FleetCarma has released the findings of a study conducted to understand the impact of new EV models on utilities grid networks over the past five years.

The impact of newer EVs is higher than previously projected.

The introduction of long-range EV models nearly doubled the charging load for each charging event from 4.5kW on average in 2014 to 9.7kW on average in 2019.

Other key findings from the EV Growing Pains study include:

The average per vehicle energy consumption per charge event nearly doubled from 9.01 kWh in 2014 to 17.96 kWh in 2019.

An increase in faster home charging with level 2 home charging stations increased from 63% in 2014 to 89% in 2019.

Increasing rates of EV adoption across North America combined with advances in batteries and charging technology are contributing heavily to the strain being put on global grid networks.

Residential energy distribution networks are at risk due to increasing long-range battery EVs.

Territory-specific load profiling and regulatory updated information specific to each service territory incorporating new EVs on the market will help utilities address challenges brought by new EV models.

The report is based on data from over 3,900 vehicles across North America, included 40 different EV makes and models, 761,096 charging sessions, 2.3 million hours of charging, 8,576 MWh of energy, and 28.9 million miles of driving data.
