New Heating System Development Working with Waste Heat for Electric Vehicles
Open accessAbstract
Researches carried about electric vehicles are focused on extending life of the battery today. Development of higher-range batteries is as essential as efficient use of current battery energy technology. EPT System, that has average efficiency of 85%, produces waste heat up to 15% of its nominal power. The current heat pump systems, which use the waste heat, are very expensive and have complicated structures. In addition, the energy is consumed about 50% of heat transfer with this way. With the newly developed and patent applied system, the average temperature of the waste heat of the engine is raised to the temperature of engine efficiently operating In addition, the energy could be used for heating purposes without additional energy consumption. Newly developed heating system can heat with high efficiency using heat pump and stored electrical energy from heat through braking energy without any extra energy consumption.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
In BEVs, cabin heating energy demand must be supplied by the battery because less waste heat is available from the powertrain than in ICEVs, which adds to energy consumption and reduces range.
“Since electric powertrains have a higher efficiency than conventional ones, BEVs have less waste heat available for cabin heating than ICEVs.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
