Method of equalizing the voltage across drive batteries for electric vehicles, connected in series during recharging, and a device for implementing the method

摘要

In order to equalize the voltages of batteries ( 1 to n) connected in series during recharging, the voltage (V₁ to Vn) and the temperature (T₁ to Tn) of each battery are measured and only the battery with the lowest voltage is charged with higher-intensity current, a current bypass being applied to the other batteries; the steps are repeated until all the batteries (1 to n) have reched the same voltage in relation to the temperature measured.
