The temperature sensor connected to the Quattro is used for temperature compensation of the charging. It is not used for alarms, a readout is not available either. When connected to a CCGX, then the temperature sensor can be assigned as a battery temperature sensor and then the values used for Shared Temperature sense for example, the values ...
Never allow the Battery to fully discharge. Even when Model 3 is not being driven, its Battery discharges very slowly to power the onboard electronics. The Battery can discharge at a rate of approximately 1% per day, though the discharge rate may vary depending on environmental factors (such as cold weather), vehicle configuration, and your selected settings on the …
Lithium-ion batteries used in EVs, perform optimally within a specific temperature range—ideally between 26-35°C (68 to 86°F).More than 35°C (86°F) can lead to higher rate of degradation of the battery components, which impacts long and short term battery longevity.. Important: EV battery replacement can cost $1000s.To avoid high-voltage battery …
The high temperature alarm will beep and LED blinks when the temperature of the device increases abnormally. This simple over heat alarm is to monitor heat generating devices such as motor, inverter etc. The circuit is a simple astable multivibrator using the low power CMOS timer IC 7555 which is the low power version of the popular 555 IC.

Most protection circuits cut off if voltage greater than 4.3 V or temperature greater than 90 °C is reached. Below 2.50 V/cell the battery protection circuit may render the battery unchargeable with regular charging equipment. Most battery circuits stop at 2.7–3.0 V/cell. So to achieve a full state of charge you''d normally want to aim at 4.2V.
