<p>A battery system comprises 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, where 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.</p> |
