Summary:

To avoid damage and maximize capacity, the voltages of the individual batteries in series connected packs should be equalized. Long term trickle charging is the traditional equalization method, but this is inconvenient for EVs and HEVs. Electronic equalizers also can be used to redistribute the charge amongst the batteries so that trickle charging is no longer necessary. A new type of high frequency electronic equalizer called the ramp converter uses soft switching techniques and a unique transformer design to minimize size and cost. Experimental results at two different power levels indicate performance similar to trickle charging but with a much shorter charging time
