New energy battery multistage performance detection device

Abstract

The invention discloses a new energy battery multistage performance detection device, belongs to the technical field of battery detection equipment, and is characterized in that the new energy batterymultistage performance detection device comprises a box body, a cover plate is hinged to the top of the box body, a protection shell is fixedly connected to the inner bottom wall of the box body, anda battery body is fixedly connected to the inner bottom wall of the protection shell. A first sliding groove is formed and matched with the a T-shaped rod, so that a closed space is formed between the T-shaped rod and the first sliding groove, expanded air is exhausted through heat dissipation holes of the protective shell along with heat accumulation in the protective shell and heat expansion and cold contraction of air, and air which does not penetrate out of the heat dissipation holes in time enters a detection pipe through the top of a sealing plate; the T-shaped rod is pushed leftwards to drive a connecting plate to move, the top of the connecting plate moves on a standard rod, and the heat dissipation condition in the protective shell can be visually known by reading scales on the surface of the standard rod.

Description

technical field [0001] The invention relates to the technical field of battery testing equipment, more specifically, it relates to a multi-level performance testing device for new energy batteries. Background technique [0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines, including fuel cell vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles, etc., and new energy vehicles generally use new energy batteries as power sources , At present, when enterprises produce new energy batteries, they usually set up a protective shell on the outside to protect the new energy battery. However, when the new energy battery is running, it will generate heat. Generally, the protective shell will be installed Corresponding cooling outlets to release heat, and the cooling capacity of the protective case will directly affect the service life of the new energy battery, so companies often use testing devices to test the cooling capac...

Problems solved by technology

[0003] After searching, the Chinese patent discloses a new energy battery performance detection device (publication number is CN210626627U). The cooperation between a temperature sensor not only detects the temperature inside the normal temperature control box, but also displays the temperature inside the normal temperature control box through the first digital display thermometer. Due to the operation of the hot and cold fans, cold air or hot air will be generated , and the cold air or hot air will enter the inside of the normal temperature control box through the exhaust port, thereby changing the temperature inside the normal temperature control box, making the temperature inside the normal temperature control box close to the normal temperature, thus providing a good solution for the temperature measurement of the protective shell Good external conditions make its temperature measurement effect more accurate, but the device uses a thermometer to reflect the heat dissipation effect of the protective shell is not intuitive enough, and the air tightness of the normal temperature control box is not tested before the measurement. Therefore, the technology in this field Personnel provided a new energy battery multi-level performance detection device to solve the problems raised in the above-mentioned background technology
