摘要： The present invention is directed to battery systems. In various embodiments, the present invention provides a battery system having a first battery group and a second battery group. The first battery group and the second battery group can share a single housing, or be positioned within separate housings. The first battery group and the second battery group can each have a plurality of cells configured in parallel, and the two groups can be electrically integrated. When operating at a low temperature, the first battery group is configured to provide electrical energy to a heating module that selectively heats up one or more segments of the second battery group. In addition, the first battery group also provides energy for initial operation of an electric vehicle or equipment. Once the selected segments of the battery group are heated up to an operating temperature, the selected segments supply electrical power to the vehicle or equipment and charge the first battery group. In addition, the selected segments of the second battery group provide electrical energy for heating other segments of the second battery group. There are other embodiments as well.

摘要： Provided are battery packs and interface modules for electrically interconnecting electrochemical cells in the packs and for providing heat distribution with the packs. An interface module interfaces one side of all electrochemical cells in a battery pack. The interface module may have a substantially planar shape such that the space occupied by the module in the battery pack is minimal. Most, if not all, conductive components of the interface module may be formed from the same sheet of metal. In some embodiments, the interface module includes multiple bus bars such that each bus bar interconnects two or more terminals of different electrochemical cells in the battery pack. Each bus bar may have a separate voltage sense lead extending from the bus bar to a connecting portion. The bus bars may be flexibly supported within the module. The interface module may also include multiple thermistors disposed on different bus bars.

摘要： Various embodiments herein provide methods and apparatus for conditioning a battery. The conditioning may be undertaken to restore charge capacity or power capability, especially when practiced on a battery having a lithium negative electrode and/or a positive electrode having a conversion material. In one embodiment, the conditioning method includes applying a substantially constant current or power until a conditioning voltage is reached, where the conditioning voltage is higher than the maximum voltage used during normal cycling. The method further includes continuing to charge the battery at the conditioning voltage until a maximum conditioning charge is reached. Next, the method includes discharging the battery to about the maximum charge voltage prior to using the battery in an end use. Also provided is a conditioning apparatus that is configured to perform the conditioning method.
