Here's a NERL report that has some interesting facts.

Abstract—Following a hot or cold thermal soak, vehicle climate control systems (air conditioning or heat) are required to quickly attain a cabin temperature comfortable to the vehicle occupants. In a plug-in hybrid electric or electric vehicle (PEV) equipped with electric climate control systems, the traction battery is the sole on-board power source. Depleting the battery for immediate climate control results in a reduced charge-depleting (CD) range and additional battery wear. PEV cabin and battery thermal preconditioning using off-board power supplied by the grid or a building can mitigate the CD range reduction and battery life impacts of climate control. To quantify the impact, the National Renewable Energy Laboratory (NREL) applied the Powertrain Systems Analysis Toolkit vehicle simulation program to develop and validate models of three relevant PEV platforms: a blended plug-in hybrid electric vehicle (PHEV) with a 15-mile (24-km) electric range (PHEV15), a series PHEV with a 40-mile (64-km) electric range (PHEV40s), and an electric vehicle with a 100-mile (161-km) electric range (EV). Second, NREL surveyed literature and test data to develop representative air conditioning and heater load profiles. Next, NREL simulated PEV performance with and without thermal preconditioning over the UDDS and HWFET drive cycles, and for three different ambient temperature scenarios. Finally, battery wear was characterized using a physically justified semi-empirical lithium ion battery life model. This analysis shows that climate control loads can reduce CD range up to 35%. However, cabin thermal preconditioning can increase CD range up to 19% when compared to no thermal preconditioning. In addition, this analysis shows that while battery capacity loss over time is driven by ambient temperature rather than climate control loads, concurrent battery thermal preconditioning can reduce capacity loss up to 7% by reducing pack temperature in a high ambient temperature scenario.
