Abstract
In some examples, a control unit is configured to adjust charge termination voltage of a rechargeable energy storage device. The control unit is adapted to charge the rechargeable energy storage device to a charge termination voltage where the rechargeable energy storage device has capacity to support peak load but comes close to a system shutdown voltage after supporting peak load. The control unit is also adapted to increase the charge termination voltage if a voltage of the rechargeable energy storage device is near a system shutdown voltage after supporting peak load.
Claims25
A control unit configured to adjust charge termination voltage of a rechargeable energy storage device, the control unit adapted to:
- charge the rechargeable energy storage device to a charge termination voltage where the rechargeable energy storage device has capacity to support peak load but comes close to a system shutdown voltage after supporting peak load;
- and
- increase the charge termination voltage if a voltage of the rechargeable energy storage device is near a system shutdown voltage after supporting peak load.
A method to adjust charge termination voltage of a rechargeable energy storage device, the method comprising:
- charging the rechargeable energy storage device to a charge termination voltage where the rechargeable energy storage device has capacity to support peak load but comes close to a system shutdown voltage after supporting peak load;
- and
- increasing the charge termination voltage if a voltage of the rechargeable energy storage device is near a system shutdown voltage after supporting peak load.
One or more tangible, non-transitory machine readable media comprising a plurality of instructions that, in response to being executed on at least one processor, cause the at least one processor to:
- charge the rechargeable energy storage device to a charge termination voltage where the rechargeable energy storage device has capacity to support peak load but comes close to a system shutdown voltage after supporting peak load;
- and
- increase the charge termination voltage if a voltage of the rechargeable energy storage device is near a system shutdown voltage after supporting peak load.
A system to adjust charge termination voltage of a rechargeable energy storage device, comprising:
- a charger adapted to charge the rechargeable energy storage device;
- and
- a control unit adapted to:
- send a control signal to the charger to charge the rechargeable energy storage device to a charge termination voltage where the rechargeable energy storage device has capacity to support peak load but comes close to a system shutdown voltage after supporting peak load;
- and
- increase the charge termination voltage if a voltage of the rechargeable energy storage device is near a system shutdown voltage after supporting peak load.
