Lithium-ion battery manufacturer details the method of lightning of electric vehicle lithium-ion battery system. About electric vehicles, the battery pack is the core storage unit of the automobile. It can effectively add the battery energy density to increase the battery life.

The problem of short-term shortage of electric vehicles is an important factor that restricts the development of electric vehicles. By lithium ions Battery manufacturers talk about the light quantification of lithium-ion battery systems for electric vehicles. Methods to realize the lightweight of the lithium ion battery system of electric vehicles, the car is lightly quantified means that the car is not reduced by the original driving safety, campaign, shock resistance, and comfort, and the car itself is not improved.

, Have a goal to reduce the weight of the car itself. Car light weight is the advantage of design, material and advanced processing technology. Important way to realize the lithium-ion battery system of electric vehicles 1.

Improve the energy density of the monomer cells in electric vehicles important in electric vehicles important, lithium iron phosphate and ternary materials as positive material, lithium iron phosphate ion battery due to safety The best performance and cycle life have been largely industrialized. Many of the domestic death, the wrong manufacturer chooses the production of this type of battery, but the lithium phosphate ion battery monomer is lower than energy, and the ternary battery is higher than energy. Can cater to the market's requirements to increase the production of three yuan lithium ion battery, so the new material system or battery system should further meet the above objectives.

2, reduce battery system accessories quality to reduce battery system accessories quality management can also improve battery system energy density. Battery system is an important part of the battery case. It is the "heart" of electric cars.

For the safety of the safety of the battery, high-strength, low-density performance materials can be selected in the process of reducing the quality of the battery. Its basic materialization performance also reduces its quality, so that practical applications can be used. 3.

Optimize the battery system design by means of a reasonable structural design of battery system, reduce material use, and combine computer-aided engineering simulation analysis, to achieve lightweight purposes without changing. Manufacturing processes and materials, structures are complementary, to find the adaptable advanced process to achieve light weight. Performing a lightweight engineering specific measures 1) Optimized design of the components Important include the optimal bearer path, homogeneous structure and optimized geometric shape; 2) Important in manufacturing process is an important laser spectral soldering sheet, deep pull extension And hydraulic forming, lightweight castings, spot welding and laser tie welding and other connection techniques; 3) High-strength steel and advanced high-strength steel, aluminum alloy and magnesium alloy, composite application technology, fiber reinforcement The application of composite materials, etc.

, ultimately achieve the shortest development time, lowest cost and white car world price. In order to address environmental pollution, energy shortages, etc., developing pure electric vehicles is an inevitable choice for realizing my country's environmental protection, energy security, and sustainable development path.

The pure electric vehicle battery is low, and the short board in which life is poor, therefore is of great significance to the lightweight research of electric vehicles. Lightweight is not only to reduce the quality of parts, but to ensure optimization under the premise of performance. In summary, electric vehicles must be made from lightweight, lightweight to perform lightweight development and system integration from all subsystems such as body, chassis, engine.

The use of new composite materials and new batteries are key directions. Just adhere to the development of a series of innovative activities, namely new technologies, new platforms, new materials, new processes and new batteries can develop electric vehicles with real commodity.
