Abstract
An apparatus is disclosed for parallel charging of at least one power storage unit. In example implementations, an apparatus includes a charging system. The charging system includes a first charger having a first current path and a second charger having a second current path. The charging system also includes a charging controller coupled to the first current path. The charging system further includes an indication path coupled between the second current path and the charging controller.
Claims30
An apparatus for parallel charging, the apparatus comprising:
- a charging system comprising:
- a first charger comprising a first current path;
- a second charger comprising a second current path;
- a charging controller coupled to the first current path;
- and
- an indication path coupled between the second current path and the charging controller.
An apparatus for charging at least one power storage unit, the apparatus comprising:
- a first charger comprising means for propagating a first current;
- a second charger comprising means for propagating a second current;
- first means for indicating the first current;
- second means for indicating the second current;
- means for generating a combined indication signal responsive to the first means for indicating and the second means for indicating;
- and
- means for controlling a charging of the at least one power storage unit based on the combined indication signal.
A method for operating a charging system, the method comprising:
- obtaining a first indication signal indicative of a first current flowing through a first current path of a first charger;
- obtaining a second indication signal indicative of a second current flowing through a second current path of a second charger;
- combining the first indication signal and the second indication signal to produce a combined indication signal;
- and
- controlling the charging system based on the combined indication signal.
An apparatus for parallel charging, the apparatus comprising:
- a charging system comprising:
- a charging voltage node;
- a buck charger comprising a current path;
- a charge pump charger comprising a current path, the current path of the charge pump charger coupled to the charging voltage node;
- a charging controller coupled to the current path of the buck charger;
- and
- an indication path coupled between the charging controller and the current path of the charge pump charger, the indication path configured to provide an indication of a current flowing though the current path of the charge pump charger.
