I have a question: why does the battery heater begin warming the cells at -4F (it warms them to 14F) when the owners manual indicates reduced charging capacity below 32F and reduced battery performance below 14F
this is directly from the owners manual:
The Li-ion battery heater helps to prevent the Liion
battery from freezing and helps to prevent
significant reductions in the Li-ion battery output
when the temperature is cold. The Li-ion battery
heater automatically turns on when the Li-ion
battery temperature is approximately -4F
(-20C) or colder. The Li-ion battery heater
automatically turns off when the Li-ion battery
temperture is approximately 14F (-10C) or
higher.
The Li-ion battery heater uses electrical power
from an external source when a charger is
connected to the vehicle. The Li-ion battery
heater uses electrical power from the Li-ion
battery when the charger is not connected to the
vehicle.Why not have the battery heater maintain batt temp above 14F when plugged in?
And so is this:
When the ambient temperature is 32F
(0C) or less, charging time may be
longer than normal and the level to
which the Li-ion battery can be charged
may be less than at higher temperatures
At a start up temp of -4F most in the USA will never see any benefit from the system
why not have the system fire up at 14f if the car is connected to an EVSE?
why make a system standard in the USA when almost no one will see conditions where it will activate and benefit the user?
