SB-B by Maxwell: An integrated power distribution unit for a smart BMS
Solid-state relay-based Power Distribution Unit
SB-B
SB-B is an integrated Power Distribution Unit (PDU) consisting of a hall effect current sensor, pre-charge circuitry, and MOSFETs
Designed to seamlessly pair with Maxwell's LT BMS, through a specially designed wire harness kit, the LT controls the SB-B board to engage and disengage the battery by driving the solid-state relay-based power delivery channels. SB-B comes in four variants and stacks on top of LT to save space, enabling seamless integration with a battery pack.
Short Circuit Protection
Over temperature protection
Low power consumption
Up to 100A Continuous Current
Product capabilities & features.
Precharge Circuitry
The SB-B is built with precharge circuitry to protect the battery pack against inrush current from capacitive (6mF) loads
Onboard Temperature sensors
The SB-B has an onboard temperature sensor to measure PDU temperature.
Onboard Hall Effect sensor
Onboard unipolar, bidirectional 0 to 3.3V output, thermally-enhanced and fully integrated hall-effect current sensor that can measure currents up to ± 200A
Safety
The SB-B provides safety critical features such as Over-temperature cut-off, Overload Protection and Hardware-based Short Circuit Protection.

See what our customers have to say about us
We searched for the best components and technology in the world for our electric scooter, which has been developed to fulfill the highest expectations of the premium urban mobility customer in large European metropolitan areas. Maxwell Energy, with its smart BMS solution, has proven to be the perfect partner for us, and gives us the quality and scalability we need for our growth strategy.
Íñigo Raventós Basagoiti
CEO - Ray Electric Motors
The support and guidance that Maxwell Energy’s team offered to us and our customers throughout the project was invaluable. We have been able to significantly boost our business profitability and are confident about working with more customers to solve pressing battery management problems
Filip Gabryelewicz
Product Manager - Wamtechnik
Tork Motors has been engaging with Maxwell since the very beginning. We knew very early on that the range of features offered by the LT platform would be the best fit for India's first e-Motorcycle. When it comes to safety and reliability we do not compromise and have really high expectations from our suppliers. The Maxwell BMS was successful in not only meeting our expectations but exceeding them in many ways and our motorcycle is now in production with the Maxwell BMS
