英文回答：
Battery Production for Electric Vehicles.
The production process for electric vehicle (EV) batteries involves several key steps:
1. Raw Material Processing.
Raw materials such as lithium, cobalt, nickel, and manganese are mined and refined into battery-grade materials.
2. Electrode Manufacturing.
Battery electrodes are made by mixing active materials with conductive materials and binding agents. These mixtures are then coated onto metal foils.
3. Cell Assembly.
Electrodes are stacked together with a separator to form a cell. The cell is then sealed in a housing.
4. Module Assembly.
Cells are grouped into modules, which are interconnected to provide the desired voltage and capacity.
5. Pack Assembly.
Modules are assembled into a battery pack, which is the complete power source for the EV. The pack includes cooling and safety systems.
6. Battery Management System (BMS)。
A BMS is installed to monitor battery performance, protect against overcharging and overheating, and optimize charging and discharging.

电动汽车电池生产工艺流程。
电动汽车（EV）电池的生产过程涉及几个关键步骤：
1、原材料加工。
原材料，如锂、钴、镍、锰等，被开采并精炼成电池级材料。
2、电极制造。
电池电极是通过将活性材料与导电材料和粘合剂混合制成的。然后将这些混合物涂覆到金属箔上。
3、电池组装。
电极与隔板叠放在一起形成电池。然后将电池密封在一个外壳内。
4、模块组装。
电池组合成模块，相互连接以提供所需的电压和容量。
5、电池组装。
模块组装成一个电池组，这是电动汽车的完整动力来源。电池组包括冷却和安全系统。
6、电池管理系统（BMS）。
安装 BMS 以监测电池性能、防止过度充电和过热，并优化充放电。
