Energy-saving and heat preservation electric vehicle heating chamber and heating method

Abstract

The invention discloses an energy-saving and heat preservation electric vehicle heating chamber and a heating method. The electric vehicle heating chamber comprises a chamber housing, a telescopic base, a flow guiding bottom pipe, a vacuum bottom pad, a fixed hanging box and a heat preservation plate, wherein the telescopic base is movably installed at the bottom of the chamber housing, the telescopic base and the chamber housing are butted and fixed through telescopic rods, the upper part of the telescopic base is sleeved with a combined clamping frame, the combined clamping frame is composedof an arc-shaped side groove and a push-pull clamping strip, the push-pull clamping strip is movably installed on the outer surface at one side of the combined clamping frame, the combined clamping frame is butted and fixed with the telescopic base through the push-pull clamping strip, and the arc-shaped side groove is arranged at the front part of the combined clamping frame. According to the energy-saving and heat preservation electric vehicle heating chamber and the heating method, a uniform heating operation can be performed on batteries in the heating chamber, the utilization rate of heat energy is improved, and a role of energy saving is played. Meanwhile, the heat preservation effect of the heating chamber is effectively improved, the temperature loss is avoided, and the application range of the heating chamber is expanded.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, in particular relates to a heating cavity of an electric vehicle, and more specifically relates to an energy-saving and heat-preserving heating cavity of an electric vehicle and a heating method. Background technique [0002] The electric vehicle heating chamber is a kind of equipment for heating the battery of the electric vehicle in a low temperature environment, which can prolong the service life of the battery. Under the driving mileage, the depth of discharge of the battery using fuel heating is lower than that of using electric heating. According to the characteristics of lithium batteries, the battery life depends on the depth of discharge. The lower the depth of discharge, the battery can be charged and discharged. There is a certain relationship between the service life of the battery and the depth of discharge; [0003] The existing electric vehicle heating cavity has certain...

AI Technical Summary

Problems solved by technology

[0003] The existing electric vehicle heating cavity has certain disadvantages during use. The traditional electric vehicle heating cavity only has a single-layer insulation structure, so that when the electric vehicle heating cavity is heating, part of the heat in the electric vehicle heating cavity will be released. leakage, resulting in a certain energy loss and poor energy-saving effect. The traditional electric vehicle heating chamber adopts a single-layer heat conduction structure, which makes the battery in the electric vehicle heating chamber not heated evenly, thus increasing the time required for electric vehicle battery heating. Traditional The integrated structure of the electric vehicle heating cavity makes the electric vehicle heating cavity only suitable for a single model, which reduces the scope of application of the electric vehicle heating cavity and brings certain adverse effects to users
