Abstract
The invention discloses a stacked battery system integrated with a water cooling structure, relates to the technical field of new energy electric vehicles, and provides the following scheme aiming atthe problems that the integration degree of an existing battery is relatively low, the structure is complex, the acceptance and installation man-hour cost of a single water cooling plate is relativelyhigh, and the risk of water leakage caused by connection of multiple adapters is high. The stacked battery system comprises a plurality of lower box bodies arranged in a stacked mode, a main controlbox MCU and a high-voltage control box BDU are arranged in the lower box bodies, a heating system PTC is arranged on one side of the main control box MCU and one side of the high-voltage control box BDU, a module is arranged above the heating system PTC, a copper bar is arranged on the left side of the module, and an upper box cover is arranged above the module; a water cooling cover plate is arranged at the bottom of the lower box body, and a water cooling system is arranged in the lower box body. The whole device disclosed by the invention can be randomly combined and stacked by a pluralityof battery systems, meets various capacity requirements, and is extremely convenient to assemble and disassemble.
Description
technical field [0001] The invention relates to the technical field of new energy electric vehicles, in particular to a battery system with a stacked integrated water cooling structure. Background technique [0002] The power battery is a key component of new energy electric vehicles, and the battery box is the first layer of mechanical protection for the entire battery system. As the core component of the battery system of new energy electric vehicles, the shell can accommodate and protect the battery cells, copper bars, electrical components, etc.; externally, it can be directly connected and fixed with new energy electric vehicles. At present, the battery box on the market is formed by sheet metal bending, tailor welding or stamping; or extruded aluminum friction stir welding. , the sheet metal box has defects such as many welds, easy to leak, easy to deform when welding, and deviations in installation dimensions. The production efficiency is not too high, and there may ...
