Description
Technical Field
The utility model belongs to the technical field of the new energy automobile group battery is thermal-insulated fire-retardant, concretely relates to heat insulating sheet for new energy automobile group battery.
Background
The new energy automobile industry in China begins at the beginning of the 21 st century. In 2001, a new energy automobile research project was listed as a major scientific and technological subject of '863' in the period of 'fifteen' in the country, and a strategy for advancing to a hydrogen-powered vehicle target from a gasoline vehicle as a starting point was planned. Since the 'eleven-five', the strategy of 'energy conservation and new energy vehicles' is put forward in China, and governments are highly concerned about the research, development and industrialization of new energy vehicles, so that a complete research, development and demonstration layout of new energy vehicles is formed. The new energy automobile refers to all other energy automobiles except gasoline and diesel engines. Including fuel cell vehicles, hybrid vehicles, hydrogen-powered vehicles, solar vehicles, and the like, have a relatively low exhaust emission.
As the new energy automobile meets the environmental protection requirement vigorously advocated by the nation, the sales volume of the new energy automobile is increased year by year, the application range is enlarged, and most new energy automobiles sold in the current Chinese market are hybrid electric vehicles and pure electric vehicles. The power supply mainly comprises a lithium ion battery, a nickel-hydrogen battery, a fuel cell, a lead-acid battery and a super capacitor. Because the power that the automobile traveles needs is very big, the new energy automobile that adopts electric power to provide power need the battery compartment for a long time to provide great electric current in order to guarantee can normally travel, guarantees the provision of power. After the vehicle-mounted battery outputs electric energy for a long time, the battery body can obviously generate heat by long-time chemical reaction in the battery, and the risks of combustion and explosion exist. The traditional core module adopts plastic partition plates to separate batteries from each other, and has no practical use, so that the traditional core module has heavy weight and cannot play a role in protection, and the problems of dissolution, ignition and the like of the partition plates caused by overhigh battery temperature are easily caused. The protective felt adopted in the prior art is simple in structure and easy to deform, so that the protective felt cannot be in overall contact with a battery pack well, and cannot achieve a good heat insulation effect when a battery generates heat seriously. Therefore, how to realize the heat insulation and flame retardance in the field of new energy automobiles is the first consideration for realizing long-term development of new energy.
