Problems solved by technology
[0007] The purpose of the present invention is to solve the shortcomings in the prior art, such as: using liquid cooling to dissipate heat, but there will be liquid leakage during long-term use, and there are certain defects in the protection of the battery pack, which is easy to be damaged by bumps and collisions. Vibration is prone to damage, and the protection of the core components of the battery pack is poor, resulting in a short service life, inconvenient installation, and the entire battery assembly needs to be disassembled during disassembly, which is inconvenient in the disassembly process

The invention discloses a new energy vehicle detachable battery pack, which includes a mounting bottom plate. A mounting base is fixedly mounted on the top of the bottom plate, and a battery pack bodyis installed on the top of the mounting base. Battery modules are disposed on both sides in the battery pack body. Hollow separating heat conduction plates are fixedly installed at equal intervals inside each battery module. Three groups of battery pack plates are fixedly installed at each of both sides of each hollow separating heat conduction plate in each battery module through side protectiveplates. The top of each hollow separating heat conduction plate is provided with a thermally conductive separating plate mounting head fixedly connected to the battery module. The new energy vehicledetachable battery pack has the beneficial effects that the heat absorbed by thermally conductive separating plates are transferred by thermally conductive strips, then transferred to the heat conduction plates, and finally dissipated through thermally conductive contact blocks and the heat dissipation blocks to ensure the safety of a heat dissipation process.
Description
technical field [0001] The invention relates to the technical field of batteries for new energy vehicles, in particular to a detachable battery pack for new energy vehicles. Background technique [0002] With the rapid development of my country's economy, people have put forward higher requirements for travel tools. As a new type of transportation, electric vehicles are loved by the public because of their environmental protection and affordable prices. However, the power source of electric vehicles mainly relies on Its battery drives the motor to rotate to drive the car forward, and the battery pack is the core component of the new energy vehicle. [0003] Although the existing patent (notification number: CN 110176567 A) discloses in the field of electric vehicles, especially electric vehicle battery packs, the electric vehicle battery packs include an upper case and a lower case, and the upper case and the lower case The body is combined to form a cavity for accommodating...
