A battery, a battery module, a battery pack, and an electric vehicle. The battery includes a housing, end covers, partition plates, and a number of electrode core assemblies. The end covers are arranged on two opposite ends of the housing for sealing an internal space of the housing. The partition plates are spaced apart from each other in the housing for separating the internal space of the housing into a number of accommodating cavities successively arranged along a first direction. Each electrode core assembly is arranged in each accommodating cavity. The electrode core assembly includes at least one electrode core. The number of electrode core assemblies are successively arranged along the first direction and connected in series. The partition plate is provided with an electrolyte solution filling channel. The electrolyte solution filling channel is in communication with the accommodating cavity on at least one side of the partition plate, and is configured for electrolyte solution to be filled into the accommodating cavity from an outside of the battery. The electrolyte solution filling channel is in a closed state upon completion of the electrolyte solution filling, to prevent communication between the accommodating cavity and the outside of the battery. A through hole is provided at a position of the housing corresponding to the electrolyte solution filling channel on the partition plate.
