Gotta stick with the same instrument when you're comparing measurements. Thermistors can be notoriously badly calibrated and thus not reliable.

No. Temperature of handheld IR-thermometer matters more than thermistor production tolerances.
Short range EVs <30kWh -- Medium range: 30-60kWh -- Long range: >60kWh
Charging: Trickle <3kW -- Normal 3-22kW -- Fast 50-100kW -- Supercharging >100kW
