Cars
Sooner or later in life, everyone has to deal with one low battery that prevents you from starting the car: usually to solve the problem it is sufficient to have another car available that can start and Cavi to connect the two batteries together.
What happens instead on an electric car like the Tesla Model S, if the battery is completely discharged? Today he tells us about it James May, famous auto journalist and one of the founders of the online community DriveTribe, in the video that we report at the bottom.
The Tesla Model S is equipped with two batteries: on the one hand there is the battery pack which powers the car, on the other there is a classic one 12V battery which allows the opening of the car and keeps the various settings of the car saved in the memory. The latter, after long weeks of inactivity in the garage, is downloaded even though the car was connected to the current: the charging system in fact allows this battery to be recharged as well, but stop doing it when the largest battery is fully charged 100% and needs no additional energy.
This setting meant that the car, stopped for a long time, had the main battery 100% charged but the fully discharged auxiliary, as it continued its work of feeding the on-board computers.
Understanding the problem, May had to figure out how to get to the auxiliary battery to plug it in and be able to use his Tesla again. It was necessary to reach the emergency releases of the front hood – hidden behind the plastic covers of the front wheel arches – and remove several plastics before spotting the auxiliary battery that needed current, an operation that not everyone would be comfortable doing in the garage at home, and which one would expect to have to on a car of the caliber of a Tesla Model S.
The whole operation took approx an hour, and has created some annoyance in the English journalist, who is keen to warn us about this design flaw of the Model S.
