Abstract
The invention relates to the field of battery charging and preheating devices, in particular to a self-heating internal preheating device for rapid charging of battery modules, including a bottom plate, a battery and an automatic preheating device. Wherein, the battery is fixed on the bottom plate, a hollow battery mandrel is arranged in the center of the battery, and an automatic preheating device is installed in the battery mandrel. The present invention realizes the automatic preheating of the battery by installing an automatic preheating device in the space provided by the battery mandrel in the battery and its characteristics. Compared with the existing external heating method for battery preheating, the present invention This design not only does not affect the overall structure of the battery, but also saves the arrangement of a large number of complicated circuits, so that the battery adopting the preheating device of the present invention will not increase the space required for operation, and is economical and practical. obvious improvement.
Description
technical field [0001] The invention relates to the field of battery charging and preheating devices, in particular to a self-heating internal preheating device for rapid charging of battery modules. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] Under the dual pressure of environmental crisis and energy crisis, new energy electric vehicles are becoming more and more popular in the market. As an energy storage element with high energy density and power density, batteries are widely used as power sources for electric vehicles. However, compared with other types of batteries, lithium-ion batteries have the advantages of high specific energy, long cycle life,...
