DENSO and Nagoya University Jointly Develop In-vehicle Battery-based Energy
Management System 
Efficiently controls charging and discharging of in-vehicle batteries based on
forecasting models of household electricity demand and vehicle use 
Kariya, Japan, Sept 27, 2013 - (JCN Newswire) -  Global automotive supplier
DENSO and Nagoya University have developed an in-vehicle battery-based energy
management system (EMS), which uses forecasting models of household electricity
demand and vehicle use to reduce electricity costs. The two organizations will
start to evaluate the performance of the system in October this year under the
Toyota City Low-carbon Society Verification Project, one of the Next-Generation
Energy and Social System Demonstration Projects in Japan led by Japan's
Ministry of Economy, Trade and Industry (METI). 
The EMS coordinates with batteries used in electric and plug-in hybrid
vehicles to use their stored electricity to help keep down electricity bills.
The system measures power consumption, the amount of power generated by solar
panels, vehicle use, and other household characteristics to construct models
for forecasting household electricity demand and vehicle use. Based on these
estimates, the system controls the charging and discharging of the in-vehicle
battery in real time, reducing the amount of power purchased when the rates are
high while increasing it when the rates are low to save money on electricity. 
Batteries used in electric and plug-in hybrid vehicles are frequently
connected (when the vehicle is parked) and disconnected (when the vehicle is
used) from the EMS. To use these batteries effectively, there are issues to be
resolved, including accurately predicting the times of the day when the vehicle
is parked and optimally controlling battery charging and discharging depending
on the household electric power demand. To address these challenges, DENSO and
Nagoya University have been working together since 2010 to develop this EMS by
combining DENSO's vehicle-to-home (V2H) technologies to supply power from
in-vehicle batteries to home devices and Nagoya University's modeling,
forecasting, and optimization technologies. 
In October 2012, the development of this system was chosen as a new focus for
FY2012 under the Strategic Basic Research Project (CREST), a basic research
program conducted by the Japan Science and Technology Agency. 
Based on the results of the field test that will be held from October 2013 to
March 2014, DENSO and Nagoya University will consider commercializing this
