Pois, tens razão.Devem ter pensado nisso, mas desvirtuava o projecto e eliminava o elemento diferenciador.

Together with our partner ElringKlinger, we have developed a liquid-cooled lithium-ion battery specifically for the Sion. Our battery consists of 192 cells. We have taken the different technologies for lithium-ion batteries into consideration and also the various possible cell formats, and opted for the prismatic cell shape. Among other advantages, it offers very good cooling characteristics. Liquid cooling allows the temperature of the battery to be precisely controlled, thus extending its lifetime.
As the temperature of the battery will be precisely controlled, we at Sono Motors do not see this as a critical topic.
