Does electron charge or body temperature change at relativistic speeds?

[abrowaqas]

what will happen to the Charge of an Electron and the temperature of body if the body is speeds nearer to the speed of light. since in many books Einstein relativity discuss only change in Mass , Length and Time.. what about the other two fundamental quantities that is Charge and Temperature?

Charge is frame-invariant.
Temperature is a controversial subject, to my best knowledge, the subject is not settled since it depends heavily on the definition of temperature.
