Why EV batteries lose charge while parked
Engadget explains that battery checks, connected features and surveillance modes can draw power while an EV sits parked.
TLDR
A parked EV can lose charge even when no one drives it, Engadget reports. Its battery-management system checks conditions and may recharge smaller batteries; app requests, climate controls and security cameras can add to the drain. The amount varies by vehicle, settings and conditions. Cold weather can also lower the displayed range estimate without an equivalent amount of electricity being used.
