The significance of this study is to be able to negate FUD re: health effects of BEVs.
Some patients with cardiac rhythm problems have implanted devices to monitor and control heart rate. These devices are susceptible to interference from electromagnetic field variation (EMI). Changing electric current or voltage can cause EMI, and so with such electromagnetic induction in the normal functioning of a BEV, it was not unreasonable for cardiologists to want to confirm that these vehicles posed no risk to patients. Below is my summary/commentary. Any potential inaccuracies are mine.
Title: Implantable Cardiac Devices are Safely Shielded from Electric Automobiles
108 people with pacemakers and automatic defibrillators were studied in BEV’s to determine if the electromagnetic interference (EMI) from the flow of electricity in the vehicle would affect their implanted devices. Subjects were studied in all aspects of BEV use (rapid acceleration, regenerative braking, normal driving, charging, rapid charging). The EMI was strongest during rapid charging, but there was no evidence of interference with the subjects implanted cardiac devices. PHEVs were excluded from the patient evaluation because preliminary evaluation of PHEVs made it clear that flows of electricity, and therefore electromagnetic field variation, was too low in PHEVs to pose any risk. This was a European study; “the 4 most popular” BEVs were used (therefore I assume Tesla was in the mix). I don’t have access to more details.
