Scientists from the Perm National Research Polytechnic University have found that the level of electromagnetic radiation inside some Chinese hybrid cars can exceed safe limits by eight times. The study was conducted in different driving modes: during acceleration, braking, and while parked.
The highest values were recorded during acceleration: at these moments, the electric field voltage reached 200 V/m (volts/meter), which is considered dangerous to health. For comparison, a range of 10 to 25 V/m is considered safe, and the maximum permissible value is 25–40 V/m.
Experts explain that the sources of radiation in hybrid and electric cars are the traction motor, lithium-ion batteries, inverters, and chargers. Unlike traditional cars, where such sources operate periodically, in electric vehicles they are active constantly while driving.
During braking with recuperation, the radiation values decreased, but still remained high — 50–100 V/m. And during parking, the indicators dropped to 0-10 V/m, which is normal. Existing systems of protection against electromagnetic fields in such cars require improvement, especially for active acceleration and braking modes.
"The magnetic field behaved in a similar way: its intensity increased sharply during acceleration and braking, creating an additional load on the body," notes Alexey Shcheludyakov, Director of the Institute of Road Construction and Transport of PNRPU and Candidate of Technical Sciences.
Since the impact of electromagnetic fields is cumulative, long-term and regular exposure to high radiation can negatively affect the health of the driver and passengers, causing neurological disorders and depression, as well as increasing the risk of cancer.
