Electromagnetic induction heating battery high-vacuum baking single furnace

Abstract

The invention discloses an electromagnetic induction heating battery high-vacuum baking single furnace. The electromagnetic induction heating battery high-vacuum baking single furnace comprises a vacuum furnace body, a plurality of electromagnetic induction heating assemblies which are sequentially stacked in the vertical direction are arranged in the vacuum furnace body, a plurality of battery clamps are placed on each electromagnetic induction heating assembly, a battery placing bottom plate of each battery clamp is made of metal, a plurality of batteries are placed on the battery placing bottom plates, the electromagnetic induction heating assemblies perform electromagnetic heating on the battery placing bottom plates, and then the battery placing bottom plates transmit heat to the batteries. The battery placing bottom plates of the battery clamps are heated in an electromagnetic induction heating mode, and then transfer the heat to the batteries for baking the batteries, the heating mode is uniform in heating and high in temperature rising speed, the temperature of the batteries can be raised to 90 DEG C within 3 minutes, the heating efficiency is greatly improved, and the requirements of people for high efficiency are met.

Description

technical field [0001] The invention relates to the technical field of lithium battery production and processing equipment, in particular to an electromagnetic induction heating battery high-vacuum baking monomer furnace.

With the shortage of energy and the pressure of the world's environmental protection, lithium batteries are widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate ...

AI Technical Summary

Problems solved by technology

[0003] The existing lithium battery preheating and baking is realized through the existing heating single furnace, and the existing heating single furnace is generally heated by a resistance heating plate, but the above heating methods have the following disadvantages: Disadvantages: 1. The heating efficiency is slow. For example, it takes 2 hours to heat the lithium battery to 90°C by using a resistance heating plate, which is far from meeting people's high efficiency needs; 2. Large energy consumption, resistance heating energy The conversion rate is only 35%; 3. The equipment occupies a large area and the utilization rate of the plant is low; 4. The resistive heating plate is set on the battery fixture, resulting in many connections of the battery fixture, complicated process and high maintenance cost
