Separated battery pack system

Abstract

The invention discloses a separated battery pack system, and the system comprises a battery bin and an energy management box assembled outside one side of the battery bin; a high-voltage wire outlet is formed in the position, matched with the high-voltage device integration cavity, of the battery bin, and a line of the high-voltage device penetrates through the high-voltage wire outlet, extends into the battery bin and is electrically connected with the battery module. According to the battery pack system, the energy management box is integrated on the side face of the battery bin, the high-voltage device is integrated in the energy management box, the high-voltage wire outlet is formed in the battery bin so that the high-voltage device can be electrically connected with the internal battery module, and the structure of the upper cover of the battery system is improved according to the position and the section size of the energy management box; the energy management box is sealed by the energy management box cover plate of the upper cover of the battery system, and the energy management device is integrated outside the battery compartment in the integration mode, so the damage to the structure of the battery compartment is avoided, the internal battery module is protected, the safety is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of battery packs for new energy vehicles, in particular to a separate battery pack system suitable for new energy vehicles. Background technique [0002] At present, with the development of the economy, the problems of environmental pollution and energy shortage are becoming more and more serious. Driven by environmental protection, energy saving and the development of green and renewable energy, electric vehicles are widely used as a new type of new energy vehicles. Research. [0003] Lithium-ion power battery system, as the core component of electric vehicle power, is the top priority. It is widely used in electric vehicles because of its advantages of small size, light weight, high energy density, good cycle life, green environmental protection, and high safety performance. , and the energy management of the battery system is the guarantee for the stable performance of the battery system. In recent years...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, most of the energy management devices are placed inside the battery pack, which occupies a large space. Since the high-voltage lines connected to the energy management device are all arranged inside the battery box, the failure risk of the battery pack is increased. In addition, the energy management device carried in the battery box will inevitably destroy the structure of the box, which will reduce the strength of the battery box

[0005] In addition, the built-in method of the energy management device has a large potential safety hazard. Due to the aging of the circuit components in the device, the entire battery pack will fail, so the cost of replacement and maintenance will also greatly increase.
