At present, from the development of market situation, the battery package electric core utmost point post described in the prior art need weld respectively on electric core utmost point post in the top of battery package, and the busbar occupies the top installation space of battery package, and the welding has the rosin joint, probably leads to the risk of desoldering because of electric core inflation in electric core uses.
In the development of electric automobiles, a power battery pack is used as a core component, and the safety of the power battery pack directly influences the safety performance of the whole automobile. Therefore, higher demands are made on the design of the battery in terms of strength, rigidity, waterproof sealing property, insulation property, electromagnetic interference resistance and the like, and particularly, the requirement on the waterproof sealing property is that the risk of short circuit due to water inflow must be prevented because the internal voltage of the battery pack is high. The sealing schemes widely used at present comprise sheet metal boxes, die-cast aluminum boxes and the like. And the rubber strip with the strip-shaped cross section is mainly adopted and is stuck between the flanging of the box body and the plane of the cover plate, and sealing is realized through up-down or left-right extrusion. For the die-casting aluminum box body, the light weight design of the product is difficult to realize due to the limitation of the minimum wall thickness; if the die-casting process of integral forming is adopted for the battery box with larger size, the investment cost of the die-casting process is very high; in addition, the battery pack box body structure integrally cast in the size has high box body rigidity, so that the requirement on the strength of the box body is high, the uniformity and the magazine air holes must be strictly controlled, professional inspection equipment needs to be matched, and the production difficulty and the processing cost are further increased.
For a sheet metal box body, the edges of the box body need to be fully welded, the structural strength and the sealing performance can be greatly improved by the currently adopted tower edge splicing welding method, but due to the reasons of a plurality of welding seams, a thin steel plate and the like, the processing difficulty is high, and the product consistency is not high; secondly, in the conventional design of the sealing structure of the box body, the cover plate and the cover plate, due to the limitation of bending precision, the designed fit clearance is difficult to control, and the sealing property is difficult to achieve the expected effect; to the integral type battery box that needs to participate in the frame deformation, the buckling deformation of frame can make and produce relative displacement between battery box and the apron, and sealed effect will receive very big image, and long-term effect has the risk of seepage even.
In the aspect of resource utilization, the power lithium battery also has the problems of incomplete recovery system and weak recovery value. Although large-scale recycling enterprises such as Geringmei and Hunan Bangpu are also developed in China, the recycling of the power lithium battery has the problems of high recycling cost and incomplete recycling industrial chain. The recycling of the power lithium battery needs to fully use the experience of recycling the lead-acid battery. The lead-acid battery establishes a complete recovery network and a recovery industrial chain, and generally has 30% recovery value during recovery.
Recycling the power lithium battery: a new path for battery cost reduction. The recycling of the power lithium battery is a link between a new energy automobile and the recycling of the power lithium battery, and the power battery is disassembled, detected and classified for secondary use after the automobile is used, so that the cascade of the power battery is realized, and the aim of reducing the cost of the power battery by 30-60% is fulfilled. Generally, the scrapping standard of new energy automobiles for power lithium batteries is that the battery capacity is lower than 80%, if the residual capacity is still 70-80%, direct resource recovery of the batteries is extremely waste, and the recycling of the power lithium batteries is particularly important for reducing the battery cost.
The field of recycling of power lithium batteries of new energy automobiles mainly aims at the fields of ICT (information and communications technology), families, renewable energy power generation and energy storage and the like. Although the recycling practice of the power lithium battery is not developed in China, the power lithium battery has been demonstrated in Japan and the United states for many years. The research on recycling of power batteries starts from the beginning of the development of new energy automobiles, and the early research works provide good reference for the development of the research on recycling of batteries in China.
With the progress of science and technology, the demand for electric power energy is increasing day by day. For the demand of electric power, an alternating current or a battery pack formed by connecting a plurality of battery cells in series can be used as the power supply. The advantage of using a battery pack as a power source is that the power source is portable and not limited to use in a fixed location. A conventional battery pack mainly includes a plurality of battery core groups for providing power and a battery pack monitoring unit electrically connected to the battery core groups for detecting states of the battery core groups, such as voltage, current, temperature, and the like. Under the current situation, in the control of most handheld dust collector battery pack products, a discrete operational amplifier is used for collecting current, voltages at two ends of a sampling resistor are zoomed through the operational amplifier, and then an AD voltage value is collected through an MCU and converted into corresponding current.
Cell (Cell): the electrochemical cell is a minimum functional unit of a single electrochemical cell containing a positive electrode and a negative electrode, is generally not directly used, is different from a cell containing a protection circuit and a shell, can be directly used, and has high energy density to store electric energy as much as possible, so that an electric automobile has longer endurance mileage. In addition, the service life of the battery cell is also the most critical factor, and the damage of any one battery cell can cause the damage of the whole battery pack.
Battery Module (Module): when a plurality of electric cores are packaged together by the same shell frame, and contact is carried out with the outside through unified boundary, a module is formed.
Battery Pack (Pack): when several modules are controlled or managed together by the BMS and the thermal management system, the unified whole is called a battery pack. The difference of the battery core, the module and the battery pack is that whether an additional management system exists or not is different besides the number of the batteries.
Battery Management System (BMS): the battery management system is commonly called as a battery caregiver or a battery manager, and is mainly used for intelligently managing and maintaining each battery unit, preventing overcharge and overdischarge of the battery, prolonging the service life of the battery and monitoring the state of the battery. The battery management system unit comprises a BMS battery management system, a control module, a display module, a wireless communication module, electrical equipment, a battery pack for supplying power to the electrical equipment and a collection module for collecting battery information of the battery pack. Initial life (BOL): the service condition of the power battery just delivered. End of life (EOL): and when the energy of the power battery system is reduced to 80% of the initial energy, or the real-time power peak is reduced to 85% of the initial power peak, the service life is considered to be ended.
State of charge (SOC): percentage of remaining capacity after battery discharge to full charge capacity. High low voltage interlock (HVIL): when the low-voltage power is cut off, the high-voltage loop can be cut off simultaneously through the control of a low-voltage signal.
