Stanford Study Highlights Why EV Charging Habits Need to Evolve

Electric vehicles are leading the race to electrify road transportation and are luring drivers to do so. According to researchers from Stanford University, if changes are not made before zero-carbon emissions targets for electric vehicles are achieved, present charging practices for electric vehicles would be untenable for the electrical grid.

Presently, there are almost 16.5 million EVs on the roads worldwide. This figure is expected to increase to 300 million by 2030 following a strategy to have zero carbon emissions by 2050.

The researchers, who concentrated on the western American geographical area, discovered that without big expenditures and adjustments in charging behaviors, the power grid will encounter major strain when the adoption of electric vehicles reaches 30% to 40% on U.S. roads.

The study team conducted a study to examine the charging habits of residents in 11 states in western regions and the effect on the electrical grid. According to Stanford’s findings, utilizing normal chargers is so time consuming that vehicle owners frequently have their electric cars charging throughout the night, and during the evening hours, when many people get home after work, energy consumption spikes as they tend to switch on several other electric appliances, thus straining the electricity grid further.

Ram Rajagopal, a cosenior investigator in the study, urged regulators to take into account utility prices that support daytime charging and stimulate charging network investment. They discovered that charging during the day would lessen carbon dioxide emissions in addition to relieving grid stress.

For instance, California produces extra electricity primarily due to its solar capacity in the mid-morning as well as early in the afternoon. According to the analysis, if people would charge their EVs during those hours, the less expensive solar energy might be utilized rather than wasted.

The sun’s energy is receiving significant investment in several areas. For instance, the REPowerEU program predicts that by 2029 solar power panels will be installed on every European household’s roof as part of the EU’s current solar power policy. It will be crucial to utilize this midday electricity as the globe transitions to sustainable power.

The authors highlighted the potential significance of technologies such as vehicle-to-grid charging, also known as V2G charging, which enables power to flow both ways between EVs and the power grid. V2G charging will help electric drivers lower their overall ownership costs by increasing the energy capacity in the grid during times of high-power demand, reducing local traffic, and providing a safety net against intermittent power sources by allowing owners to sell extra power in the battery back into the grid.

Given the suggestions in this study, EV startups such as Rivian Automotive Inc. (NASDAQ: RIVN) may soon have to start distributing educational material explaining when their customers should charge their vehicles so that rapid electrification doesn’t cause grids in different locations to be unduly strained.
