Introducing the Knowledge of Battery Pack

Battery Pack consists of battery , bus-bar, soft connection, protective board, outer packing, output (including connector), highland barley paper, plastic support and other auxiliary materials. TOB New Energy offers a full set of battery pack equipment for battery manufacturming.

The characteristics of the battery PACK

The battery PACK requires the battery to have a high degree of consistency (capacity, internal resistance, voltage, discharge curve, life).

The cycle life of the battery PACK is lower than that of a single battery.

Use under limited conditions (including charging, discharge current, charging mode, temperature, etc.)

Lithium battery PACK formed after the battery voltage and capacity has been greatly improved, must be protected, the charge balance, temperature, voltage and over current monitoring.

The battery PACK must meet the voltage and capacity requirements required by the design.

The process of battery PACK

the PACK of the battery can be realized in two ways. One is through laser welding or ultrasonic welding or pulse welding. This is a commonly used welding method.Second, contact through elastic metal sheet, the advantage is no welding, easy to replace the battery, the disadvantage is may lead to poor contact

The requirement of the battery pack process

During the process of PACK, such as nickel sheet, copper-aluminum composite bus, copper bus, total positive and total negative bus, aluminum bus, and copper soft connection, aluminum soft connection, copper foil soft connection, etc.The processing quality of busbar and soft connection needs to be evaluated from these aspects.

Whether the material material is composite requirements, bus material is not up to the standard will increase the resistivity, especially need to confirm the composite ROHS related requirements.

The key size processing is in place.The out-of-tolerance of key dimensions may lead to insufficient safety distance between high voltage devices during the assembly process and cause serious safety risks.

(3) soft connection of the hard zone bonding force and soft zone stress absorption.

(4) whether the actual processing of the soft connection and bus through the flow capacity of the design standards, whether the insulation of the thermoplastic casing is damaged.

We are TOB NEW ENERGY, we are not only provide the battery equipment and materials we will also provide the knowledge of the battery.
