High-power module for rail transit

Abstract

The invention belongs to the technical field of lithium ion battery temperature control and grouping, and relates to a high-power module for rail transit, which is characterized in that a leading-out end is arranged above the left side of a battery cell unit; insulating partition plates are mounted on left and right sides of the cell units; clamping plates are mounted on left and right sides of the insulating partition; protective covers are mounted on the front and rear sides of the cell units; a busbar is arranged below the front side of the front side protective cover; the battery cell units are connected in parallel through the busbars to form parallel units and then form series units through the busbars; the leading-out end comprises a leading-out fixing seat which is arranged above the left side of the battery cell unit; the front end and the rear end of the left side of the lead-out fixing seat are respectively provided with a lead-out copper bar and a quick plug; the fuse is mounted in the middle of the left side of the lead-out fixing seat The leading-out copper bar is connected with the series unit; one end of the fuse is electrically connected with the leading-out copper bar, and the other end of the fuse is connected with the quick plug. The module has the multifunctional characteristics of air cooling and water cooling; and the device has voltage-resistant design, optional accessories and reliability.

Description

technical field [0001] The invention belongs to the technical field of temperature control and grouping of lithium-ion batteries, and relates to a temperature-controlled battery module for rail traffic, in particular to a high-power module for rail traffic. Background technique [0002] Batteries (including: hot battery cells, battery packs and lithium-ion batteries, etc.) may be in different working environments during use, and thus exhibit different performances. For example, under extreme conditions such as high temperature, low temperature, high voltage, and high-rate charging and discharging, overheating of the battery may occur, which may damage the reversibility of the battery, and even directly shorten the life of the battery, affecting the operating cost of the battery. Therefore, the temperature control of the battery is a problem that must be faced in the normal use of the battery. The current prior art about batteries has the following disadvantages: [0003] 1...
