Abstract: An exemplary thermal management system includes, among other things, a heater loop, a battery loop, a radiator loop, and a power electronics loop operating within a glycol system. A first valve is in fluid communication with one or more of the heater loop, the battery loop, the radiator loop, and the power electronics loop. A second valve is in fluid communication with one or more of the heater loop, the battery loop, the radiator loop, and the power electronics loop. A refrigerant system cooperates with the glycol system under at least one operational condition to actively chill power electronics in the power electronics loop and a battery in the battery loop while actively heating a cabin area.

Abstract: A lithium-ion battery cell is preconditioned using an initial, one-time process of cell formation at an elevated temperature, or after cell formation, charge/discharge cycling for a predetermined number of cycles within a specified period of time at an elevated temperature prior to being placed in service. The process may be performed as part of manufacturing during cell formation after electrolyte filling and pre-charging. Alternatively, the pre-conditioning process may be performed after assembly of finished cells within a multi-cell battery, either before or after installation of the battery in a product, but before the battery is subjected to harsh conditions, such as fast charging and/or discharging at low temperature. An electrified vehicle may include an electric machine powered by a multi-cell lithium-ion battery preconditioned according to the initial, one-time process.

Abstract: An electric drive system and a heating method. The electric drive system includes an inverter circuit, a direct current-direct current conversion circuit, and a controller. An input end of the inverter circuit is connected to an input end of the electric drive system, and an output end of the inverter circuit is connected to three-phase motor windings of an electric excitation synchronous motor. An input end of the direct current-direct current conversion circuit is connected to the input end of the electric drive system, and an output end of the direct current-direct current conversion circuit is connected to an excitation winding of the electric excitation synchronous motor. In this solution, a heating apparatus does not need to be disposed when the power battery pack is heated, thereby reducing costs and saving space.

Abstract: A method to transport a battery for an unmanned aerial vehicle using a battery transport box, the box having a box body shell and an upper cover. The unmanned aerial vehicle battery transport box further having a heat dissipating device and a heating device. When the temperature in the box body is lower than the lower limit of the set temperature range, the heating device heats the box body. When the temperature in the box body is higher than the upper limit of the set temperature range, the heat dissipating device dissipates heat of the box body. The temperature in the box body is adjusted by the heating device and the heat dissipating device.

Abstract: To adsorb an adsorbate rapidly on a heat storage material with good energy efficiency. A chemical heat storage device includes an adsorbate, a heat storage material, and a sprayer. The adsorbate is in a liquid state at normal temperature. The heat storage material releases heat of adsorption in response to adsorption of the adsorbate on the heat storage material and stores the heat of adsorption in response to desorption of the adsorbate from the heat storage material. The sprayer sprays the adsorbate on the heat storage material in a heat release period of causing the heat storage material to release the heat of adsorption. With the above-described configuration, it is possible to increase a speed of diffusion of the adsorbate in the heat storage material through spraying of the adsorbate on the heat storage material.
