Abstract
The invention relates to a method for in-place diagnosis of a rechargeable electric vehicle battery, comprising the following steps: discharging the battery in a motor of the vehicle, using an internal resistance of the motor as a resistive load; measuring parameters of the battery during discharge to establish a state of health of the battery; estimating the temperature of the motor during discharge; and regulating the discharge current to stabilize the temperature of the motor at a constant admissible threshold.
