  • Patent number: 10953726
    Abstract: A method for managing thermal energy of a vehicle having a battery and an electric propulsion system is provided. The system monitors a current battery temperature, after the vehicle is connected to an outside power source at a plug time, and determines an outside air temperature. The system predicts a cabin heating temperature for a subsequent drive cycle. The subsequent drive cycle occurs when the vehicle is no longer connected to the outside power source. If the predicted cabin heating temperature is greater than the outside air temperature, the system heats the battery to a thermal storage temperature that is greater than a target operating temperature of the battery. Therefore, thermal energy is stored within the battery, and may be transferred to heat the cabin.

  • Patent number: 10890355
    Abstract: A heat pump apparatus includes a use-side heat exchanger that causes heat exchange to be performed between a heat medium flowing from a heat-storage heat exchanger and a heat usage medium, and a flow-passage switching device that switches a flow passage for the heat medium to a first flow passage that circulates through a heat-reception-side heat exchanger and the heat-storage heat exchanger without extends through the use-side heat exchanger or a second flow passage that circulates through the heat-reception-side heat exchanger and the heat-storage heat exchanger via the use-side heat exchanger. Even when the temperature of the heat storage medium rises, heat received from a heat source can be stored in the heat storage medium by a heat pump, while a decrease of the efficiency of the heat pump can be reduced.

  • Patent number: 10859262
    Abstract: A toxic waste incinerator is capable of enhanced combustion of hazardous waste (oil contaminated sand, human waste, garbage, etc.) utilizing immersed non-combustible and thermally conductive objects for increasing heat feedback from the flames to the unburned fuel, while air inlets are used to optimize the air entrainment rate to enhance the burning efficiency. The burning rate of a fluidic mass such as a sand-oil mixture is enhanced using immersed conductive objects (copper rods) which enable rapid heat-up of the flame exposed to the upper surface of the rod and transmits heat back into the sand. Consequent conduction of heat to the porous media through the lower portion of the immersed rod significantly increases vaporization and therefore the burning rate. Incineration may be performed on a transient, exigent basis as with hazardous waste and oil spills, or as part of a permanent fixture for receiving an ongoing waste stream.
