Abstract: Electric vehicles indicate charge levels in different ways. A lighting control module is communicatively is configured to illuminate an exterior light of an electric vehicle to indicate a charge status of a battery for the electric vehicle. The charge status is indicated based on varying an intensity of the exterior light, based on illuminating a subset of the exterior lights, and/or based on an animation.

Abstract: A controller of a host system executes a method for detecting an external AC electrical device. While an AC charging inlet of the host system is electrically connected to the device via different vehicle-to-live (V2L) and jump-charge connections, the controller detects a control pilot voltage and a proximity voltage. When the control pilot voltage is 0V, the controller determines whether entry conditions are satisfied indicative of a desire to offload power from the host system to the device. When the entry conditions are satisfied, the proximity or control pilot voltage are modulated to generate a modulated voltage signal, which the controller compares to an expected voltage indicative of the device. Power is offloaded to the device when the modulated voltage signal matches the expected voltage.

Abstract: Techniques described herein relate generally to determining and applying threshold discharging C-rates for battery cells in low temperature environments. To combat internal resistance within a battery cell at low temperature, heat may be generated within a battery cell via a high discharge C-rate. A higher discharge C-rate may cause more heat generation with a battery cell and the higher temperature may mitigate the low temperature environment. As a result of the heat generation, a battery cell's capacity may be increased. Techniques described herein may identify, for a particular low temperature (0 degrees Celsius and below), a threshold discharge C-rate that if a battery cell is discharged above the threshold, the effect of temperature rising would be more dominant than the effect of the internal resistance and more capacity would be obtained from the battery cell.

It may be detrimental for a high-voltage battery in a parked vehicle to be exposed to extreme temperatures for an extended period of time.
