“…To reduce the number of iterations needed to perform the mesh, only 4 charge temperatures have been used, 40 • C, 70 • C, 100 • C and 140 • C. The upper limits for the search are based on previous studies from literature. The mass and charge temperature are in line with the largest values seen in literature [22], [29]. The maximum power was chosen to exceed 16.5kW, which was the maximum heating capacity of the PTC and heat pump used in this model.…”

“…Promising materials in this area include paraffin wax, non paraffin waxes (with paraffin like properties), fatty acids and super saturated salt water solutions. In 2016 LaClair proposed the use of a 2.7kWh thermal battery weighing 33kg with a volume of 31L to cover the entire heating load for a 23 minute commute twice in a day (46 minutes total) [22]. The thermal battery had an operating temperature range of 60 − 120 • C, where 60 • C was deemed the minimum temperature useful for cabin heating.…”

“…In the example above, the minimum temperature that the thermal battery was deemed useful was 60 • C. This is because the anything less than 60 • C is not sufficiently hot to warm the air in the heater core [22]. However, the thermal battery is clearly still warm and more thermal energy can be extracted, which is where a heat pump becomes useful.…”

“…The mass was then chosen so that the stored energy was equivalent to 1.39kWh, which just exceeds the energy used by the PTC heater during a 20 minute warm up period. The thermal power was chosen to be in-line with the maximum value seen in literature [22].…”

Abstract:Previous research has focused on the use of heat pumps in electric vehicles, with the focus on recuperating heat from, normally, ambient and one thermal source on the vehicle. Here 5 potential thermal sources on a vehicle have been identified and thorough testing on the benefit of each source has been performed. The results presented suggest the motor, a thermal storage device, and cabin exhaust extraction should be used >80% of the time according to the scenarios tested, while battery heating and transmission heat extraction should be used subject to conditions on the ambient temperature and drive cycle.

Phase change materials (PCMs) can enhance the performance of energy systems by time shifting or reducing peak thermal loads. The effectiveness of a PCM is defined by its energy and power density-the total available storage capacity (kWh m −3 ) and how fast it can be accessed (kW m −3 ). These are influenced by both material properties as well as geometry of the energy systems; however, prior efforts have primarily focused on improving material properties, namely, maximizing latent heat of fusion and increasing thermal conductivity. The latter is often at the expense of the former. Advanced manufacturing techniques hold tremendous potential to enable co-optimization of material properties and device geometry, while potentially reducing material waste and manufacturing time. There is an emerging body of research focused on additive manufacturing of PCM composites and devices for thermal energy storage (TES) and thermal management. In this article, the fundamentals and applications of PCMs are reviewed and recent additive manufacturing advances in latent heat TES for both the PCM composite and associated heat exchanger are discussed. A forward-looking perspective on the future and potential of PCM additive manufacturing for TES and thermal management is provided.
