| 20110260779 | CURRENT BALANCING DEVICE FOR PARALLEL BATTERIES AND CONTROL METHOD THEREOF - A current balancing device for parallel batteries is electrically connected with a load. The current balancing device includes a buck module, a normal module, a current comparing module and a control module. The buck module is electrically connected with a high voltage battery and outputs a first current to the load. The normal module is electrically connected with a low voltage battery and outputs a second current to the load. The current comparing module is electrically connected with the buck module and the normal module, and compares the first current with the second current to output a first comparing signal. The control module is electrically connected with the buck module and the current comparing module, and outputs a control signal to the buck module in accordance with the first comparing signal for adjusting the first current. | 10-27-2011 |
