The equalizer measures the voltage of each of the batteries of the string and then closes a switch in the shunt path associated with the highest voltage battery for a predetermined time. Then the switches of all of the shunt paths are opened and the cycle repeats. In this way, charging is equalized in the batteries of the string, regardless of whether or not any of the batteries of the string is in an over charged condition. | InventorAssigneeApplicationNo. 750806 filed on 12/28/2000US Classes:320/122Bypassable battery cellField of Search320/116, SERIALLY CONNECTED BATTERIES OR CELLS320/117, Switchable to parallel connection320/118, With discharge of cells or batteries320/120, Having variable number of cells or batteries in series320/122Bypassable battery cellExaminersPrimary: Tso, Edward H.Attorney, Agent or FirmUS Patent References3237078, 4238721, System and method for charging electrochemical cells in seriesIssued on: 12/09/1980 Inventor: DeLuca , et al.4242627, Battery charger Issued on: 12/30/1980 Inventor: Kisiel4303877, Circuit for protecting storage cells Issued on: 12/01/1981 Inventor: Meinhold5479083, Non-dissipative battery charger equalizer Issued on: 12/26/1995 Inventor: Brainard5504415, Method and apparatus for automatic equalization of series-connected batteries Issued on: 04/02/1996 Inventor: Podrazhansky, et al.5710504, Switched capacitor system for automatic battery equalization Issued on: 01/20/1998 Inventor: Pascual, et al.5821733, Multiple cell and serially connected rechargeable batteries and charging system Issued on: 10/13/1998 Inventor: Turnbull5905360, Battery system and electric motor vehicle using the battery system with charge equalizing features Issued on: 05/18/1999 Inventor: Ukita5932932, Storage battery voltage control apparatus Issued on: 08/03/1999 Inventor: Agatsuma, et al.5956241, Battery cell equalization circuit Issued on: 09/21/1999 Inventor: LoCascio5982050, Power supply unit for automotive vehicle Issued on: 11/09/1999 Inventor: Matsui5982144, Rechargeable battery power supply overcharge protection circuit Issued on: 11/09/1999 Inventor: Johnson, et al.6008623, Charge equalizer or series of connected battery strings Issued on: 12/28/1999 Inventor: Chen, et al.6046573, System for equalizing the level of charge in batteries Issued on: 04/04/2000 Inventor: Wikstrom6064178, Battery charge balancing system having parallel switched energy storage elements Issued on: 05/16/2000 Inventor: Miller6104164, Cell voltage detecting device for combination battery Issued on: 08/15/2000 Inventor: Iino, et al.6114835, Multi-cell battery pack charge balancing circuit Issued on: 09/05/2000 Inventor: Price6121751, Battery charger for charging a stack of multiple lithium ion battery cells Issued on: 09/19/2000 Inventor: Merritt6140800Autonomous battery equalization circuit Issued on: 10/31/2000 Inventor: Peterson International ClassH01M 010/44 |
