Overview

Description

This 6- to 10-cell motor solution is a 4-board solution that powers motor applications using 24V to 36V batteries. The battery pack provides power to the motor control and peripherals. The charger board converts a wall outlet AC signal to a constant current source used to charge the battery pack. The motor control board with inverter drives the 600W motor for the end application and a final board is a Bluetooth® modem that plugs into the battery board for Over-the-Air (OTA) firmware updates, displaying diagnostics and remote control of the system.
