First Claim
Patent Images
1. A method for indicating a battery state of a hybrid car, the method comprising the steps of:
- detecting Δ
V/Δ
I 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 Δ
V/Δ
I, and indicating that the battery protective state is established when charging/discharging is performed in the protective state.

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.

13. An apparatus for indicating a battery state of a hybrid car, the apparatus comprising:
-
a determination circuit for detecting Δ
V/Δ
I 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. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
