Background of VDA Battery Cells

The battery is the soul of an electric vehicle, and VDA battery module are the core of the battery. VDA battery cells are a battery cell standard defined by the Association of the German Automotive Industry (VDA), with the aim of achieving standardization and interoperability in the field of electric vehicles. In the past, electric vehicle manufacturers used a variety of battery cells, resulting in inconvenience in charging and maintenance, as well as low efficiency of the battery systems. To address this issue, the VDA battery cell standard size came into being.

Significance of VDA Battery Cell Standard Size

Improving Interoperability

VDA battery cell standard size aims to improve the interoperability of batteries. With a unified specification, batteries from different manufacturers can be interchangeably used in electric vehicles of different brands. This not only reduces the cost of maintenance and battery replacement but also popularizes charging facilities, improving convenience for users.

Enhancing Battery Performance

VDA battery cell standard size also helps enhance battery performance. The standardized size allows for better optimization of the battery structure, improving energy density and driving range. This makes electric vehicles more appealing and able to meet a wider range of travel needs.

Reducing Manufacturing Costs

The standardized VDA battery cell size also helps reduce the manufacturing costs of batteries. Manufacturers can mass-produce standard battery cells, thereby reducing production costs, which can ultimately translate into more affordable electric vehicle prices and accelerate the popularity of the electric vehicle market.

Specifications of VDA Battery Cell Standard Size

The VDA battery cell standard size specifies the range of length, width, and thickness of the battery. The standard size can be expanded or reduced according to the battery's needs to suit different models of electric vehicles. In the standard size, the position of the terminals and cooling holes of the battery is also fixed, making it easier for installation and cooling of the battery.

Impact of VDA Battery Cell Standard Size

The implementation of the VDA cell standard size has had a profound impact on the electric vehicle market.

Increasing Electric Vehicle Options

The VDA cell standard size allows electric vehicle manufacturers to flexibly choose battery suppliers, ensuring interoperability. This fosters market competition and encourages battery manufacturers to continually enhance product quality.

Reducing Maintenance and Replacement Costs

Standardized cell sizes make battery maintenance and replacement more economically efficient. Vehicle owners can more easily find suitable batteries, and repair services can offer more competitive prices.

Driving Electric Vehicle Market Growth

The implementation of the VDA cell standard size promotes the growth of the electric vehicle market. Improved interoperability and performance standards attract more consumers to consider electric vehicles, reducing greenhouse gas emissions and advancing sustainable transportation.

The VDA cell standard size is a significant initiative in the electric vehicle field, contributing to improved battery interoperability, performance, and reduced manufacturing costs. As the electric vehicle market continues to evolve, the VDA cell standard size will continue to play a crucial role in promoting more environmentally friendly modes of transportation, positioning electric vehicles as a dominant force in future mobility. Understanding the importance of this standard helps consumers better comprehend electric vehicle technology and contribute to a greener future. Click to learn more about the VDA355.

While electric motors are already recognizably superior to the classic combustion engine today, mobile electricity storage continues to present manufacturers with challenges. Of central importance here is the relationship between size as well as weight and storage capacity. As a result, the currently available battery technology often forces manufacturers to compromise on the range of their vehicles. TWIKE has managed to compensate for the disadvantage of the higher weight with advantages elsewhere.

At TWIKE, too, we have repeatedly been confronted with the question of how to reconcile limited space, desired weight and electric range by choosing the right energy storage system during the course of our development history, which now spans more than twenty years.

The limited space in the underbody proved to be a particular challenge in the search for the right energy storage system for the TWIKE 5. After the failure of an initially favored supplier and the resulting intensive research, the VDA format, which was initially ignored, finally presented itself as very suitable. Currently, lithium-ion technology is unrivaled in electric car applications. The capacity and voltage of a VDA module is 51 Ah at 44 V. The standard module can be connected in parallel and in series as a group structure to extend voltage and capacity up to 36 kWh at 352 V.

With a height of 108.5 mm, the alternative required only a modification to the sandwich structure of the battery box. Once again, it proved to be an advantage that TWIKE 5 can completely dispense with active cooling thanks to the low stress on the battery while striving for high durability. A surface heating system has only been integrated into the battery box for gentle charging at sub-zero temperatures.

Disadvantage of high weight turned into advantages

As a positive side effect of the necessary adjustments, the stiffness of the main frame has also increased. In addition, the battery electronics have been integrated into the sandwich body, reducing assembly times and freeing up additional storage space behind the seats. As a result of the switch to the new battery format, less small-scale tuning of the charging capacity is possible. The TWIKE 5 will therefore only be offered in two versions: one with an energy content of about 18 kWh and a range of about 250 km and a second with double the capacity and a range of 36 kWh or 500 km.

As a relevant compromise, the VDA format is recognizably heavier. However, we were able to offset the negative effects of the additional weight with aerodynamic modifications. Furthermore, the additional battery weight causes a lowering of the vehicle&#;s center of mass, additionally improving the TWIKE 5&#;s driving dynamics. &#;We have learned over the years to always face new challenges,&#; Möscheid explains. &#;After all, we are treading new paths with TWIKE, where we are a few steps ahead of the automotive industry in many areas and have to react correspondingly flexibly to short-term changes.&#;

When choosing the battery manufacturer, TWIKE is in the comfortable situation of being able to choose from different suppliers. to be able to select. The upcoming tests, which the batteries of the different manufacturers will undergo, will be the deciding factor as to who will be awarded the contract.
