A simulation system of the present disclosure for performing an experiment on a battery pack including a plurality of battery cells by using at least one experimental device includes: an IoT device that receives input and output of at least one experimental device, and pre-processes the input and the output to generate input data and output data; an edge computing device for predicting information for predicting a capacity degradation value of a plurality of battery cells by using an equivalent circuit model module and a thermal model module based on data received among the input data and the output data; and a server that receives the predicted information from the edge computing device, predicts a capacity degradation value of a plurality of battery cells by using an aging model module, and predicts a defect rate based on the predicted capacity degradation values. The data size of the input data and output data transmitted from the IoT device to the edge computing device may be smaller than a predetermined data size.

A cooling circuit for a vehicle includes a single cooler, a refrigeration machine, a first heat-generating device, a second heat-generating device, a coolant pump arrangement configured to pump a coolant, a valve arrangement, and an electronic control module. The first heat-generating device requires the coolant at a first coolant temperature level. The second het-generating device requires the coolant at a second coolant temperature level. The valve arrangement is configured to supply the coolant from the first and second heat-generating devices to the refrigeration machine and/or to the single cooler. The electronic control module is designed to control a temperature of the coolant at coolant inlets of the first and second heat-generating devices by varying flow rates of the coolant through the refrigeration machine and/or the single cooler.

A vehicle comprises a battery, a temperature adjustment unit, an inlet, a relay unit, a relay unit, a relay unit, and an ECU. When a power charging station is connected to the inlet, the ECU controls the relay unit to assume a closed position to perform external charging to charge the battery by the power charging station. When the ECU drives the temperature adjustment unit during the external charging and a component on a charging path at an electrical path located between a branch point and a branch point is higher in temperature than a threshold temperature, the ECU controls the relay unit to assume an open position and the relay unit to assume a closed position.

There is disclosed in one example an apparatus, including: a hardware platform including a processor and a memory; and instructions encoded within the memory to instruct the processor to: receive stored performance data for an aircraft battery, the stored performance data including data that correlate power density to temperature and remaining charge; simulate a planned flight for an aircraft, including predicting a plurality of temperature and remaining charge values; and direct operation of a heat exchange apparatus to precondition the battery to a selected temperature before the planned flight.

An electric vehicle includes a wheel, an electric motor to drive the wheel, a battery to supply electric power to the electric motor, the battery including battery cells and a battery casing to house the battery cells, an onboard charger to charge the battery, the onboard charger being opposed to and spaced apart from an outer surface of the battery casing so that an air flow path exists between the onboard charger and the outer surface of the battery casing, and a cooling fan to generate a flow of air passing through the air flow path between the onboard charger and the battery casing.

A vehicle includes a vehicle cooling system for cooling a cabin and a battery system, each having a respective target operating range. The cooling system is configured to select among a cabin-only mode, battery-only mode, or a hybrid cooling mode for cooling the cabin and the battery system. In the hybrid mode, the system determines a desired pressure at an inlet of a compressor corresponding to a suction pressure of the compressor, to avoid cooling interruptions. The system generates a control signal based on the desired suction pressure, and applies the control signal to the compressor. Generating the control signal may include generating a feedforward signal the desired suction pressure, generating a feedback signal based on the suction pressure, or a combination thereof. For example, the use of hybrid mode based on suction pressure allows smoother response to targets with reduced delays in response in meeting the cooling demands.
