If we want to achieve our climate goals, there is still a lot to be done. Nevertheless, we are already on the right track, as the new registrations of electric vehicles over the past few years show. But e-mobility also brings some challenges, in some cases it is not yet clear what we can do with old batteries. Some studies predict that by 2040 around 7 million tons of battery waste will be generated. The battery of an electric car has already reached the end of its life if it is only 80 percent of its original load. The car manufacturer Nissan has therefore developed a concept of how used electricity storage systems can continue to be used.
To do this, we have to look at Nissan’s production sites. Driverless transport systems (AGV), which are powered by batteries, are used in the various halls. These usually consist of lead-acid batteries that are harmful to the environment and only last around two years. The subsequent disposal is usually problematic and expensive. Batteries from your own electric car should initiate a turnaround here.
For this purpose, the used battery modules are removed from a Nissan Leaf and installed in the AGVs. Since an electric car from the group consists of There are modules and a driverless transport system requires 3 models, can 16 AGVs are powered by old leaf batteries. Worldwide Nissan has over 4. AGVs in use.
The new concept has many advantages: Batteries from electric vehicles can be reused, so the owner receives more for their old vehicle. In addition, lithium-ion batteries last up to 8 years and are easier to recycle. The charging time for the driverless transport systems decreases and harmful lead-acid batteries are completely deleted from the equation.
New problems require creative solutions. Nissan shows that it wants to take responsibility for the environment over the entire product life cycle and is thus taking a step in the right direction. For electromobility to be successful, it must make a contribution to environmental protection over decades. VW has also recognized this, for example, that the batteries of their own electric vehicles should be up to 95 Percent recyclable.
