The actual voltage, matching the car battery's voltage, will be approximately 12.5 volts when dormant (less in cold conditions), approximately 14.5 volts when the engine and the alternator/generator are operating (more when cold), and may briefly drop as low as 5–6 volts during engine start due to the high temporary battery current usage.

An ECU from a Geo Storm. An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
The earliest electronic systems available as factory installations were vacuum tube car radios, starting in the early 1930s.The development of semiconductors after World War II greatly expanded the use of electronics in automobiles, with solid-state diodes making the automotive alternator the standard after about 1960, and the first transistorized ignition systems appearing in 1963.
Hacking into your computer and phone was bad enough, but this take the fear for cyber attacks to a whole new level. Hackers can now take over your car's controls, while you are driving.
After 25 years on the market, most people know what a hybrid car is—even if the only one they can name is the Toyota Prius.And battery-electric vehicles are simple: plug in them to charge the ...
Soft bricked devices can usually be fixed relatively easily; for example, a soft bricked iOS device may display a screen instructing the user to plug it into a computer to perform an operating system recovery using iTunes computer software. [3]
In-car Internet refers to Internet service provided in a car. Internet access can be provided by tethering a mobile phone , with a mobile hotspot , or with any satellite based connections, whether portable or built into the car.
A challenge to installing a computer in a car is the power supply. Energy is supplied as a nominal 12 VDC in cars or 24 VDC in some trucks. The voltage varies according to whether the engine is on or off since the battery generally delivers 12V, while the generator supplies more. There can be peaks, and at ignition time the supply current drops.
