Abstract
Systems and methods related to redundant battery management systems (BMS) may include an on-battery BMS, and one or more off-battery, off-vehicle, and/or remote BMS. The one or more remote BMS may receive data associated with parameters of a battery, and may process the received data using various models, algorithms, or estimators to determine a battery state. The battery state determined by the remote BMS may then be used to corroborate or support a battery state determined by the on-battery BMS, thereby ensuring safe, reliable, and efficient operations of systems, machines, or devices utilizing batteries as power sources.
Claims20
A method, comprising:
- selecting, by a controller, an off-battery battery management system (BMS) to which to transmit parameter data associated with a battery of a system;
- transmitting, by the controller, the parameter data to the selected off-battery BMS;
- receiving, by the controller, an off-battery battery state determination from the selected off-battery BMS;
- receiving, by the controller, an on-battery battery state determination from an on-battery BMS:
- determining, by the controller, a battery state based at least in part on the off-battery battery state determination and the on-battery battery state determination;
- and
- causing operation, by the controller, of the system based at least in part on the determined battery state.
An aerial vehicle, comprising:
- a body;
- at least one propulsion mechanism;
- a battery having an associated on-battery battery management system (BMS), the on-battery BMS configured to calculate an on-battery battery state determination based at least in part on parameter data associated with the battery;
- and
- a controller configured to at least:
- select an off-battery BMS to which to transmit parameter data;
- transmit the parameter data to the selected off-battery BMS;
- receive an off-battery battery state determination from the selected off-battery BMS;
- receive the on-battery battery state determination from the on-battery BMS;
- determine a battery state based at least in part on the off-battery battery state determination and the on-battery battery state determination;
- and
- cause operation of the aerial vehicle based at least in part on the determined battery state.
A computer-implemented method to monitor a battery of a vehicle, comprising:
- receiving, by a controller, parameter data associated with the battery;
- determining, by the controller, to transmit the parameter data to at least one of a plurality of off-battery battery management systems (BMS);
- selecting, by the controller, an off-battery BMS to which to transmit the parameter data;
- transmitting, by the controller, the parameter data to the selected off-battery BMS;
- receiving, by the controller, an off-battery battery state determination from the selected off-battery BMS;
- receiving, by the controller, an on-battery battery state determination from an on-battery BMS:
- processing, by the controller, the off-battery battery state determination with the on-battery battery state determination;
- determining, by the controller, a battery state based at least in part on the off-battery battery state determination and the on-battery battery state determination;
- and
- causing operation, by the controller, of the vehicle based at least in part on the determined battery state.
