Lithium Ion Battery Pack Design Pouch Cell Battery Pack Assembly Tech Consult

1. Description :

We provide lithium ion Pouch Cell Battery Pack Assembly Tech Consult and advisory when you want to do a lithium ion battery pack design

Requirements for electric core:

Select corresponding electric core according to the design requirements.The parallel and series batteries shall have the same type and model, and the difference in capacity, internal resistance and voltage value shall not be greater than 2%.In general, the capacity loss of the battery is 2% - 5% when it is combined in series and parallel.

The more the number of batteries, the more the capacity loss.No matter it is a pouch cell battery or a cylindrical battery, it needs to be combined in multiple strings. If the consistency is poor, the battery capacity will be affected.The battery with the lowest capacity in a group determines the capacity of the whole group of batteries.High current discharge performance is required.The starting current of the motor is three times of the normal working current, and the power performance of the motor can be improved only when the large current is discharged.

Good heat dissipation of battery is required.The number of batteries is large, and the temperature rise of the batteries inside the battery box is not easy to disperse, resulting in uneven temperature and different discharge characteristics among the batteries, resulting in long-term degradation of battery performance. High level of production technology.

The battery shall be able to withstand the vibration impact of a bumpy road.It has a high demand for production technology, especially spot welding technology.Test shall be conducted after welding to prevent faulty welding and desoldering.
