Novel battery module

Abstract

The invention belongs to the field of batteries, and particularly relates to a novel battery module. The novel battery module comprises a battery pack and a battery box, wherein the battery pack consists of batteries; the battery box is arranged outside the battery pack; the top ends of the batteries are provided with anode lugs and cathode lugs; and the battery box consists of four lateral plates and one base plate. The novel battery module is characterized in that: the base plate of the battery box is provided with a base; grooves are formed in the base; a battery is inserted in each groove; a gap is reserved between each two batteries; one lateral plate vertical to the plane of the gap is provided with a fan; another lateral plate parallel with the lateral plate provided with the fan is provided with a vent hole; the anode lug of each battery is fixed on an anode which is arranged on a connecting piece to form the battery module; the cathode lug of each battery is fixed on a cathode which is arranged on the other connecting piece to form the battery module; and the two connecting pieces are provided with a wiring terminal respectively. The battery module not only has a simple structure but also has high heat dispersion, not only can improve the consistency between each two batteries but also can prolong the service life of the entire battery module, and has an extensive market prospect.

Description

Technical field [0001] The invention belongs to the field of batteries, and particularly relates to a new type of battery module suitable for electric vehicles and energy storage systems. Background technique [0002] As primary energy resources such as oil and natural gas become more and more scarce, mankind is facing severe challenges that the living environment may continue to deteriorate. In order to reduce energy costs and achieve sustainable development in the world, countries all over the world have carried out research on electric vehicles and energy storage technology. The idea is to use large-capacity batteries as power systems and energy storage systems. Therefore, choosing the right battery has become one of the keys to the development of electric vehicle technology and energy storage technology. [0003] Currently, the batteries used in electric vehicles and energy storage systems are mainly high-capacity lithium-ion batteries. Lithium-ion batteries have the advantag...

AI Technical Summary

Problems solved by technology

Lithium-ion batteries generate heat during the charging and discharging process. When the batteries are connected in series and parallel, due to the small gap between the batteries and the insufficient ventilation of the box, there will be a large temperature difference between the cells.

Lithium-ion batteries are greatly affected by temperature. When the battery temperature is different, it will cause inconsistencies in the whole box of batteries, which will affect the service life of the whole battery pack and leave a safety hazard.

In the existing battery modules, all the batteries are usually placed side by side in the battery box and clamped and fixed by the battery separator. The battery module with this structure has poor heat dissipation effect, and it is difficult to ensure the consistency of the service conditions of all batteries.
