By now it is clear that electric powered automobiles (EVs) offer drivers a assortment of benefits—and several nations around the world, together with the US and practically all EU member states, provide incentives for EV adoption. Then why are so handful of drivers trading in their gas-powered cars for EVs?
1 crucial factor is assortment anxiety—drivers’ concerns that they may perhaps be stranded without the need of power if they journey a extended distance and cannot track down a charging station. A different concern is their confined knowledge of how the EV charging course of action may well have an impact on their every day lives. We imagine that driver perceptions about the time and effort necessary to cost an EV, as opposed to fueling an internal combustion engine (ICE) auto, is one particular of the most critical aspects blocking folks from producing the switch.
The Auto AI crew at BCG recently performed an ground breaking simulation to ascertain the added time and effort ICE drivers will experience when switching to an EV. Drawing on an intensive entire body of driver and EV charging data, we ended up ready to determine the groups of ICE motor vehicle homeowners with a greater diploma of readiness to switch. The insights from this method can support automakers goal prospective EV shoppers and can inform EV infrastructure planners working to improve the community charging encounter.
Our Framework for Investigation: A Handful of (Million) Auto Excursions in Texas
The team’s evaluation was dependent on facts bought from a foremost supplier of connected automobile info. It signifies 15 million journeys made by 10,000 related passenger autos through Texas—one of the biggest US states with a sturdy combine of city, metropolitan, suburban, and rural locations.
Working with the simulations to produce styles from the facts, we segmented drivers into 6 archetypes to determine their driving behaviors and needs—especially in phrases of EV length vary and obtain to community charging networks. Our simulations emphasize various combinations of charging community improvements in phrases of density and speed and how these elements impression EV readiness of the archetypes. For case in point, drivers who make repeated, extended spherical journeys gain a lot more from improvements in network pace for the reason that they will have to cost their autos when enroute. (See “Study Methodology and Assumptions” for far more details.)
EV Distance Vary Assumptions
- EV length ranges observed in the write-up refer to the formal ranges identified by the US Environmental Defense Company (EPA).
- Our simulations are based mostly on the powerful range of the auto. This figure is about 30% decrease than the EPA ranges to acquire into thought the simple fact that the battery is charged only partially, as properly as the effects of weather conditions disorders and driving habits.
- The simulations have been applied with the best amount of granularity, looking at the speed and temperature of every journey in the sample. In the sample, 40% of the full length has been operate at outdoors temperatures bigger than 35 C° or lessen than 15 C°, with temperature manage consuming more battery electricity. Speed calculations generate comparable outcomes: 40% of the complete distance has been run at a speed bigger than 70 km/h.
EV Readiness Simulation Assumptions: Technological innovation
- The simulation versions a driver swap from an ICE vehicle to an EV with a 70 kWh battery, 500 km EPA selection, and 14 kWh/100km performance (comparable to the Tesla Product 3).
- Variety 2 chargers, which comprise 80% of the community in the sample, are assumed to have a charging speed in Texas of 12 k/W. The remaining 20% are quick-charging Style 3 stations, like Tesla SuperChargers.
- Time spent ready to use a charger at public charging stations is assumed to be negligible, reflecting lower levels of EV penetration.
EV Readiness Simulation Assumptions: Demographics and Behaviors
- Centered on US Census facts, we assumed that 35% of folks in superior-density parts are living in single-loved ones residences and 80% of people in mid-low density areas reside in single-spouse and children residences.
- By upgrading individual garages and parking lots, 85% of solitary-loved ones household homes and 25% of condominium households can set up residence charging units.
- Motorists are inclined to proactively recharge their cars and trucks at desired destination-related places if the charging station is significantly less than 500 m absent.
- Motorists will stroll between charging stations and their ultimate locations at a speed of about 5 km/h.
- Where charging stations are integrated with micro-mobility, motorists will be willing to journey 2 km to a charging station, at a speed of 15 km/h.
- Workplace charging stations are described as non-residence places exactly where a motor vehicle is parked for extra than 4.5 hours for at the very least 100 weekdays per yr.

Time and Exertion: The Keys to Driver Readiness
Compared to filling up the tank of an ICE automobile at the local fuel station, charging an EV usually takes far more time—and charging networks are not as commonly readily available. Hence, EV homeowners advantage from charging at destinations exactly where they generally go away the car for extended periods, this sort of as at house, perform, or parking loads and garages.
For our simulation, we approximated the more time and exertion it will take to cost an EV, considering actual driving styles and situations. We incorporated the distance to the charging position closest to each driver’s vacation spot, the charging speed for that position, the time it will take to demand a motor vehicle, and the will need to interrupt a excursion and wait for the charge. We also evaluated the impression of neighborhood temperature disorders on EV assortment, as heating and cooling a car’s interior can drastically lessen battery period.
Our main assumption for deciding EV readiness is that motorists are completely ready to swap to an EV if the additional time and hard work (web time in excess of the time used fueling an ICE) is less than 5% of the whole time spent driving. For the drivers inside our dataset, who drive an regular of 11 hours for each week, the five percent threshold translates to about 30 minutes.
Charging Location Underlies the Time+Exertion Variable
Our simulations ended up performed underneath two eventualities. The community charging situation applies to motorists who can only demand their EVs in publicly obtainable stations, such as individuals in a browsing centre or freeway relaxation cease. In the non-public state of affairs, drivers can cost their autos at residence, and only have to have general public chargers on extended journeys. (Note that the ability to cost an EV at get the job done is not provided in the simulations.)
In simulations beneath the community charging scenario, only 3% of drivers are EV prepared, even with a rather higher-variety (500 km) electric vehicle. (We utilised 500 km as the base car array as it is equivalent to the selection of the Tesla Product 3, a leading vendor in the US.) When the simulations are established to the non-public, at-dwelling charging circumstance, the proportion of EV-prepared motorists jumps to 71%—again, assuming folks possess 500 km variety EVs. Dropping the EV range to 300 km, our simulations even now come across that in excess of 50% of personal-charging motorists are completely ready to switch from an ICE. (See Show 1.)
