The heat energy maintains the engine temperature for efficient combustion as a good aspect, but the amount of heat generation is excessive and eventually breaks the engine components unless advanced cooling system technologies are supported such as high-capacity radiators, elaborated water jackets, high-flow rate coolant pumps, etc. The excessive heat dissipation plays a key role on a poor fuel economy, but reclamation of the heat energy has not been a main focus of vehicle design. This work is first to propose a cross-layer, system-level solution to enhance thermoelectric generator (TEG) array efficiency introducing online reconfiguration of TEG modules. The proposed method is useful to any sort of TEG array to reclaim wasted heat energy because cooling and exhaust systems generally have different inlet and outlet temperatures. In this paper, we deploy the proposed method to vehicle radiator heat energy harvesting, which does not affect the vehicle performance while exhaust heat energy harvesting may disturb the combustion and emission control integrity. We introduce a novel TEG reconfiguration and maximize the TEG array output in spite of dynamic change of the coolant flow rate and temperature, which results in a huge variation in the coolant temperature distribution of inside the radiator. The proposed method enables all the TEG modules to run at or close to their maximum power points (MPP) under dynamically changing vehicle operating conditions. Experimental results show up to a 34% enhancement compared with a fixed array structure, which is a common practice.","PeriodicalId":385714,"journal":{"name":"2017 IEEE/ACM International Symposium on Low Power Electronics and Design (ISLPED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116633612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing governors determine system configuration only based on low-level information such as CPU load without any input about application-level behaviors. In particular, there exists no communication from mobile apps to energy managers. We find that information about app usage scenarios (e.g., gaming, video chatting) can usually help energy manager perform a better job and achieve more energy savings. Although app-level energy optimizations have been proposed, they generally focus on single usage scenarios and do not address optimization across multiple scenarios. In this paper, we propose SceneMan, an energy optimization framework for mobile apps based on usage scenario notification. SceneMan has three components: an API, a scenario notifier, and an energy manager. The key idea is to make energy managers aware of app-level scenarios. At runtime, apps notify the energy manager about their usage scenarios with provided APIs used by developers. The energy manager then takes appropriate actions to minimize energy consumption of the running scenario while meeting performance requirements. Energy optimization across scenarios can thus be easily achieved. The framework requires little extra programming effort and can help apps achieve better energy efficiency in a transparent way. We implement our system on a Nexus 6 smartphone and test it with 13 real-world apps under 2 usage scenarios, namely, gaming and video chatting. We achieve up to 33.2% energy savings with a worst-case performance loss of 5.1%.","PeriodicalId":385714,"journal":{"name":"2017 IEEE/ACM International Symposium on Low Power Electronics and Design (ISLPED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125015560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
