RoboteQ’s BMS10x0x is a battery management and protection system for building cost-effective, ultra-efficient and high current power sources using Lithium battery cells.


The BMS connects to an array of battery cells at one end, and to a user load at the other. Available in a 40V, 60V and 75V versions, it is optimized for 6-cell to 15-cell battery packs.

Precision voltage sensors monitor the voltage of every cell. Precise, built-in current sensors keep track of the current flowing in and out of the pack, load and charge, maintaining an accurate image of the battery’s State of Charge and State of Health. Balancing takes places during battery charge.

The BMS includes a separate connector for battery charging. The charger’s voltage and current are monitored and an internal switch will automatically stop the charging when the battery is full or if a fault condition occurs. This allows the load to be controlled separately.

The BMS10x0x supports regenerative loads, such as motor controllers in electric vehicles or mobile robot application. A built-in, bidirectional, high power solid-state switch will disconnect the regenerative current source from the cells in case the later are fully charged and cannot accept more current. A secondary, built-in high power switch will connect the auxiliary power port to an optional external brake resistor, in case of braking while the batteries are full.

Charge/discharge current, voltages, internal and battery temperatures are continuously monitored. The internal switch will disconnect the load in case of overload, over or under voltage, or over temperature. The BMS will act as a programmable circuit breaker in case of a short circuit or continuous overload. The BMS is highly configurable: temperature limits, voltage thresholds, and current overload levels can all be set and changed using a provided PC Utility. The utility can also be used to view and chart in real time the BMS internal parameters while the system is running. This provides the user with useful data during system development and tuning.

State of Charge, voltage, current, temperature and other vital parameters are available on a front connector using selectable communication methods. This includes USB, CANbus, RS485 and PWM, or wirelessly via an optional Bluetooth module. A push button and LEDs are also provided for quick visualization of battery charge level and system status.
