Abstract

When a heating system comprises an electromagnetic external heating device and a high-frequency internal heating device, the electromagnetic external heating device is based on an electromagnetic heating principle, the heating mode can be understood as an external heating mode, and the high-frequency internal heating device is based on a high-frequency alternating-current internal heating principle. The heating mode can be understood as an internal heating mode, so that by combining the external heating mode and the internal heating mode, the heating efficiency can be improved, the battery pack in the battery device can be rapidly heated, and the cruising ability of electric equipment is improved on the basis of improving the performance of the battery device.

Description

technical field [0001] The present invention relates to the technical field of batteries, in particular to a battery device, a heating method and electrical equipment thereof. Background technique [0002] Due to the reduced activity of the power battery in a low temperature state (ie, a lower ambient temperature), the battery capacity and performance of the power battery in a low temperature state are seriously attenuated, and this attenuation is irreversible, which causes the new energy vehicle to continue its battery life. The mileage has been severely reduced, resulting in a serious reduction in the cruising range. [0003] In order to avoid the above situation, the power battery can be heated at low temperature to avoid serious attenuation of battery capacity and performance. Then, how to heat the power battery is a technical problem to be solved urgently by those skilled in the art. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a ba...
