Integrated Battery Management Evaluation Board by MPS
MBMxxS-P100-x For High-Current Designs
The MBMxxS-P100-x from MPS represents a comprehensive solution for the BMUxxS-P100-x, an evaluation board tailored for high-current designs housing a 7-16 cell battery management unit. It integrates the MP279x ICs, a robust family of battery management analogue front ends (AFEs), providing a complete AFE monitoring and protection solution. The MP279x supports up to 16 cells in series and incorporates two separate analogue-to-digital converters (ADCs) for synchronous voltage and current measurements.
DOWNLOAD DATASHEETThe high-side MOSFET (HS-FET) driver and robust hardware (HW) protection functions come with configurable thresholds. Protections include over-current protection (OCP), short-circuit protection (SCP), battery and cell over-voltage protection (OVP), battery and cell under-voltage protection (UVP), over-temperature protection (OTP) and under-temperature protection (UTP). The MP279x also integrates internal balancing FETs to equalise mismatched cells, while offering the option to control external FETs for a higher balancing current.
The evaluation board also features the MPF4279x, a standalone battery fuel gauge IC that performs state-of-charge (SoC), time-to-full, time-to-empty and unavailable energy estimation using a custom battery model obtained through exhaustive characterisation and voltage, current and temperature readings. This solution is fast, simple, and easy to configure through the graphic user interface (GUI).
The board offers a high-power solution with up to 100A of constant current and up to 150A of peak current. Each separate board offers a different combination of the MP279x and MPF4279x.
