Electric vehicle fuel cell test device

Abstract

The invention discloses an electric vehicle fuel cell testing device, which relates to the field of electric vehicle batteries, and comprises a main bottom support plate, the bottom surface of the main bottom support plate is connected with moving rollers by uniform bolts, and the bottom surface of the main bottom support plate is plugged vertically upwards There is a support screw, the bottom end of the support screw is fixedly sleeved with a fixed block, the side of the main bottom supporting plate is horizontally clamped with a toggle plate, and the top surface of the main bottom supporting plate is welded vertically upward with a supporting stand. A fixed cross bar is welded horizontally between the sides of the support vertical bars, and a top fixing plate is horizontally welded on the side between the fixed cross bars, and a side bolt of the support vertical bar is connected with a control main box. The device of the present invention has a simple structure and is easy to operate. It adopts the method of increasing friction to consume the battery, and at the same time, it can simultaneously test multiple groups of batteries at one time, which greatly improves the efficiency of the test, and the structure of the test is more accurate and reliable. authoritative.

Description

technical field [0001] The invention relates to the technical field of electric vehicle batteries, in particular to an electric vehicle fuel cell testing device. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Because the fuel cell converts the Gibbs free energy part of the chemical energy of the fuel into electrical energy through electrochemical reaction, it is not limited by the Carnot cycle effect, so the efficiency is high; in addition, the fuel cell uses fuel and oxygen as raw materials; There are no mechanical transmission parts, so there is no noise pollution and very few harmful gases are emitted. It can be seen that from the perspective of saving energy and protecting the ecological environment, fuel cells are the most promising power gen...

Problems solved by technology

[0004] The purpose of the present invention is to provide electric vehicle fuel cell testing device, to solve the traditional side view to the fuel cell proposed in the above-mentioned background technology is to use the rotation of the driving wheel, then check the number of kilometers the driving wheel rotates, and simultaneously according to the fuel cell The energy loss of the battery is used to judge the energy efficiency of the battery. Because electric vehicles have different power consumption conditions caused by different resistances when driving on the road, this test method is not convincing, and the test equipment can only test a single battery at a time. The test results in low efficiency of the test, and the large volume brings inconvenience when carrying and moving. When the rotation is performed, there will be noise along with the vibration, which will affect the nearby staff to perform other operations.
