Problems solved by technology

[0003] The choice restrictions brought to users by the existing planned electric vehicle platform are mainly reflected in the mileage and price. Although the platform concept of platform modularization saves a lot of development costs and shortens the research and development cycle, it also solidifies the The basic characteristics of the electric vehicles produced by the platform have not yet solved the core problems that users respond to when using pure electric vehicles, such as long charging time and short cruising range, which also limits the further development of pure electric vehicle ownership. promote
In addition, the cost allocated through platformization does not make the price of pure electric vehicles on the same level as traditional vehicles of the same level

Abstract

The invention relates to the technical field of power battery mounting platforms, and discloses a power battery compatible platform and an electric vehicle. The platform comprises: a front end face placing position used for placing the front end face of a power battery; a vehicle body floor which comprises a floor body and threshold beams arranged on the two sides of the floor body, wherein the floor body is provided with a plurality of first fixing point positions, and the threshold beams are provided with a plurality of second fixing point positions; a plurality of third fixing point positions and a plurality of fourth fixing point positions; a high-voltage topological structure which comprises a high-voltage distribution box, wherein the power battery is provided with a high-voltage interface, and the high-voltage interface is connected with the high-voltage distribution box; and a heat management system which comprises a heating system, a battery heat management loop and an air conditioner heat management loop, wherein the heating system is coupled with the battery heat management loop through a first heat exchanger, the heating system achieves coupling switching with a passenger compartment and the battery heat management loop through a three-way valve, the battery heat management loop is coupled with the air conditioner heat management loop through a second heat exchanger, and the air conditioner heat management loop can also be coupled with the passenger compartment.

Description

technical field [0001] The invention relates to the technical field of a power battery installation platform, in particular to a power battery compatible platform and an electric vehicle. Background technique [0002] Judging from the current development status of pure electric vehicles, the technical routes of most OEMs are gradually converging, and the development direction is based on the platform concept of a certain brand platform with power batteries as the core. The difference lies in the range of wheelbase and mileage covered. The main target user group is private users. At present, it does meet the basic car needs of private users, but it does not meet all the needs of private users. [0003] The choice restrictions brought to users by the existing planned electric vehicle platform are mainly reflected in the mileage and price. Although the platform concept of platform modularization saves a lot of development costs and shortens the research and development cycle, ...
