<p>An accumulator battery equalizer and an energy balance accumulator battery are provided, belonging to technical field of secondary battery. The equalizer is equipped between the plates of individual battery cell, at least two of which are connected in series so as to compose an accumulator battery set. The equalizer is comprised of a positive pole connected with the positive plate of individual battery cell, and a negative pole connected with the negative plate of individual battery cell. The equalizer is a voltage and current dividing circuit, in which positive direction voltage of the equalizer is greater than the actual highest voltage of individual battery cell and lower than charging voltage of it. A energy balance accumulator battery using the accumulator equalizer is also provided, in which the equalizer is connected in parallel with the individual battery cell. The present invention can prevent battery overcharge and overdischarge effectively, ensure the energy balance between individual battery cells through long-term usage, and improve the useful life greatly.</p> |
