What are the key points for the Ebike 18650 lithium battery assembly process?

Ebike Battery

18650 lithium battery is one of the most common Ebike lithium-ion batteries on the market, so what are the key points of the lithium-ion battery pack process? Let’s take a look.

The 18650 lithium battery pack process is mainly based on the structure of the battery, most of the 18650 lithium battery pack process features are similar, its characteristics are battery cell series and parallel. 18650 cell pack process features are distinct, one of the biggest features is the flexible combination, most of the continuous orders can be achieved semi-automatic to complete, it is conceivable that 18650 lithium battery pack process is now more and more streamlined, 18650 lithium cell, BMS, highland barley paper, electricity indicator, plastic bracket and other supporting materials together to form the pack and most of the 18650 battery pack types are suitable for this process.

Process quality characteristics of 18650 lithium battery pack

  1. Adopt high-quality lithium batteries, need qualified and stable suppliers to provide good performance single cell, single cells are qualified to use after a series of safety tests and performance tests.
  2. Require low internal resistance and good consistency, low internal resistance to ensure high current discharge capacity, platform, heat dissipation, etc.
  3. The battery structure adopts a ventilation design, the space between two adjacent batteries is not less than 2mm, this structure requires fixing the battery with a plastic bracket.
  4. Different batches of batteries to make a typical finished product and do life tests, lithium battery pack design specification experience summary of battery finished cycle test to get the actual cycle life.
  5. Verify battery performance at high and low temperatures. Different pack lithium battery manufacturers made of finished products and at high and low temperatures do different rate discharge tests, get the actual discharge curve.
