Plug-in hybrid cars are far more fuel effective than internal combustion engine cars, but it tries out that the technique the cars energy management systems stabilities the energy load between the battery and gas engine isn’t always the most efficient.
Researchers at the University of California, Riverside looked to nature evolutionary systems for inspiration, mostly how birds flock and fly in formation in order to recover their energy efficiency, and came up with a new technology that progresses that balance and reduces fuel consumption of plug-in hybrids by 30%.
The university says that but not all plug-in hybrids work the same, many of them have energy management systems that first place the car in all-electric mode until the battery is sapped and then switch into hybrid mode. Research has initiate that this split is not the most efficient technique to balance the two power sources in the plug-in hybrid, but that combination the two power modes and using the battery through a car trip minimizes fuel consumption.
This way of handling the energy sources is more difficult though because it requires to car to stability the energy in the most effectual way depending on what the driving conditions and traffic are like throughout the route. This needs a lot of real-time information processing.
To complete this, researchers Xuewei Qi, a postdoctoral researcher at the Center for Environmental Research and Technology, and Matthew Barth, CE-CERT director and a instructor of electrical and computer engineering at UCR, mutual information imminent from vehicle connectivity with cellular networks and crowdsourcing path with an evolutionary algorithm that mathematically illustrates energy good behavior in nature like birds flocking and insect swarming.
“By mathematically modeling the energy valid processes that occur in nature, scientists have shaped algorithms that can be used to resolve optimization problems in engineering,” Qi claimed. “We shared this approach with connected vehicle technology to accomplish energy savings of more than 30 percent.”
Output of the car can be heightened even more by having the system study from what precious fuel consumption in the car’s previous trips. Associated vehicles could then share the knowledge with other vehicles on the same network. This method would mean that the EMS in each car was continually improving and continually result new ways to reduce fuel consumption and emissions.
