Does the electric car charge in the room when there is no radiation?
Battery car battery is generally used in the VRLA battery, this battery is the use of chemical energy into the principle of electricity, in the charging process is not a radiation problem.
Before the answer to explain the radiation problem, all the objects in nature, as long as the temperature above the absolute temperature of zero, all with electromagnetic waves and particles in the form of constant flow of heat, this way of transmitting energy is called radiation The
So that there is anything there is radiation, the difference is that the degree of radiation on the human body is not harmful.
Tram charging is only a simple current changes, just like the home open lights, to the same flashlight, the impact on the human body is minimal
Theoretically there is electricity there is radiation, but the battery charge radiation can be ignored, will not affect the child.
It is now the battery are lead-acid batteries, long-term concentration in the non-ventilated room may be part of the electrolyte or heavy metal release, please note that window ventilation!
