STMICROELECTRONICS AEK-POW-BMSLV Evaluation Board, L9963E, Battery Management System

AEK-POW-BMSLV is a battery management system evaluation board for low-voltage applications. It is built with automotive-grade components, and it is able to connect to a battery pack and to monitor both state of charge (SOC) and state of health (SOH) of each battery. It also manages battery balancing by passive discharge, thanks to the software already preloaded on the on-board SPC58EC80E5 microcontroller. The AEK-POW-BMSLV has been specifically designed to manage the battery management system for low-voltage applications: applications whose voltage range is below 60V, for example, motorcycles auxiliary power and electric bikes. The versatile CAN2.0A/B protocol facilitates integration into several systems and efficient component communication. The AEK-POW-BMSLV is equipped with two CAN ports for flexible networked connections, while four high-side channel outputs optimized power distribution. It hosts devices such as SPC58EC80E5, L9963E, L9963T, SPSB100 and VNQ7050AJ.
