1. A battery system comprising:
- a first battery unit;
a DC voltage bus;
a second battery unit electrically connected to the DC voltage bus;
a current-limiting component; and
switching circuitry for connecting the first battery unit to the DC voltage bus,wherein the switching circuitry is configured to electrically connect the first battery unit to the DC voltage bus either directly or through a current-limiting component, depending on an operating parameter of the first battery unit, wherein the operating parameter is a voltage difference between the first battery unit and the DC voltage bus.
