Abstract
A battery controller includes an auxiliary measurement energy-storing component, a control unit, a measuring unit and a protection unit. The auxiliary measurement energy-storing component is coupled in series to a battery module outside the controller, and configured to provide an open-circuited voltage. The control unit is configured to output a power value of the battery module according to the open-circuited voltage or a value of current flowing through the battery module. The measuring unit is configured to measure the current flowing through the battery module and transmit the measuring result to the control unit. The protection unit is configured to limit the value of current measured by the measuring unit to a predetermined value. A battery level measurement method of the battery controller is also disclosed.
