1. A battery system for a vehicle, the battery system comprising:
multiple battery modules, wherein each battery module comprises one or more battery cells, and wherein each battery module comprises an exhaust port;
one or more structural members mechanically coupled to the multiple battery modules;
at least one upper row of the battery modules, wherein each of the battery modules has a top and a bottom, wherein the exhaust ports are formed in the bottoms of the battery modules, and wherein the tops of the battery modules in the at least one upper row face upward; and
at least one lower row of the battery modules, wherein the at least one lower row of the battery modules is below the at least one upper row of the battery modules, and wherein the tops of the battery modules in the at least one lower row face downward;
wherein the one or more structural members and the multiple battery modules define an exhaust chamber;
wherein the exhaust chamber is in fluid communication with the exhaust ports of the multiple battery modules;
wherein the one or more structural members comprise an outlet port in fluid communication with the exhaust chamber and an exterior of the exhaust chamber;
wherein the one or more structural members comprise at least one first structural member mechanically coupled to at least one battery module in the at least one upper row and at least one battery module in the at least one lower row; and
wherein the at least one first structural member, the at least one battery module in the at least one upper row, and the at least one battery module in the at least one lower row define at least a portion of the exhaust chamber.
