What are the nominal voltages of automotive electrical products? What is their meaning?
Most cars use 12V voltage, mostly with 24V truck.
Automotive electrical products, the voltage is the main power supply system voltage and power system voltage, the general power supply system voltage (battery) voltage of 12V and 24V. And the output voltage of the generator is 14V and 28V. The voltage of the electrical system (electrical) is standard 14V and 18V. There are power supply system voltage and the voltage of the electricity system is not the same. Such as some engineering vehicles battery voltage is 24V, starter for the 24V, while the other lighting system voltage is 12V, generator output voltage of 14V.
