The essential components of a battery PACK consist of a single battery module, electrical system, thermal management system, box, and BMS.
Battery Module: This serves as the "heart" responsible for storing and releasing electrical energy.
Electrical System: Comprising copper liners, high-voltage wire harnesses, low-voltage wire harnesses, and electrical assurance devices, it acts as the circulatory and neural network of the battery PACK.
Thermal Management System: Utilizing methods such as air cooling and liquid cooling, this system ensures the battery operates at an optimal temperature, enhancing its cycle life.
Box: Comprising a box, box cover, metal bracket, panel, and fixing screws, it functions as the "bone" providing support, mechanical resistance, and environmental protection.
BMS (Battery Management System): Serving as the "brain," BMS is responsible for measuring parameters such as voltage, current, and temperature, as well as performing functions like equalization.
Applications of Lithium Batteries Pack
Electric Vehicles - Provide propulsion power to fully electric and hybrid vehicles. Require very high capacity (5o-1ookWh), power density, safety and cycle life. Complex liquid cooled designs.
Consumer Electronics -Mobile phones, laptops, power tools and other portable devices. Focus on cost, compact size and lightweight. Air cooled pouch or prismatic cells in plastic enclosures. 1-1ooWh capacity range.
Aerospace - Used in aircraft for emergency power and to start engines. Durable designs withstand vibration. Safety and reliability are critical.
Stationary Storage - Grid energy storage, backup power, off-grid solar/wind systems. Focus on low cost, long cycle life. Air/liquid cooled in racks or containers.
Medical Devices - Implantable and wearable medical devices. Very compact, safe and durable batteries are required. Ultrathin flexible cells down to 1oo microns thick.
Precautions for Using Lithium Batteries Pack
- The wires connected to the lithium-ion battery pack must be firm, and the copper wires must be prevented from intersecting with each other. If they intersect, the controller of the lithium-ion battery will be damaged.
- When wiring, be sure to pay attention to the waiting time for the lights. This time is set by the controller. Lithium-ion battery packs are generally half-charged when they leave the factory, so the electronic equipment we buy is generally Half-electric, these are normal phenomena.
- It is not suitable to assemble the lithium-ion battery pack at night, so try to assemble it during the day.
- Storage requirements: In an environment with a temperature of 25±5℃ and a humidity of not more than 50%, the corrosion of the aluminum foil by air and water vapor must be prevented during transportation.
- The internal storage of electrical energy in lithium-ion batteries is achieved by a reversible chemical change in electrochemistry. Excessive discharge will cause irreversible reactions to such chemical changes. Therefore, lithium-ion batteries are most afraid of overdischarge.
- Attention should be paid to the use and positioning of the cells of the lithium-ion battery pack to prevent collisions and open circuits. The cells must be firm to prevent loosening.
Storage Environment of Lithium Batteries Pack
- Optimal storage temperature: 15°C~25°C.
- Extreme temperature: 0°C～60°C.
- Optimal storage humidity: 45%~75%.
- Extreme humidity: 5% RH～95% RH (no condensation).
It is worth noting that an independent temperature control system is also required to avoid temperature fluctuations. Direct sunlight or high-humidity environments (such as areas at risk of condensation) are strictly prohibited. The battery packs must be stored vertically, and inverted or lateral placement is forbidden to ensure uniform force on internal cells.
