[quote:Anonymous Coward 76114335:MV80ODA2NTk4Xzg3Njc4NDEzX0MxQTg5MERF] Possible to have electronic controlled thermoregulation that insinuates batteries when vehicle is not being used, such as when garaged. Then, redirect some frictional heat through a heat exchanger built into insulative housing, which will be governed by a temperature sensor to maintain optimal ambient temp of battery electrochemistry throughout stop start. So, the only additional energy consumed will be initial warming up period, should heat gradient favour external ambient temp. Similarly to old school diesel tech, where glow plugs were used to warm up cylinder bores before actually cranking engine, to assist in autoignition. Likewise, the batteries can be warmed up. However, to minimize shortening lifespan of batteries, they really should never be stored in temps below their optimal range. So, if the vehicle is being stored in extreme temps, the batteries should be stored in an environment with climate control. Since this becomes costly to achieve, it is unlikely to be incorporated into design, especially if business model is to maximise profits by selling you new batteries often as possible. Regardless, the end user consumer will need to isolate batteries and remodel if wanting maximum longetivity, which is still time and money. Easier, cheaper and more practical to use combustion or compression engine technology. [/quote]
