A battery pack includes battery cells arranged in an array to form a battery module layer. Multiple layers are vertically stacked with thermal management devices, such as active heat exchangers in the form of battery cold plates, above and below each layer to form a multi-layer battery stack that may be held in compression by a battery pack frame. The multi-layer battery stack and battery pack frame are surrounded by a battery enclosure, which has flat sealing surfaces to ensure robust sealing. The battery pack is associated with a thermal management system for cooling and heating the battery cells of the battery pack. The battery thermal management system provides cooling and heating by alternating cooling flow directions to achieve uniform temperature distribution. The battery pack may also include a vent detection sensor and vent isolators to detect and mitigate effects of a battery thermal runaway event. Multiple battery packs of a common form factor can be combined in parallel in different arrangements for different vehicles to optimize electric vehicle range, performance, and weight distribution. The battery system can be, charged, discharged, controlled, and thermally managed either by a centralized system or distributed system.
