Features Of The Lithium Battery PACK
There is a complete range of functions that can be applied directly.
Variety of types. The same application requirements have a variety of PACKs that can be realized.
The battery pack PACK requires a high degree of battery consistency (capacity, internal resistance, voltage, discharge curve, and life).
The cycle life of a battery pack PACK is lower than that of a single cell.
Use under defined conditions (including charging and discharging currents, charging methods, temperature and humidity conditions, vibration conditions, degree of stress, etc.)
Li-ion battery pack PACK protection boards require a charge equalization function.
High voltage, high current battery pack PACKs (e.g. EV batteries, energy storage systems) require a battery management system (BMS), CAN, RS485, and other communication buses.
The battery pack PACK has higher requirements for the charger, some of which require communication with the BMS. The aim is to make each battery work properly, fully utilize the energy stored in the battery, and ensure safe and reliable use.
The Design Of Lithium Battery PACK
Fully understand the use requirements, such as application environment (temperature, humidity, vibration, salt spray, etc.), use time, charging, discharging methods and electrical parameters, output methods, life requirements, etc.
Select qualified batteries and protection circuit boards according to the requirements of use.
Satisfy the requirements of size and weight.
Reliable packaging to meet the requirements.
The simplicity of the production process.
Optimal solution.
Cost minimization.
Detection is easy to achieve.
Precautions For The Use Of Lithium Batteries
- Do not put it into a fire or use it close to heat sources!
- Do not use metal to connect the positive and negative output terminals directly together.
- Do not use beyond the temperature range of the battery.
- Do not squeeze the battery with force.
- Use a special charger or charge in the correct way.
- Recharge the battery every three months when it is in storage. Store at storage temperature.
