The Car Will Surely Start With the Mercedes Benz Relay

By: Kimberly Baker

The first thing that a driver worries about after getting into the car is if the car will start once he turns the key into the ignition. This is crucial because this moment will determine the total function of the car engine---for how can you determine its performance if it would not run in the first place? But if the car is hooked up with the Mercedes Benz Relay, then it would be next to impossible for the car not to start. Because the name Mercedes Benz speaks of quality and efficiency, it is trusted to carry out its tasks with perfection.

The Mercedes Benz Relay is an electromagnetic switch. When power or ground is applied to a coil, the relay clicks on or off. The result is that a power wire to a function is either closed (connected) or opened (disconnected). When the line is connected, the function is turned on and works. When the line is disconnected, the function is turned off and will not work. A relay can be used on alarm systems to disable the starter, to flash the parking lights, and more. It is responsible for starting the car, along with the other main components of the engine. Meanwhile, the relay serves a lot of other functions too because of its electric nature. One of them is Car Conversion.

A lot of motorists have preferred to use Electric Cars instead of the gasoline-powered ones because it is less costly, and less of a pollutant. A typical conversion uses a DC controller and a DC motor. The person doing the conversion decides what voltage the system will run at typically anything between 96 volts and 192 volts. The voltage decision controls how many batteries the car will need, and what sort of motor and controller the car will use. Usually, the person doing the conversion has a "donor vehicle" that will act as the platform for the conversion. Almost always, the donor vehicle is a normal gasoline-powered car that gets converted to electric.

Once the decisions about the motor, controller and batteries are made, the conversion can start. One will have to remove the engine, gas tank, exhaust system, clutch and perhaps the radiator from the donor vehicle. Then, attach an adapter plate to the transmission and mount the motor. The motor normally requires custom mounting brackets. Usually, the electric motor needs a reduction gear for maximum efficiency. The easiest way to create the gear reduction is to pin the existing manual transmission in first or second gear. It would save weight to create a custom reduction gear, but normally it is too expensive. Next, the person must mount the controller. Find space for, and build brackets to safely hold all the batteries. Install the batteries and wire them to the controller with gauge welding cable.

Install a DC-to-DC converter to power the accessory battery. Install a large (also known as a contactor) that can connect and disconnect the car's battery pack to and from the controller. This relay is how you turn the car "on" when you want to drive it. You need a relay that can carry hundreds of amps and that can break 96 to 300 volts DC without holding an arc. Rewire the ignition switch so that it can turn on all the new equipment, including the Mercedes Benz Relay. Mercedes Benz has proven its expertise and utility in the continuous evolution of the automobile, and they will not be stopping any time soon.
