6 FAQs about [Welding of the protection board of the rechargeable lithium battery pack]
What is a lithium battery protection board?
The lithium battery protection board is a core component of the intelligent management system for lithium-ion batteries. Its main functions include overcharge protection, over-discharge protection, over-temperature protection, over-current protection, etc., to ensure the safe use of the battery and extend its service life.
How does resistance welding affect a battery cell?
4.1.2 Effect on the battery cell Small-scale resistance welding is often the preferred method for joining Li–ion batteries into battery packs. This process ensures strong joints with an almost complete elimination of the heat impact on the joined workpieces during a short time.
Are welds good for battery packs?
Having made repeated across-the-board improvements to boost battery pack performance, the company has shifted its focus in recent years to improving the quality of welds in batteries. Welds are used in a variety of joining steps throughout the battery cell and battery pack manufacturing process.
What are the technical parameters of lithium battery protection boards?
Prevent the battery from being damaged by excessive current. Important technical parameters of lithium battery protection boards include overcharge protection, over-discharge protection, over-current protection, short-circuit protection, temperature protection, internal resistance, power consumption, etc.
Why do battery cells need to be welded?
Battery cells are most often put into modules or packs when produced for electrically driven vehicles. The variable of greatest influence when welding battery packs is the contact resistance between the cell and the connection tab. It is crucial to minimize this variable as much as possible to prevent energy loss in the form of heat generation.
Is UWB suitable for welding a cylindrical battery cell?
UWB is also suitable for creating electrical connections between cylindrical battery cells. Although proper fixation of the cell is paramount for the welding, as any significant lateral movement will reduce the vibration amplitude and consequently diminish the power of the welding process.
