Lithium ion battery pack production process includes 10 main assembly steps and QC steps.

Each battery pack will be 100% fully tested and before shipping out.

Incomming Material QC | Step 1

Material Sopt Inspection: Battery cells,BMS,Nickel sheet,cell frame,Battery Case.etc.

Cell Sorting | Step 2

Each battery cell will do voltage & Resistane sorting to make sure the battery cell voltage and inner resistance are in high consistency.

Cell Composing | Step 3

Composing the cells together in cell frame,
Cell frame is good for heat dissipation and better structure strength.

Cell Welding | Step 4

Manual Welding Machine: Welding the cells into various serial and parallel and form a battery pack manully, this way for sample & small quantity order.

Automatic Welding Machine: Welding the cells into various serial and parallel and form a battery pack automaticlly, this way for high quantity order.

Wiring & Soldering | Step 5

Wiring and slodering the BMS to the battery pack.BMS tester tests BMS performance

Insulation | Step 6

Use insolative Paper/PVC/Epoxy plate to wrap the battery pack for electricity insulation purpose

Aging QC Test | Step 7

Each battery will do aging test;
Aging test means to do full charge/discharge cycle to see the battery pack performance and keep all performance data for tracking.

Housing Assembly | Step 8

Put the aged lithium battery pack into the plastic/metal housing.

Comprehensive QC Test | Step 9

Each battery will do comprehensive test before packing to double check the battey charge/discharge/BMS funciton.

Packing | Step 10

Put lithium ion battery pack into UN box or regular box, then stack on the pallet.
