Abstract
A universal adaptive battery charger is provided. The adaptive battery charger includes a USB power input, an adaptive output circuitry, preconfigured charging profiles, multi-chemistry support, and safety protections. The bi-directional power flow capability also facilitates use of the adaptive battery charger as a DC-to-DC charger for USB fast charging using normative or extended power voltage power delivery protocols.
Claims20
An adaptive battery charger comprising:
- a terminal connector configured to at least one of deliver an output power or to receive an input power;
- a USB connector configured to at least one of deliver the output power or to receive the input power;
- a power control circuit configured to (i) receive the input power, (ii) and negotiate power delivery between the terminal connector and the USB connector;
- a battery charging circuit configured to (i) receive the input power from the power control circuit and deliver the output power, and (ii) execute one or more safety check workflows prior to delivering the output power;
- a sensing circuit configured to (i) sense the input power via the power control circuit and one or more battery parameters via the battery charging circuit, and (ii) output sensor data corresponding to the input power and the one or more battery parameters;
- and
- a controller configured to (i) receive the sensor data, (ii) generate one or more commands based on the sensor data, and (iii) output the one or more commands to the power control circuit and the battery charging circuit to control delivery of the output power to charge an output device.
