Manitoba researchers are monitoring power usage of plug-in hybrid electric vehicles.

Researchers at the University of Manitoba are working to determine how the increased use of electric-powered hybrid vehicles will affect the province's power supply.

U of M and Manitoba Hydro researchers are monitoring test-drive results of four older-model Toyota Priuses that have been converted to plug-in hybrid electric vehicles.

Concurrent with that research, Manitoba Science and Technology Minister Jim Rondeau said a Manitoba company is developing the use of wireless technology that can limit the power used for charging electric car batteries if peak hydroelectric usage across the province has been reached.

The wireless technology also will track a battery's usage, so the owner pays for its charging, regardless of where the car is plugged-in — at work, for example, a public parking stall, or the next-door neighbour's outdoor electrical outlet.
