On the right, under black electrical tape, is a sensor for ambient temperature taken from the metal pole.
The first issue, related to ambient temperature, is determining where to locate the sensor.
In fact, the body temperature (or ambient temperature) makes no difference at all.
As they enter hibernation, their temperature drops but is carefully maintained, using their fat reserves, at just above the ambient temperature.
Unlike most terrestrial animals, aquatic animal species used for human consumption are poikilothermic, meaning their body temperatures vary according to ambient temperatures.
Due to the low cost of the battery cells and excellent performance at ambient temperature, Lithium-ion (Li-ion) battery is a promising technology for propulsion applications.
