Abstract
In some examples, an apparatus is to adjust charge termination voltage. The apparatus includes a controller to adjust a charge termination voltage of a charger of a rechargeable energy storage device based on a comparison of a first threshold level with the voltage of the rechargeable energy storage device during peak load. The charge termination voltage is a voltage at which the rechargeable energy storage device has capacity to support peak load of a system. The controller is to adjust the charge termination voltage based on a comparison of a second threshold level with an end voltage of the rechargeable energy storage device after peak load.
Claims21
An apparatus to adjust charge termination voltage, comprising:
- a controller to:
- increase a charge termination voltage of a charger of a rechargeable energy storage device based on an identification that the voltage of the rechargeable energy storage device during peak load is at or below a first threshold level, wherein the charge termination voltage is a voltage at which the charger stops charging the rechargeable energy storage device and wherein the charge termination voltage is a voltage at which the rechargeable energy storage device has capacity to support peak load of a system;
- and
- decrease the charge termination voltage based on an identification that an end voltage of the rechargeable energy storage device after peak load is at or above a second threshold level that is higher than the first threshold level;
- wherein peak load is a maximum load on the system.
A method to adjust charge termination voltage, comprising:
- increasing a charge termination voltage of a charger of a rechargeable energy storage device based on an identification that the voltage of the rechargeable energy storage device during peak load is at or below a first threshold level, wherein the charge termination voltage is a voltage at which the charger stops charging the rechargeable energy storage device and wherein the charge termination voltage is a voltage at which the rechargeable energy storage device has capacity to support peak load of a system;
- and
- decreasing the charge termination voltage based on an identification that an end voltage of the rechargeable energy storage device after peak load is at or above a second threshold level that is higher than the first voltage level;
- wherein peak load is a maximum load on the system.
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:
- increase a charge termination voltage of a charger of a rechargeable energy storage device based on an identification that the voltage of the rechargeable energy storage device during peak load is at or below a first threshold level, wherein the charge termination voltage is a voltage at which the charger stops charging the rechargeable energy storage device and wherein the charge termination voltage is a voltage at which the rechargeable energy storage device has capacity to support peak load of a system;
- and
- decrease the charge termination voltage based on an identification that an end voltage of the rechargeable energy storage device after peak load is at or above a second threshold level that is higher than the first threshold level;
- wherein peak load is a maximum load on the system.
