Power Management: FSB-B
FSB-B
Introduction
The FSB-B is an integrated Power Distribution Unit that works with the FS-LT Smart Battery Management System. It’s solid-state relay based power delivery channel protects the battery against a load-side short circuit. The maximum allowed voltage is 63V and it comes in two variants, based on the maximum current it can support, 40Amps (FSB-B-40) and 70 Amps (FSB-B-70) respectively.
The FSB-B consists of a Hall Effect Current Sensor, Pre-Charge Circuitry and Mosfets. It can be easily connected to the FS-LT with a specially designed wire harness kit.
Functions
> Connect/Disconnect the battery from the external
application based on BMS commands.
> Enable the BMS to control the charge discharge and
precharge paths.
> Report short circuit state to the BMS ensuring battery safety.
> Report the raw current value to the BMS.
> Report the temperature of the PDU to the BMS
Features
Low energy profile
> Supports one unipolar, bidirectional 0 to 3.3V output,
thermally-enhanced and fully integrated hall-effect current
sensor with a 100uOhm current conductor. It can measure
currents up to ± 200A.
> On board pre-charge channel with capability to precharge
3.5mF load capacitance.
> Solid state relay based power delivery channel with anti-
series combination of Power Mosfets.
> Isolated input for driving the MOSFETs and sensors.
> 1 onboard temperature sensor
> 1 digital channel for PDU error reporting for any short circuit
error or terminal removal conditions.
Applications
> Swappable Battery Systems
> Electric 2 & 3 Wheelers
> UPS/Backup Battery Systems
