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.
