Problems solved by technology

In addition, some car companies also provide PTC heating systems and other solutions for heating the power battery in winter. Although it can maintain the temperature of the power battery, it also consumes part of the battery power.
Although these methods alleviate the impact of temperature on the power battery of electric vehicles to a certain extent and improve the safety of driving, they still cannot change the impact of the ambient temperature of the power battery on the battery life and the safety of the power battery after the electric vehicle is hit by other vehicles. During the use of electric vehicles, electric vehicles still face unknown problems such as battery life attenuation in winter, spontaneous combustion of power batteries in summer, shortened service life, squeeze damage of power batteries when the vehicle is hit, and short-circuit fires.

Embodiment Construction

[0015] The main idea of ​​the present invention is to provide a fully sealed electric vehicle power battery container with temperature adjustment equipment and isolated from external temperature exchange, which is convenient for the electric vehicle to independently balance the temperature of the power battery compartment in a low or high temperature environment, creating a 15-25°C temperature microenvironment suitable for power battery work. It consists of two parts, the power battery compartment for accommodating the power battery and the control compartment for controlling the ambient temperature of the battery compartment. Among them, the power battery compartment contains major equipment such as shockproof battery racks, power batteries, battery compartment temperature sensing devices, and temperature-conducting air pipes, which are mainly used to maintain the ideal ambient temperature of the power battery compartment, so that the power battery can drive the car in an exte...

Abstract

The invention discloses a power battery packaging bag with autonomous constant temperature and shockproof functions for an electric vehicle, which is used for isolating temperature exchange between a power battery of the electric vehicle and the outside and maintaining the environment temperature of the power battery within the range of 15-25 DEG C in a temperature slow-release manner so as to reduce the problems of battery endurance attenuation in winter and the like. The power battery cabin is used for accommodating a power battery and a shockproof battery rack and is provided with a temperature sensing device and a temperature conducting air pipe, and the control cabin comprises a temperature management system, a temperature storage barrel filled with temperature bearing liquid and internally provided with a heating device, a condenser, a compressor, various valves and an air pump device. In the temperature range of-40 DEG C to 180 DEG C, the temperature opposite to the ambient temperature is loaded and stored in the temperature bearing liquid, and the temperature is automatically and slowly released to the battery cabin through the temperature conducting air pipe according to the requirement, so that the battery cabin is always kept at the optimal working temperature of 15-25 DEG C. Meanwhile, the packaging bag also has the functions of heating or conveying cold air to passenger cabins and passenger carrying cabins in the vehicle or seats and steering wheels in the vehicle, and has the functions of collision prevention, shock prevention, battery fire suppression by inert gas and the like.

Description

technical field [0001] The invention relates to a power battery packaging package for an electric vehicle with an independent constant temperature and shockproof function, which belongs to the technical field of automobiles. The relatively constant temperature micro-environment with vibrating driving, which is conducive to power battery storage and discharge, minimizes the impact of external high and low temperature environments on power battery storage and discharge, and even the mileage of electric vehicles. The car's power battery provides a relatively safe protective shell. Background technique [0002] With the advancement of transportation technology, the automobile industry has also ushered in the transformation and development from fuel vehicles to new energy vehicles, and the development of electric vehicles is particularly rapid. In order to shorten the gap between the mileage of electric vehicles and fuel vehicles as soon as possible, various car companies contin...
