Introducing our advanced Battery Disconnect Unit (BDU) solutions – the intelligent core of battery safety and smart control in C&I/Residential Energy Storage Systems and electric vehicles. Designed for precision, protection, and seamless integration, our BDUs ensure reliable power management, rapid fault isolation, and enhanced system stability.
Control the connection and disconnection via contactors and integrates safety components such as fuses, pre-charge resistors, and current sensors.
Integrated safety mechanisms including overcurrent protection, fault detection, and emergency disconnect systems.
Controls high-voltage circuit connection/disconnection across multiple vehicle systems with minimal power loss and maximum reliability.
Continuous monitoring of cell voltage, temperature, and current with microsecond precision and instant fault detection.
Machine learning algorithms predict battery health, optimize charging cycles, and extend overall battery life.
Active and passive cell balancing ensures optimal capacity utilization and prevents individual cell degradation.
Integrating BMU and BDU into a single intelligent module reduces system complexity and enhances performance. It minimizes wire harnesses, improves electromagnetic compatibility, and enables faster reaction to faults.
