15S Battery Cell Monitor & Balancer - in development
15S Battery Balancer PCB
The 15S Battery Cell Monitor & Balancer is a precision instrument that ensures that multi-cell batteries are maintained in an optimal state, improving system reliability and prolonging battery life.
The 15S Battery Cell Monitor & Balancer does exactly as its name suggests: it monitors cells within a battery, and it balances those cells if and when they require it. Comprehensive data detailing the battery’s internal state is sent via the CAN interface.
Transforms a "dumb" battery into a smart (self-balancing) battery.
Supports multiple battery chemistries - LiPo, LiS and LiFe.
Supports 9 to 15S batteries.
Galvanically isolated 80 Amp current sensor.
CAN interface provides control and monitoring of voltages, currents, temperatures.
Battery temperature monitoring with up to 3 external sensors.
The Battery Balancer is intended to be connected to a battery, installed into a UAV and interfaced to the vehicle's CAN bus. A pair of indicator lights on the front panel give a "go / no go" indication of the battery's state of balance and state of charge. More detailed battery information is available via the CAN bus.
Use of the battery balancer confers a number of operational advantages:
Batteries do not need to be removed periodically to check for balance.
Battery status is available instantly, either directly from the front-panel LEDs, or remotely from the telemetry data sent on the CAN bus.
Batteries are maintained in a state of balance, improving flight-readiness.
