and fault management, ZB300V-0001 supports CAN2.0B communication with standard and extended frames, configurable baud rates from 250kbps to 1Mbps, and dedicated message IDs. The system can store up to 100 timestamped fault records, supports fault data export, and performs automatic self-checking during startup.

The hardware architecture adopts a modular design, integrating a 16-channel ADC acquisition module capable of monitoring up to 48 battery cells, an ARM Cortex-M4 main controller operating at 120MHz, and a distributed MOSFET power switching array. Designed for harsh industrial environments, the system provides ±15kV ESD protection and an IP65-rated enclosure for enhanced reliability.

ZB300V-0001 supports CAN2.0B + RS485 communication interfaces, operates from -20℃ to +60℃, supports storage temperatures from -40℃ to +85℃, and features a compact structure with dimensions of 210.0 × 210.0 × 50.0 mm.
