Lithium battery processing, lithium battery PACK manufacturers

Processing, lithium-ion batteries and lithium battery PACK manufacturer production, including product versatility, from civilian digital technology, communications products to the mechanical equipment to the special equipment safety are applied in large quantities, such as different goods must be of different types of work voltage and capacity, and application of many parallel of lithium ion batteries battery circuit, Lithium battery based on the modification of the protection circuit, chassis, export formed by the use of batteries called PACK. PACK can be a single battery, such as cell phone battery, digital camera battery, MP3, MP4 battery, etc., or a series or parallel battery, such as notebook battery, medical device battery, power supply system, battery of battery car, backup power supply, etc.

1. Composition of lithium battery PACK:

PACK contains a PACK composed of battery pack, battery protection plate, outer packing box or casing, export (including RF connector), key switch, power indicator, EVA, highland barley paper, plastic bracket and other auxiliary materials. PACK's external characteristics are determined by application. Packs come in many varieties.

2. Production process of lithium battery PACK:

3. Characteristics of lithium battery PACK

Has a complete function, can be directly used.

Diversity of types. There are many packs that can implement the same business requirement.

The battery PACK specifies that the battery has a relatively high degree of consistency (volume, internal resistance, operating voltage, discharge curve, life).

The circulating system life of the battery PACK is shorter than that of a single battery.

When applied under limited conditions (including charging and discharging current, charging method, temperature, ambient humidity standard, vibration condition, bearing level, etc.), the lithium battery PACK battery protection panel shall have the function of charging balance.

High-current and high-voltage battery packs (such as battery car batteries and energy storage systems) are required to be equipped with communication system buses such as intelligent battery management system (BMS), CAN and RS485.

The battery PACK has very high requirements on the charger, and there are some requirements to complete the communication with the BMS. The purpose is to make each battery operate normally, give full play to its stored kinetic energy, and ensure the safe and reliable use.

4. Lithium battery PACK design

Understand the application requirements, such as application scenarios (temperature, humidity, vibration, corrosion resistance, etc.), service duration, charging, charging and discharging modes, electrical parameters, export methods, and service life requirements.

Select the battery protection and circuit board according to the requirements of the application, to meet the specifications, weight regulations.

The outer packing is reliable and meets the requirements.

The production process is simplified.

Optimal control of planning scheme.

The cost is minimized.

The inspection is easy to complete.

5, lithium battery use specification!

Do not invest money in fire or near pyrogen applications!!

The positive and negative results cannot be immediately joined together with metal materials.

Do not exceed the range of battery temperature application.

Do not squeeze the battery hard.

Use a special charger or charge it the right way.

Please recharge the battery every three months when it is idle. And in accordance with the storage temperature.
