Reference number : GC-2017-Q1-01606, amendment number : , agreement type : G, recipient legal name : dunford, william (The University of British Columbia), recipient country : CA, recipient province : nan, recipient city : British Columbia|Colombie-Britannique, recipient postal code : nan, program name english : Discovery Grants Program - Individual, program name french : Programme de subventions à la découverte - individuelles, program purpose english : Previous work on system level energy distribution will be continued, with a particular focus on DC 
systems in domestic and vehicle applications. Much expertise in the modelling of batteries and 
photovoltaic systems has been accumulated and explicit application to the electric vehicle and 
domestic area will be pursued. In particular, some work on how DC should be distributed in a 
house has been published and this will be taken further. Safety is a particular interest in terms of 
how designs will fail in a non hazardous manner. Designing a switch which does not arc is of little 
value if the eventual failure mode is that it will burn the house down. 
A related area is the design of distribution systems in electric vehicles of all types. Of particular 
interest is the interface between the vehicle and the rest of the world. In some cases this involves 
wiring in a building. In other cases it is a powering or charging system at the road level. There has 
been much discussion of wireless systems, but I believe these to be of limited practical interest. 
Improved methods of contact charging methods, such as through the use of robot plugging units, 
promise more compact and efficient solutions. An extension of the trolley bus system has been used 
for large commercial vehicles and this promises to provide a quick way of removing emissions from 
city centres, particularly where suitable transportation infrastructure already exists. 
Establishing codes and standards and standards for DC distribution will a general goal. It is the lack 
of these which has hampered the adoption of DC for many years. The advantages of using DC in a 
naturally DC environment of photovoltaics and batteries are clear. The proposed work will focus on 
getting beyond the experimental stage., program purpose french : Previous work on system level energy distribution will be continued, with a particular focus on DC
