Voltage fluctuation

[securityguy]

Voltage is directly proportional to resistant (V=IR) and resistance increases with temperature due to increased vibrations of the molecules inside the conductor. Therefore voltage increases as temperature increases.

Understood...but why am I now seeing decreased voltage while driving my eT? I am not concerned at all as all voltages are within normal operating parameters, I just find it interesting.

My understanding is your e-Torque is using your 48V lithium battery pack behind the rear seats in your cab. Lithium is also greatly affected by temperatures especially lithium-ion technology.

Our Trucks have a smart alternator on them so since your 48V battery pack is holding it's charge better in the warmer climate there is less demand on the alternator to provide juice to the pack and so the alternator runs at a lower voltage which takes less power from the engine and is suppose to increase your mileage.
