    • 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.
    • 本发明涉及电池系统。 在各种实施例中,本发明提供一种具有第一电池组和第二电池组的电池系统。 第一电池组和第二电池组可共享单个外壳,或者位于分开的外壳内。 第一电池组和第二电池组可以各自具有并联配置的多个单元,并且两组可以电气集成。 当在低温下操作时,第一电池组被配置成向选择性地加热第二电池组的一个或多个段的加热模块提供电能。 此外,第一电池组还提供用于电动车辆或设备的初始操作的能量。 一旦电池组的所选段被加热到工作温度,所选择的段向车辆或设备供电并对第一电池组充电。 此外,第二电池组的所选择的段提供用于加热第二电池组的其它段的电能。 还有其它实施例。
