Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, and in particular to a splicable battery cooling plate assembly and a vehicle having the same. Background Art

[0002] In recent years, with the rapid development of the new energy vehicle industry, the safety of power batteries has always been the focus and difficulty of the industry. The mandatory national standard "Safety Requirements for Power Batteries for Electric Vehicles" GB 38031-2020 issued in 2020 has clear requirements for the performance of battery systems in thermal diffusion: the battery pack or system should provide a thermal event alarm signal 5 minutes before the passenger compartment is in danger due to thermal runaway of a single battery causing thermal diffusion (serving the thermal event alarm of the entire vehicle to remind passengers to evacuate). If the thermal diffusion does not cause danger to the vehicle occupants, the requirement is considered to be met. With consumers paying more and more attention to battery safety and the continuous technological iteration of electric vehicle and battery manufacturers, it is expected that the requirements for thermal diffusion of battery systems will become more and more stringent in the future, such as extending the time for dangerous events to occur, and even requiring that thermal diffusion never occurs.

[0003] As the market share of new energy vehicles continues to increase, how to reduce energy consumption and improve passenger comfort has put higher and higher requirements on vehicle thermal management. Under low temperature conditions, turning on PTC to heat the passenger compartment will consume a lot of electricity, causing the cruising range to continue to decline. In order to solve the problems of increased energy consumption and reduced cruising range at low temperatures, heat pump technology is gradually being promoted in new energy vehicles. However, in ultra-low temperature conditions where the environment is below -15°C, the existing heat pump technology cannot meet the heating needs of the passenger compartment or battery, and needs to rely on PTC heating, which is not conducive to the cost control of the thermal management system; at the same time, the performance and reliability requirements of key components such as PTC are high, which will bring certain quality problems and after-sales risks.

[0004] The thermal management system is the core component of the power battery. Existing power batteries use water cooling with water cooling plates or partially use air cooling, which has the disadvantages of low heating and cooling efficiency, high system complexity, and uneven heating and cooling temperature fields. It is also very inconvenient to install and maintain during the later after-sales period. Utility Model Content
