Design Automation of Things: Power Consumption Characterization, Modeling and Estimation of Electric Vehicles

Title: Design Automation of Things: Power Consumption Characterization, Modeling and Estimation of Electric Vehicles

Speaker:  Professor Naehyuck Chang

Date/Time:  Tuesday, February 10, 2015, 2:00pm to 3:00pm

Location:  Harut Barsamian Colloquia Room (EH 2430)

Host: Nikil Dutt

Abstract:

Rapid electric vehicle (EV) penetration gives a threatening challenge in electric energy generation. An 1,814 kg curb weight full electric vehicle driving 18,129 km/year consumes electricity energy equivalent to 74% of the total residential electricity use per person in the US. This implies that 27% more nationwide electricity generation is needed when 70% of passenger vehicles are replaced with EVs.

This talk introduces the first step toward systematic EV design-time and runtime optimization. We develop instantaneous power consumption modeling of an EV by the curb weights, speed, acceleration, road slope, passenger and cargo weights, motor capacity, and so on, as a battery discharge model. The model also considers the onboard charger, regenerative braking and so on, as a battery charge model. To insure model fidelity, we fabricate a lightweight custom EV, perform extensive measurement, and derive model coefficients using multivariable regression analysis. We estimate the EV instantaneous power consumption of a given speed and route profiles and verify the estimation fidelity with a real test run data. This talk will also cover the on-going project for the next version electric vehicle with four-wheel drive capability.

 

 
Connected Context Computing for Smart IoT

Speaker: Jane Yung-jen Hsu

Title: Connected Context Computing for Smart IoT

Date: Tuesday, February 10, 2015

Time: 3:30pm

Location: Harut Barsamian Colloquia Room (Engineering Hall 2430)

Host: Professor Kwei-Jay Lin

Abstract:

We are witnessing the explosion of connected devices, or the so-called Internet of Things, in our everyday lives. This new trend has created new opportunities to monitor human activities and to configure environments for comfort, security, or energy savings. In the US, buildings account for roughly 40% of total energy usage, with major contributions from the cooling demands. While most people have no intention of wasting energy, they are often unaware of the energy footprint of their daily routines. Activity recognition is a key capability for a smart environment to offer timely services and intelligent interactions with people.

In this talk, I will introduce connected context computing and its significance in enabling our vision of smart IoT. In particular, I will share our experience on monitoring the Computer Science building on NTU campus to improve its air conditioning and space utilization. First, an agent-based HVAC service is designed to analyze cooling demands and wastes. Second, experiments on SweetFeedback are conducted to encourage energy-saving behaviors. Third, crowd sourcing cyber-physical agents are deployed to acquire status labels for activity recognition from people situated in the environment. Â Our experiments showed that context computing, predictive analytics, and proactive control are the fundamental building blocks for a smart IoT framework that can SCALE (Sense, Communicate, Analyze, Learn, Expect and Effect).
