September 27, according to foreign media reports, it is well known that electric vehicles are not only cheaper than fuel vehicles, but also beneficial to the environment and reduce carbon and other gas emissions. At the same time, charging when electricity demand is low at night helps to solve the problem of load imbalance in power grid day and night.

But a new report by Stanford University researchers shows that charging electric cars at night can destabilize the power grid and generate more carbon emissions than during the day.

However, foreign media also pointed out in the report that there are shortcomings in this report by Stanford University researchers. They only studied the charging of electric vehicles in California, which seems to be negligible, but this research needs to be considered.

According to foreign media reports, the power grid in California, where Stanford University is located, relies on solar and wind energy, but solar energy can only generate electricity during the day, while California's power grid relies on fossil energy at night, which means that if electric cars are heavily charged at night, California's power grid needs to consume more fossil energy to ensure power supply, which will inevitably lead to more carbon emissions and affect the stability of the power grid.

Although Stanford University researchers report that night charging of electric vehicles affects the stability of the power grid and produces more carbon emissions, it is only applicable to areas that rely on wind and solar energy, foreign media also pointed out in the report, in areas that rely on renewable energy, energy storage systems need to be more widely coordinated with renewable energy.
