Electric cars and plug-in hybrids boast much lower emissions than models with combustion engines. But they are expensive, since their batteries use scarce materials (problems with lithium are known) and they are potentially dangerous.
And in this position is precisely the Volkswagen Group, which has just announced that it could call up to 124,000 vehicles of the brands Audi, Porsche and Volkswagen. These are cars whose batteries have used toxic cadmium. Apparently, one of the suppliers of the industrial group would have used heavy metals to manufacture the components of the chargers of the electric cars and in them cadmium was detected, something that is prohibited in the production of cars (although it has other industrial uses).
On July 20, the presence of 0.008 grams of cadmium was detected during an internal inspection in those chargers that use electric and hybrid. Apparently, the production of these models stopped and work is being done on finding another supplier. But there are 124,000 models in circulation with this problem (manufactured six years ago).
The users of these cars should not worry. There is no danger, since the chargers are installed inside a solid casing inside the charger, which in turn is covered by another solid layer that completely isolates it from contact with the atmosphere. The problem is that the presence of this material does not comply with the European legislation on vehicle recycling at the end of its useful life.
Now it remains to be seen if a call to review is made the Federal Motorized Transport Authority (KBA) is analyzing whether it should be carried out, which would affect models manufactured between 2013 and July 2018. The image of the group, still recovering from the loss of credibility caused by the scandal to manipulate emissions of its diesel engines, you could resent it. We will see how they solve this mess and if the call to review to replace that component is made worldwide or only in Germany
