ASSEMBLY LINES FOR BOTH LFP PRISMATIC 

AND NMC CYLINDRICAL CELLS

[CODE NO.4319]  

Battery Pack: Energy storage device, which is comprised one or more cells or modules electrically connected together inside a mechanical pack with electronics as required for safety and operation.

The battery pack may incorporate a protective housing and be provided with terminals or other interconnection arrangement. It may include protective devices and control and monitoring required for safe and proper operation. A typical example of a battery pack may be built by using 6s2p Lithium-ion module. It may provide detailed information (e.g., cell voltage, temperature, capacity) to a higher level battery system management device.

Battery management system or unit (BMS, BMU): Electronic system associated with a battery which monitors and/or manages its state, calculates secondary data, reports that data and/or controls its environment to influence the battery's performance and service life and has the functions to cut off in case of abnormal conditions (e.g., over charging, over current and overheating and charge balancing between cells or parallel cells blocks).

Depending on the application and its size, the function of the BMS/BMU can be assigned to the battery cell, module, string, pack or system and equipment using the battery. A common implementation is a BMS/BMU made of several electronic modules located at different levels of the system.

A battery management system (BMS) is sometimes also referred to as a battery management unit (BMU).

Battery System: System which incorporates one or more battery cells, modules, strings or battery packs and has one or more BMS or BMU. The battery system is generally defined for high power and capacity batteries made of several battery strings or packs of blocks or modules it may include cooling or heating units and gas exhaust arrangement.

Lithium Ion Battery Cells

Lithium-ion (Li-ion) batteries, also known as secondary batteries, are rechargeable batteries in which lithium ions move from the negative electrode, usually made of carbon, to the positive electrode made of a metal oxide (nickel, manganese and cobalt) during discharge, and back when charging. The electrolyte is typically a mixture of organic solvents, such as ethylene carbonate, dimethyl carbonate or diethyl carbonate, containing complexes of lithium ions, such as lithium hexafluorophosphate (LiPF6), lithium hexafluoroarsenate monohydrate (LiAsF6), lithium perchlorate (LiClO4), lithium tetrafluoroborate (LiBF4) or lithium triflate (LiCF3SO3).

Li-ion batteries have high energy density, tiny memory effect and low self-discharge. They are commonly found in home and portable electronics (e.g. laptop computers). They are also growing in popularity for battery electric vehicles or aerospace applications and are becoming a common replacement for many applications that have been using historically lead acid batteries.

Characteristics of lithium ion battery cells 

The lithium ion battery cells have the following main characteristics: 

? High gravimetric and volumetric energy density 

? Higher voltage than aqueous technologies (> 2V) 

? No memory effect and negative effect of partial state of charge (PSoC) 

? Moderate environmental impact depending on chemical composition and features (less cobalt, less toxic electrolyte, better recycling.) 

? High rate discharge 

? Fast charge and long life cycle 

? Safety 

? Wide temperature ranges

Some advantages of Li-ion batteries are: 

1. High specific energy and high load capabilities;

2. Long cycle and extend shelf-life

3. Maintenance-free;

4. High capacity, low internal resistance, good coulombic efficiency

5. Simple charge algorithm and reasonably short charge times;

6. Low self-disch

However, their limitations are:  

1. Circuit protection requirement to prevent thermal run-away if stressed

2. Degradation at high temperatures and when stored at high voltage;

3. No rapid charge possible at freezing temperatures
