Application of organic silicon irrigation seal in the new energy vehicle power battery pack
Organic silicon materials have stable dielectric insulation, which is an effective barrier to prevent environmental pollution. At the same time, the stress caused by the impact and vibration can be eliminated within a large temperature and humidity range. In addition to maintaining their physical and electrical properties in various working environments, they can also resist ozone and ultraviolet degradation, and have good chemical stability. So today I will talk to you about the organic silicon irrigation and sealing in new energy electric vehicles
Power Battery Group (
The rapid development of new energy electric vehicles has also led to the rapid development of power batteries. The energy density of power batteries has continued to increase, and the battery life has also been significantly improved. However, under the rapid development, the hidden dangers also followed. The key to the technology of new energy electric vehicles is the charge and discharge technology and safety performance of high -energy density batteries. During the use of power batteries, it is necessary to maintain an excellent waterproof and dustproof effect, and easy to heat and spontaneous combustion is a first -class problem that affects the safety of power batteries.
The characteristics of organic silicon irrigation seal
Heshun organic silicon irrigation and sealing can be electrical under high humidity, extreme temperature, thermal circulation stress, mechanical impact and vibration, mold, dirt and other harsh strips.
Electronic devices and components are protected. Organic silicon sealing can reduce stress caused by vibration, mechanical impact and thermal cycle. Organic silicon gels can encapsulate the most vulnerable crystal lines and have powerful pollution prevention and stress protection effects. All these qualities can improve complex electronic components, and even the performance, reliability and period of use of components with slender wires and joints, and are easy to process and repair.
The safety protection of organic silicon sealing glue for power batteries
The safety protection of the power battery of the organic silicon irrigation seal is mainly manifested in: the temperature, anti -impact performance, the short circuit of the power battery module of the power battery module, the internal short circuit of the power battery module, and the protection of the power battery module.
1. Protection of the temperature of the power battery module
In the use of new energy electric vehicles, the thermal management of the power battery pack mainly uses the battery management system (
) Regulate, protect and control. The deviation of the internal temperature of the battery system during the working of a lithium -power battery will affect the stability and endurance of the power battery unit, and will also affect the service life of the battery pack to a certain extent. Therefore, the organic silicon -sealing glue with good thermal conductivity can help the power battery packages of the power battery pack, which helps the heat buffer of the battery unit, play a good thermal balance, and ensure the safety and stability of the battery module.
2. Protection of the impact performance of power battery modules
When cars are driving on the road, there are often scratches and collision accidents, and the power battery packs of new energy electric vehicles are particularly fragile. The power battery packs that are not specially protected are easily collided with external forces to squeeze and fail, and even a fire explosion occurs. Organic silicon -sealing has a certain hardness and good elasticity. It can play a certain elastic buffer effect on the power battery pack when impact, so as to protect the battery pack. sex.
3. Protection of short circuit inside the power battery module
The safety of power batteries is a key factor in restricting its use of new energy electric vehicles. The internal short circuit of the battery is an important reason for affecting the safety of power batteries.
Hishun organic silicon irrigation and sealing has good electrical insulation, so the battery module encapsulated by organic silicon -sealing glue can appear in the battery in the short circuit of a single battery or pierced the battery cell. The chain response plays a blocking role, protects the security of adjacent battles, prevents the chain reaction, can better protect the power battery module and improve the safety of the battery module.
4. Protection of overcoming power battery modules
The power battery pack of new energy electric vehicles consists of a hundred thousand battery string in parallel. Although the self -explosion rate of the battery cell is one -million, the cells will still explode. Due to organic silicon irrigation and sealing energy
Eliminate the stress caused by impact and vibration
, And have good flame retardability, so when a single battery is overcharged, it can cut off the chain reaction and protect the surrounding batteries from being affected. The flame -retardant explosion -proof capacity of the silicon seal directly affects the safety after the battery module is over -controlled, which can ensure that a battery cell in the battery module is overcharged and exploded, which will not cause the combustion of the peripheral battery cells. The silicon -produced silicon -producing silicon is still an insulating substance after burning.
The safety of power lithium batteries is critical to the development of the new energy vehicle industry. This will challenge battery manufacturers and promote them to design smaller, lighter and cheaper large -capacity lithium battery pack products. These higher energy density battery packs can provide more sufficient and lasting energy. The characteristics of organic silicon materials make it stand out in various electronic equipment and automotive applications, and helps you cope with the design and production of the design and production of other electric vehicle components in the future, and escort new energy vehicles to protect the new energy vehicles.
