Battery pack assembly

Specially adapted battery packs are of great advantage, especially in industry. When assembling our battery packs, we go through an extensive quality assurance process to achieve a higher safety standard.

 

Selection of the chemical material and selection of the cells

To guarantee a product that meets modern standards, the choice of the chemical system and the subsequent selection of the respective cells is crucial.

We offer a wide range of systems (e.g. Li-Ion, LiFePO4, LiPo, NiMH, etc.).

The cells of the system are then fully automatically selected according to internal resistance and voltage level, grouped according to their respective level and processed into a battery pack.
In this way we ensure a homogeneous unit to ensure the stability and service life of the batteries.

Dimensioning of the battery pack and arrangement of the cells

The cells are then dimensioned in special containers, the so-called cell racks, and prepared accordingly for welding.

Welding

In the next step, the suitable welded connectors are selected and cut to a suitable format.

The welding is then carried out either automatically or manually.

Our semi-automatic spot welding machine (shown) welds battery packs from both sides simultaneously in highest quality. This means that even series production can be processed quickly.

We also offer all our welding machines for sale, please contact us.

Protection electronics

Our rechargeable batteries are equipped with a specially developed and installed protection electronics, which protects them against

  • Overload,
  • Deep-discharge,
  • Short circuit
  • extreme temperature conditions protects
  • and individual cells.

After careful selection of the appropriate protective electronics, these are attached to the battery pack.

Insulation

Now both the cross-section of the cable for the current of the battery and the respective material of which the cable is to be made (e.g. PVC, rubber, silicone etc.) are determined.

Then the battery pack is sheathed with a so-called GFK insulation.

This material is reinforced by glass fibre and serves as mechanical protection to insulate the battery.

Fabrication and shrinking

The connectors of the battery pack are assembled according to the requirements.

Afterwards the shrinking of the battery pack can be started.

Adaptation of firmware and quality assurance

The firmware of the battery pack can now be individually adapted to the customer's wishes.


At the end of the process, numerous load tests are carried out and a quality assurance acceptance test is carried out to ensure that the battery pack functions properly.

Example: Internal structure of a battery pack

  1. Cellracks
  2. Shape of the welded connectors
  3. Additional insulation on the positive pole
  4. Protection electronics
    4.1. Temperature switch
    4.2. Temperature sensor
  5. Hard insulating plate between batteries and protection electronics

Replacement

Tool battery packs

Batteries that were thought to be dead can be revived by changing cells.

In this way we contribute to a longer use of the batteries and thus also to the protection of the environment.

We offer cell exchange for all tools (e.g. cordless screwdrivers, lawnmowers, golf trolleys etc.) and have replacement parts for a large number of models in stock.

Emergency lights

We carry the most common Ni-Cd, Ni-MH and Li-Ion emergency lighting batteries.

If you need a custom-made product, we can manufacture the required battery packs from a wide variety of cell types.
For this purpose we have the most common cells such as 18650, AA/Mignon, Sub-C, Baby/C or Mono/D in stock. But also special sizes like 1/3AA, 1/2 Sub-C, 4/3A and many more are possible.

E-Bike-Careservice

For E-Bikes we offer a special E-Bike battery careservice.

The battery of your electric bike does not last much longer? Is it deeply discharged or completely defective? We can determine the capacity of your e-bike battery for you using a test machine.

We will be happy to advise you and provide you with a cost estimate for a cell exchange. We install brand name cells in the existing housing of your e-bike battery. In most cases, stronger cells with a higher capacity can be used, thus increasing the range per battery charge.

Please contact us for more information.
