Due to the diversity battery application field, lithium battery pack customization is a mainstream trend recently. Through customization, the lithium battery pack can be most suitable according to your space and usage technical requirements. Here SmartPropel listed 7 points that we should concern during customization.
1.Forbidden different types battery cell mixed-use
Different types of battery cell can not be mixed-use, battery structure, chemical composition, and battery performance deviation will lead to a serious potential safety hazard.
2.Forbidden different batch battery cell mixed-use
Different batches of lithium cells should not be mixed-use, which will affect the consistency between the individual battery cell. The products of the same batch are those from the same mixing process, with the same chemical composition and with the closest consistency between the cell monomers.
3.Choose “Top A” “EV battery level” cell
There are different levels of battery cells, from “A level”, “B level” to “Recycled” battery spread in the market. Even for “A top” battery cells, there’s also have different classify, separately for customer products, for ESS, and for EV. “EV battery level” cell is the best lithium battery cell, for excellent electric vehicles have high requirements on the consistency, cycle life, and discharge rate. The battery cell is the soul of the battery pack. Only with excellent cells can ensure the battery pack wonderful performance.
4.Select high precise BMS
In order to make sure electric vehicles work well during the operating, the traditional protective board is not enough, except protects the battery no fire, no explosion, prevent over-discharge, over-charge, and short circuits, BMS has further functions, such as heating management, capacity calculation, power detection, SOC&SOH detection, Communication function, system self-check, etc. High precise BMS will protect the battery well during usage and ensure the battery have a longer cycle life and better performance.
5.Apply high-quality accessories
An excellent battery pack can not exist without high-quality accessories. Adopt high-temperature-resistant wire output mode to increase conductor reliability. Use strong battery bracket and sheet metal shell enhance the battery pack robustness, IP65 waterproof, easy to carry and assemble.
6.Adopt first-class technology and advanced skills
Make sure the battery cells must be strictly tested and capacity grading before assemble. Introduce high precision electric welding machines, all workers are strictly trained with advanced technology skills for the packing procedure and notes.
7.Comply with international standards
The battery pack should comply with international standards. Ensure the battery pack is assembled with stable performance and long cycle life. All battery packs will be tested at least 48 hours before delivery.
