Battery system and vehicle

A battery system (20) for an electrically or semi-electrically operated vehicle (10), comprising:

• a first battery module assembly (31) having at least a first battery module (33);
• a second battery module assembly (32) having at least a second battery module (34), the second battery module assembly (32) being spaced from the first battery module assembly (31) such that two footwells (35, 36) are formed between the first and second battery module assemblies (31, 32);
• a conduction housing (40) having a front section mounted on top of the first battery module assembly (31), a rear section mounted on top of the second battery module assembly (32), and an intermediate section (42) extending between the front and rear sections of conduction housing (40) and disposed between the two footwells (35, 36);
• a power electronics housing (60) having power electronics (61) therein;
• a terminal box (50) including at least a first terminal (51) for a first consumer (91);
• first conductors (41) being provided in the conduction housing (40) and electrically interconnect the first battery module assembly (31), the second battery module assembly (32), the first terminal (51), and the power electronics (61), wherein the terminal box (50) is connected to the first conductors (41) in a region adjacent to and below the intermediate section (42) of the conduction housing (40).
