Claim:
1. A battery system comprising: a first battery group comprising battery cells, wherein the battery cells of the first battery group each comprise liquid electrolyte, the first battery group having a first capacity and operating at a first temperature; a second battery group comprising battery cells, wherein the battery cells of the second battery group each comprise a solid-state electrolyte, wherein the second battery group is an electrically coupled to the first battery group, the second battery group having a second capacity and operating at a second temperature, the second capacity being greater than the first capacity, the second temperature being higher than the first temperature; a first heating module electrically coupled to the first battery group; wherein the first heating module comprises a first thermal path thermally coupled to the battery cells of the first battery group, and a second thermal path including a first thermal segment and a second thermal segment, the first thermal segment being thermally coupled to the first battery group, the second thermal segment being thermally coupled to the battery cells of the second battery group; and a control module programmed to cause the first battery group to power the first heating module to selectively provide heat to the battery cells of the first battery group by the first thermal and the battery cells of the second battery group by the second thermal path.
