Embodiment Construction

[0033] The present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0034] like figure 1 and Figure 4 As shown, a battery pack suitable for new energy vehicles includes a battery pack casing 12, a battery pack end cover 13 covered on the battery pack casing 12, and a battery pack disposed in the battery pack casing 12. The battery pack includes liquid A cooling and heat dissipation assembly, an air-cooled heat dissipation assembly, and a plurality of battery cells 1 . Each battery cell 1 is a thin plate structure and is arranged side by side. In this embodiment, the battery cell 1 is a common lithium-ion battery.

[0035] See Figure 1-Figure 3 , the battery pack casing 12 has a battery pack mounting cavity 12a for accommodating the battery pack, the cavity wall of the battery pack mounting cavity 12a is provided with a number of component mounting grooves 12b distributed along the circumferential direction, and a...

Abstract

The invention discloses a battery pack suitable for new energy vehicles, which comprises a battery pack shell, a battery pack end cover covered on the battery pack shell, and a battery pack arranged in the battery pack shell. The battery pack includes a liquid-cooled A heat dissipation component, an air-cooled heat dissipation component, and a plurality of electric cores arranged side by side and all of which are thin plate structures. The battery pack suitable for new energy vehicles adopting the above technical solutions has a novel structure, ingenious design, and is easy to implement. Both the liquid cooling component and the air cooling component have greatly improved the heat dissipation effect, which can avoid the overheating problem of the battery pack. Ensure the safety of new energy vehicles and increase the mileage of new energy vehicles.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a battery pack suitable for new energy vehicles. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, mainly electric vehicles. With the promotion of domestic and foreign governments and the technological progress of new energy vehicles, new energy vehicles have been rapidly popularized, and more and more families choose to buy new energy vehicles. [0003] Electric vehicle refers to a vehicle that is powered by on-board power supply and driven by a motor, and meets the requirements of road traffic and safety regulations. Batteries, motors and electronic control systems are the three core and most expensive components of electric vehicles. At present, the biggest problem of new energy vehicles is the cruising range of the battery and the occasional spontaneous combustion accident. Among them, the...
