Toyota has announced that it is developing a new technology where the battery degradation of its electric cars will be minimized after 10 years of use.
The goal set by the makers of the Japanese brand concerns the upcoming Toyota bZ4X, while it will also be applied to the next electrics. According to the data so far, the new technology developed by Toyota will allow to keep the capacity of the batteries even after 10 years of use at 90%.
More simply, a car that has a range of 500 km. when it is new, after 10 years of normal use it will be able to travel 450 km. on a charge, thus capturing the brand’s dedication to the reliability it offers with its models. With the elements so far, Toyota’s hybrid models (such as the C-HR), manage to maintain 75-80% of the original capacity.
The 1st generation plug-in hybrid Prius seems to retain 50-55%, with this percentage rising to 65% for the 2nd generation, as reflected in the graph below. It should be noted that now most companies give an 8-year battery warranty for at least 70% of the original charging capacity.
By the time these lines were being written, Toyota had not announced how it would be able to achieve this goal, since there are various practices. First by improving the chemical composition of the battery and then by properly managing the temperatures that develop within it, so that its elements remain in good condition over time.

According to the information so far, Toyota seems to have gone a lot deeper into the matter, since it is now working on new temperature sensors for each battery element and at the same time has greatly increased the quality requirements of the battery cells in order to prevent possible defects.
