Description

TECHNICAL FIELD

[0001] The utility model relates to battery shell technical field, concretely is a battery shell assembly. BACKGROUND

[0002] Battery refers to the cup, the space of other container or composite container of having electrolyte solution and metal electrode to produce electric current with part, can convert chemical energy into electric energy device. Have the division of positive pole, negative pole. With the progress of science and technology, battery refers to the small device that can generate electric energy. Such as solar cell. The performance parameters of battery mainly have electromotive force, capacity, specific energy and resistance. Using battery as energy source, can get the electric current with little influence from outside, and the battery structure is simple, carries convenient, charges and discharges operation simple and easy to operate, is not affected by outside climate and temperature, and the performance is stable and reliable, plays a very big role in various aspects of modern social life, in chemical battery, chemical energy directly converts into electric energy is the result of spontaneous oxidation, reduction and other chemical reactions in the battery, which are carried out on two electrodes. Negative active material is composed of a reduction agent with a negative potential and stable in electrolyte, such as zinc, cadmium, lead and other active metals and hydrogen or hydrocarbon compounds. Positive active material is composed of an oxidizing agent with a positive potential and stable in electrolyte, such as manganese dioxide, lead dioxide, nickel oxide and other metal oxides, oxygen or air, halogen and its salt, oxygen-containing acid and its salt, etc. The electrolyte is a material with good ion conductivity, such as acid, base, salt solution, organic or inorganic non-aqueous solution, molten salt or solid electrolyte, etc. When the external circuit is disconnected, although there is a potential difference (open circuit voltage) between the two electrodes, there is no current, and the chemical energy stored in the battery is not converted into electric energy. When the external circuit is closed, there is a current flowing through the external circuit under the action of the potential difference between the two electrodes. At the same time, in the battery, since there are no free electrons in the electrolyte, the transfer of electric charge must be accompanied by oxidation or reduction reaction at the interface between the electrolyte and the active material of the two electrodes, and the transfer of reaction substances and reaction products. The transfer of electric charge in the electrolyte is also completed by the migration of ions. Therefore, the normal charge transfer and mass transfer process in the battery is the necessary condition to ensure normal output of electric energy. During charging, the direction of the electric transfer and mass transfer process in the battery is opposite to that during discharging; the electrode reaction must be reversible to ensure the normal process of mass transfer and electric transfer in the opposite direction.

[0003] The battery is composed of an electric core and a shell. The battery shell is mainly used to bear the power battery system components such as battery packs, electrical modules and cooling modules, and at the same time, protects the battery and electrical system from being damaged when the vehicle is subjected to external collision, impact and extrusion. The materials of the battery shell currently mainly include traditional metal materials such as steel plates, aluminum plates, extruded aluminum profiles and die-cast aluminum, as well as various lightweight composite materials such as glass fiber reinforced composite materials, SMC composite materials and carbon fiber composite materials. The innovation of shell materials, cost reduction and lightweight are of great significance to the safe development of new energy vehicles and electrochemical energy storage.

[0004] Storage life refers to the longest time allowed for storage between the time the battery is made and the time it is first used, measured in years. The total period including the storage period and the use period is called the effective period of the battery. The life of the stored battery is divided into dry storage life and wet storage life. Cycle life is the maximum number of charge and discharge cycles that a storage battery can achieve under specified conditions. When the specified cycle life is specified, the system of charge and discharge cycle test must also be specified, including charge and discharge rate, discharge depth and environmental temperature range.

[0005] In order to improve the service life of the battery during use, a protective shell assembly body is arranged on the surface of the battery, which protects the battery inside through the protective shell assembly body, prevents external factors from affecting the normal use of the battery, although the use of the protective shell assembly body can effectively protect the battery, but when the battery itself appears, it is inconvenient to take out and replace because it is located inside the protective shell assembly body, therefore we provide a battery shell assembly.
