HEV/EV battery-management system (BMS)

Accurate monitoring

Battery monitoring integrated circuits (ICs) measure cell voltages and temperature and perform cell balancing to monitor and protect the cells. Accurate monitoring enables more efficient battery use, resulting in longer run time and a reduction in battery size and cost.

The pack monitor performs high voltage, current and temperature measurements to diagnose and manage the safety of the battery packs. Our battery cell monitoring ICs and pack monitors are designed to work together, to enable synchronized measurements of cell voltage, pack voltage and current.

Enabling higher-density battery packs

Revolutionize electric vehicle (EV) battery management with the industry’s leading network availability for wireless BMS, featuring an independently-assessed functional safety concept that empowers automakers to reduce the complexity of their designs, improve reliability and reduce vehicle weight to extend drive range.

Benefits:

• Improve system cost and reduce production complexity by eliminating wiring harness.
• Enable new architectures to better use available space and to design higher density battery packs.
• Speed up the assembly pace and get to market faster with higher degree of automation by removing heavy, expensive, maintenance-prone wires and using less connectors.

Improve safety and efficiency in battery disconnect systems

Software-programmable integrated contactor driver and  integrated squib driver for pyro fuses offer built-in diagnostics to develop smarter, more advanced battery management systems (BMS). 

Benefits:

• Reduce design complexity with integrated solution with built-in diagnostics and protection, developed for functional safety applications.
• Support higher voltages in HEV/EV systems with minimal power loss to enable higher HEV/EV mileage.
  
• Enable rapid shutdown of high-voltage electric currents with pyro fuse (in less than 50 usec).

Delivering industry-leading reliability

Our portfolio of solid-state relays deliver industry-leading reliability to help make electric vehicles safer.

Benefits:

• Increase reliability with 10 times higher operating lifetime than electromechanical relays.
• Reduce system size and cost by up to 50% with integrated power and signal isolation.
• Improve safety of 800-V EV battery-management systems:  solid-state relays survive more avalanche current than traditional photorelays, eliminating the need for a reed relay disconnect.
