Chevrolet Cruze Ushers in RVC; Aims at Better Fuel Economy

March 29, 2011 / No Comments

Chevrolet has deployed a new technology in their Cruze, and is believed to be successfully saving fuel. The patented technology from General Motors, known as Regulated Voltage Control or RVC, is aimed at enhancing the fuel economy of the vehicle.

According to Doug Dickson, an electrical engineering specialist with the GM Global Energy Center, the technology will help improve fuel economy on the Cruze by up to 1.5 percent. RVC enables more than eight additional miles of range on every tank of fuel – that sounds too good, doesn’t it?

So how does the RVC work? GM explains it this way: The power that runs from the alternator to the battery of the vehicle is reduced from 14 volts to 12.8 volts under normal driving conditions with the RVC. The alternator converges on the power on the vehicle’s electrical loads that in turn avoids charging the battery with current that is not required by it.

By reducing the voltage to the battery, the demand on the alternator is also snipped. That helps reduce the alternator’s pull on the engine too, allowing the engine to run more efficiently.  Thus the fuel economy is made better with the enhancement in the working of the engine.

When the battery is fully charged, RVC supplies power to handle the load created by gadgets in the vehicle. That comes in handy as it electrical demands on the alternator and the engine are further cut down.

When the battery charge is low, the alternator supplies the needed voltage to recharge the battery. The battery, thus, remains fully charged through automatic recharging.
