It is one of the essential parts of hybrid or electric models, but it is not unknown. The battery is the main engine of this type of vehicle and it is that it is its power supply. There are many doubts that arise about it, and therefore, in Seat they have wanted to solve the main doubts.
In the Volkswagen group they have not stopped evolving during all this time and they have been incorporating into their Battery technology that is based on lithium ion, being especially the chemical combination between nickel, manganese and cobalt (NMC). Each of these elements are located in separate cells, and that together with the electronics, the housings and the cooling system make the final perfect battery that is available in each vehicle that leaves.
We may consider that any type of battery is suitable for electric or hybrid models, but this is not the case. The main difference is in the energy storage capacity. In the case of the electric model that does not have a combustion engine, it is necessary that the battery has greater storage capacity, something only necessary to travel the same distance. On the other hand “The battery of a hybrid has about 100 cells, while that of an electric has about 300” says Francesc Sabaté, head of the Test Center Energy (TCE).
There are several factors that directly influence the useful life of the battery and it all depends on the same thing: depending on what use you make of the car it can last longer. In the group they have been working hard all this time to make it last as long as possible. To do this, they have carried out different tests that guarantee that minimum last 160,000 km or about 8 years warranty.
From the group they have indicated that if you want to guarantee the durability of the batteries it is necessary to reduce the number of fast charges, something that causes the temperature to rise excessively. The engineer of Seat S.A has indicated that it is necessary “sustain your state of charge between 40% and 80% it also helps to extend its useful life beyond the minimum warranty criteria“.
