AI Technical Summary
Existing lithium battery systems are unstable in low-temperature environments and have complex structures, making them unsuitable for modular production and convenient use.
The modularly designed positioning frame and heating film structure includes a vertically arranged positioning frame and heating film. The heating film is automatically adjusted by a control device to maintain the lithium battery temperature within a suitable range. The combination of epoxy resin heating film and graphene heating film improves structural strength and waterproofness.
It enables stable operation of lithium battery systems in low-temperature environments, improves charging efficiency and energy storage stability, while reducing waterproofing costs and improving the cost-effectiveness of the equipment.

Abstract
Claims
1. A lithium battery system with waterproof heating, characterized by, include: The box body has a first opening on its front wall, and the first opening has a pivotally mounted door. The positioning frame has an inner wall of the rear frame of the box. The positioning frame is vertically arranged. The positioning frame includes a rear frame and side plates extending outward from the front wall of the rear frame. The side plates are four in number and overlap each other to form a frame with a second opening at the front end. The frame is equipped with stacked lithium batteries; A heating film is provided between the inner wall of the rear frame and the inner wall of the side plate and the outer peripheral wall of the lithium battery. A control device is located in the upper part of the inner cavity of the box, and the control device is connected to the heating film. When the control device detects that the lithium battery temperature is lower than the lower threshold, the control device controls the circuit switch of the heating film to close, the heating film circuit is turned on, and the heating film starts to heat up. When the control device detects that the lithium battery temperature has reached the upper limit threshold, the control device controls the heating circuit to disconnect. At this time, the conduction circuit of the heating film is disconnected, and heating stops.
2. The lithium battery system with waterproof heating of claim 1, wherein: The rear frame includes two bent rear frames. The bent frame extends from the rear to the side. The side plate includes a top plate, a bottom plate, and two side rods disposed between the top plate and the bottom plate. The bent frame, top plate, bottom plate, and side bars form the positioning frame.
3. The lithium battery system with waterproof heating of claim 1, wherein: The bottom wall of the box is provided with a lifting frame, and the positioning frame is mounted on the lifting frame.
4. The lithium battery system with waterproof heating of claim 2, wherein: Clearance slots are provided between adjacent bending frames and between bending frames and side bars.
5. The lithium battery system with waterproof heating of claim 2, wherein: The top plate and the bottom plate are provided with an integrally bent handrail in the middle. The top plate and the bottom plate are provided with a positioning part on the wall away from the bent frame. The positioning part is used to install the protective frame.
6. The lithium battery system with waterproof heating of claim 1, wherein: The heating film is an epoxy resin heating film.
7. The lithium battery system with waterproof heating of claim 1, wherein: The heating film is a resistance heater.
8. The lithium battery system with waterproof heating of claim 1, wherein: The outer periphery of the door is equipped with a waterproof sealing ring.
9. The lithium battery system with waterproof heating of claim 1, wherein: The box body has a predetermined thickness or is a hollow plate structure.
10. The lithium battery system with waterproof heating of claim 6, wherein: The heating film is integrally injection molded onto the positioning frame using epoxy resin.
