This thermally conductive silicone adhesive has good bonding effect and rapid curing ability to adapt to large-scale mechanized production operations, and has good thermal conductivity and shock filtration after curing. Many square cells are stacked, and the fit assembly between the square cells, the position between the battery, the module separator or the module side plate, can be adhered and fixed using thermal conductive silicone adhesive, and can be attached to the pouch battery resemblance.

The power battery pack of new energy works for a long time in a harsh environment, and its battery life is also shortened. Uneven temperature distribution in the battery box can lead to unbalanced performance of each battery pack. The thermal monitoring and thermal management of the new energy battery pack is directly related to the performance of the entire vehicle, and it is crucial to the overall operation of the vehicle!

The battery pack temperature control system is a set of systems. BQ27505YZGT-J4 ensures that the battery pack works within a suitable temperature range. Changes in the internal temperature of the battery will lead to changes in battery performance. For example, at low temperatures, the available capacity of the battery will drop significantly. If the temperature is too low, instantaneous voltage overcharge will also occur, resulting in the precipitation of electrolyte in the battery; thus causing a short circuit.

The heat pipe system needs to be preheated when the battery temperature is low to ensure low-temperature charge and discharge efficiency and safety. After the battery works for a long time, the battery temperature rises, and thermal management is needed to effectively dissipate heat and heat to avoid local battery packs. Overheating affects life and safety.

Various lithium battery structures require different thermal interface material solutions:

1. Soft pack battery:

It is formed by stacking several pouch batteries. The pouch cells are generally isolated one by one with an aluminum plate, and thermally conductive silica gel is used to bond and fix the pouch battery and the aluminum plate. This thermally conductive silicone adhesive has good bonding effect and rapid curing ability to adapt to large-scale mechanized production operations, and has good thermal conductivity and shock filtration after curing.

2. Square battery:

Many square cells are stacked, and the fit assembly between the square cells, the position between the battery, the module separator or the module side plate, can be adhered and fixed using thermal conductive silicone adhesive, and can be attached to the pouch battery resemblance. During the filling process, thermally conductive silica gel and two-component thermally conductive adhesive are used for filling, so that the heat energy of the battery pack can be effectively transmitted to the outside world, and at the same time, the vibration and impact can be slowed down to protect the normal operation of the battery.

3. Cylindrical battery:

Various cylindrical batteries, such as ordinary 18650 batteries, are installed and fixed in the bracket to form a battery module, so that the thermal conductive silicone adhesive is used between the battery module and the external fireproof board, which has thermal conductivity and flame retardancy. In order to further improve the heat exchange effect and protect the battery pack, it is necessary to pour a low specific gravity, flame retardant and flexible thermally conductive potting compound into the battery module.
