Device and method for equalizing charges of series-connected energy stores |
摘要 |
A device and method for equalizing the charges of series-connected individual cells of an energy storage device with a DC/DC converter, which draws energy from the energy storage device or from another energy source, charges an intermediate circuit capacitor whose voltage is inverted in a DC/AC converter, converts the alternating voltage via AC bus lines and coupling transformers by way of a rectifier into a pulsating direct current, and charges the cell having the lowest cell voltage with the pulsating direct current.
