Lamination heat plate based on electric heating, and electric heating system for lamination heat plate

Abstract

A lamination heat plate based on electric heating is disclosed. The lamination heat plate is provided with a lamination zone for placing a module, and a heat preservation zone at the edge; a plurality of electric heating elements and temperature sensors that are evenly arranged are provided in the lamination zone and the heat preservation zone respectively, and the number of the electric heating elements is more than that of the temperature sensors; and the electric heating elements and the temperature sensors are respectively electrically connected to heating controllers. The disclosure can effectively ensure the overall temperature uniformity of the lamination heat plate in the lamination process, and can solve the problem of uneven temperature between the edge of the lamination heat plate and the middle portion where the module is placed caused by conventional oil heating. Therefore, the heating method of the disclosure has advantages of high accuracy of temperature control, high heating speed, energy saving or the like, and can improve the productivity of the laminating equipment and the yield rate of battery modules. An electric heating system for a lamination heat plate is further disclosed.
