The savings mechanisms are demand charges (utility and grid) and time-of-day rates, which are available to non-residential customers. With available state and utility incentives, we are able to see 3-7 year paybacks across the U.S. 3D Histogram of active thermal storage projects Our biggest markets are K12, hospitals, universities, and office, and the opportunity is essentially limitless. Over 1 GW (4,000+ projects) of CALMAC® thermal batteries installed worldwide 9 #1 Challenge is Awareness • Almost no one understands commercial demand charges. • Even fewer understand Grid demand charges (PJM, ISO-NE, NYISO, etc.). • Plurality of deregulated market customers are on fixed priced contracts that cost more, year after year, than default option “Everyday customers” like schools, hospitals and universities are unsophisticated in terms of energy – rate and tariff design is opaque, and utility reps are typically insufficiently trained to provide them with the necessary clarity. There is no unbiased resource they can turn Trane marketing piece from August 2018 to for help. 10 Utility Bills Cloud Understanding Some states require no itemization at all • “here’s your bill, pay up” Typical 3rd Party Supply Bill • “blended” electric rate of 7.5 cents/kWh Default Service Customer • No mention of PJM’s Capacity or NITS • Itemization, but no explanation charges, which are peak-related 11 Thought Experiment Cable bill vs. Grocery Bill • One you receive up front; the other comes in the mail two weeks after the fact • One is itemized in a way that you can easily follow; the other is littered with unexplained fees and surcharges • One is naturally easy for the human mind to grasp; the other is based on abstract telecommunications concepts and is determined by a legal proceeding between the FCC, your public utility commission, and the providers Which one do you actually understand? 12 Summary These are exciting times for all of us in the energy storage industry • Thermal storage business is growing steadily, thanks to new incentives and new appreciation • The technology has been compelling for a long time • The greatest challenge by far is awareness of how C&I customers are charged for their power 13 © 2020 Trane.

The design of an innovative yet well-functioning BTMS requires strict supervision, quality audit and continuous improvement of the whole process. It must address all the current quality and safety (Q&S) standards. In this review article, an effective battery thermal management is sought considering the existing battery Q&S standards and scientific literature. The article contains a broad overview of the current existing standards and literature on a generic compliant BTMS. The aim is to assist in the design of a novel compatible BTMS. Additionally, the article delivers a set of recommendations to make an effective BTMS. Keywords: battery thermal management system (BTMS); battery management systems (BMSs); thermal imaging; calorimetry; isothermal calorimeter; batteries; quality and safety (Q&S) standards; Li-ion batteries 1. Introduction The main barriers to the deployment of large fleets of vehicles on public roads equipped with lithium-ion batteries continue to be safety, costs related to cycle and calendar life, and performance. These challenges are coupled with thermal effects in the battery, including capacity/power fade, thermal runaway, electrical imbalance among multiple cells in a battery pack, and low-temperature performance [1,2].

  • Analysis of Heat-Spreading Thermal Management Solutions For
    ANALYSIS OF HEAT-SPREADING THERMAL MANAGEMENT SOLUTIONS FOR LITHIUM-ION BATTERIES THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Hussam Jihad Khasawneh Graduate Program in Mechanical Engineering The Ohio State University 2011 Master's Examination Committee: Marcello Canova, Advisor Yann Guezennec, Co-advisor Copyright by Hussam Jihad Khasawneh 2011 Abstract Electrical storage technologies (i.e., batteries) play a ubiquitous role in all facets of modern technologies for applications ranging from very small to very large scale, both stationary and mobile. In the past decade, Li-ion batteries are quickly emerging as the preferred electrical energy storage technology due to the intrinsic power and energy storage density compared to older battery chemistries. All electrochemical batteries are strongly linked to their thermal state: on one hand, their electrical characteristics are strongly dependent on temperature and, on the other hand, their thermal state is a result of both their environmental temperature, but also their electrical usage due to internal heat generation. Furthermore, their life (and potentially safety) is also strongly affected by their thermal state. Li-ion batteries, due to their high electrical power capability and density tend to be used aggressively in many applications, rendering the thermal issues more acute. Finally, Li-ion battery packs (like all packs) are made of many cells interconnected in various series/parallel arrangements in tightly confined spaces. Hence, thermal management solutions need to be implemented for two primary reasons: rejecting the heat generated inside the pack to the environment to avoid high (or unsafe) temperatures leading to premature (or catastrophic) failure and providing a good thermal uniformity among all the cells so that their electrical performance (and aging) in well ii matched in a pack.

ABSTRACT Abundant use of fossil fuels to meet ever increasing global energy requirements has put question marks upon the sustainable future of human beings because of the environmental concerns. Research and development of new and renewable energy resources is mainly focused by researchers in recent decades. Solar Thermal Energy is one of the major technologies esteemed to replace the fossil fuels. Purpose of this research is to design and fabricate solar thermal battery to utilize natural solar resource for generation of electricity instead of fossil fuel. This paper proposes the design and fabrication of Solar Thermal Battery. To achieve the desired objective, the work is divided into two parts. In first part, all the materials regarding Solar Thermal Battery i.e. stainless steel, molten salts, insulation materials, suction creation, temperature and pressure gauges have been analyzed and characterized in detail. Heat storage materials have been experimentally characterized for insulation stability. Sodium Nitrate (NaNO3) and Potassium Nitrate (KNO3) are described in context of efficiency. In second part, designing and fabrication of Solar Thermal Battery has been discussed in detail. In designing process, stainless steel sheets are rolled and welded through organ welding plant to create vacuum suction.
