Abstract
Methods and systems are provided for managing multi-battery systems, such as those utilized in an electric vehicle. Multi-battery systems comprise batteries providing power in parallel, thereby making each battery available to the vehicle and avoiding the weight of transporting a backup battery. The methods and systems provided allow for a fault in one battery, in a parallel configuration with at least one other battery, to be detected and managed.
Claims21
1-20. (canceled)
A system, comprising:
- a main controller that generates and sends, upon determining that first sensor data from a first battery sensor monitoring an attribute of a first battery indicates a fault with the first battery, a first control signal to a first battery switch to isolate the first battery from a load while maintaining uninterrupted power to the load with a second battery during a period of time in which the first battery switch is switched to isolate the first battery from the load, the second battery being connected in parallel with the first battery.
A system, comprising:
- a main controller that:
- generates and sends, upon determining that first sensor data from a first battery sensor monitoring a first attribute of a first battery indicates a fault with the first battery, a first control signal to a first battery switch to isolate the first battery from a load while maintaining interrupted power to the load with the second battery during a period of time in which the first battery switch is switched to isolate the first battery from the load, the second battery being connected in parallel with the first battery;
- and
- generates and sends, upon determining that second sensor data from a second battery sensor monitoring a second attribute of a second battery indicates a fault with the second battery, a second control signal to a second battery switch to isolate the second battery from the load while maintaining uninterrupted power to the load with the first battery during a period of time in which the second battery switch is switched to isolate the second battery from the load.
1 more element
A method, comprising:
- monitoring an attribute of a first battery coupled to a load;
- and
- generating and sending, upon determining that the monitored attribute of the first battery indicates a fault with the first battery, a first control signal to a first battery switch to isolate the first battery from the load while maintaining uninterrupted power to the load with a second battery during a period of time in which the first battery switch is switched to isolate the first battery from the load, the second battery being connected in parallel with the first battery.
