Abstract
A device and method for charging a battery pack may include one or more charger terminals configured to connect to corresponding one or more battery pack terminals of a battery pack. The device may include a sensor configured to measure a movement of the charger. The device may include a controller electrically coupled to the sensor and configured to: receive, from the sensor, a movement parameter of the battery pack charger, determine a derating value based on the movement parameter, and modify an amount of current provided to the battery pack over the one or more terminals based on the derating value.
Claims20
A battery pack charger comprising:
- one or more charger terminals configured to connect to corresponding one or more battery pack terminals of a battery pack;
- a sensor configured to measure a movement of the battery pack charger;
- and
- a controller electrically coupled to the sensor and configured to:
- receive, from the sensor, a movement parameter of the battery pack charger,
- determine a derating value based on the movement parameter, and
- modify an amount of current provided to the battery pack over the one or more charger terminals based on the derating value.
A method of charging a battery pack with a battery pack charger, the method comprising:
- receiving, from a sensor at a controller of the battery pack charger, a movement parameter of the battery pack charger;
- determining, using the controller, a derating value based on the movement parameter;
- and
- modifying, using the controller, an amount of current provided to the battery pack based on the derating value.
A battery pack charging system comprising:
- a first charger configured to receive a first type of battery pack;
- a second charger configured to receive a second type of battery pack;
- a sensor configured to measure a movement of the battery pack charging system;
- and
- a controller electrically coupled to the sensor and configured to:
- receive, from the sensor, a movement parameter of the battery pack charging system,
- determine a derating value based on the movement parameter, and
- modify an amount of charging current provided via the first charger and the second charger based on the derating value.
