Abstract
The present method for indicating a battery state of a hybrid car detects ΔV/ΔI which is a change value of voltage and current from a first state and a second state of a battery 1 being charged/discharged. The battery state indicating method determines whether the battery is charged/discharged in a battery protective state based on the ΔV/ΔI and indicates that the battery protective state is established when the battery is charged/discharged in a protective state.
Claims22
A method for indicating a battery state of a hybrid car, the method comprising the steps of:
- detecting ΔV/ΔI which is a change value of voltage and current from a first state and a second state of a battery being charged/discharged;
- and
- determining whether charging/discharging is performed in a battery protective state based on the ΔV/ΔI, and indicating that the battery protective state is established when charging/discharging is performed in the protective state.
An apparatus for indicating a battery state of a hybrid car, the apparatus comprising:
- a determination circuit for detecting ΔV/ΔI which is a change value of voltage and current from a first state and a second state of a battery being charged/discharged;
- and
- a display for indicating that the battery protective state is established when the determination circuit determines that charging/discharging is performed in the protective state.
