Abstract:
A vehicle includes a traction battery subject to alternating cycling and storage modes and a controller. The controller is programmed to calculate an accumulated degradation for the traction battery based on a degradation profile for the traction battery. The degradation profile defines degradation accumulated over time and may differ based on the mode and temperature. The initial degradation value includes the accumulated degradation for the present mode and at least a portion of the accumulated degradation for the other mode. Degradation is then accumulated according to the degradation profile starting from the initial degradation value. The amount of accumulated degradation from the other mode that is included may vary based on the mode and the accumulated degradation.

Abstract:
A system and method for management of an energy storage system for a vehicle is disclosed. The energy storage system may comprise a battery system for a vehicle such as an electric vehicle or hybrid-electric vehicle. Vehicles may be in a group or fleet. The management system may be configured to use data and information available from data sources over a network or by instrumentation/sensors for vehicle systems. Data and information could be used in a system to manage the configuration and operation of the energy storage system and components, manage/control inventory and use/life-cycle of components, and/or aggregated/analyzed in analytics function for systems and components. Predictive control of the battery system may be implemented through a management system using data sources external to the vehicle. Inventive concepts and features of the systems and methods are indicated in the specification and FIGURES.
Abstract:
A system and method for operating a fuel-cell system, which is attached to at least one further component via a cooling and/or lubricating circuit. A water-based, oil-free coolant and lubricant is used, and a flushing procedure for the fuel cell is initiated when a contamination of the fuel cell by the water-based, oil-free coolant and lubricant is detected.
Abstract:
There is provided an air-conditioning apparatus including an auxiliary power supply that, when a voltage from an overhead line extending over sections powered by different power sources is stepped down with a transformer, converts the voltage into a low-voltage DC voltage and that, when a voltage from the overhead line is a DC voltage, is directly fed with the voltage and converts it into the low-voltage DC voltage that is the same as the converted DC voltage, and further including an inverter device that converts the DC voltage from the auxiliary power supply into an AC voltage and that supplies the AC voltage to a drive unit of a refrigeration cycle apparatus.
Abstract:
A DC-to-DC converter may be disposed in a vehicle for converting a high voltage from a power source to a low voltage. The DC-to-DC converter may include a primary converter, a secondary converter, and a DC-to-DC module. The DC-to-DC module may control the operation of the secondary converter based on a set-point threshold and a power output of the primary converter, where the set-point threshold may be variably set.
Abstract:
The purpose of the present invention is to improve the operation efficiency of an internal combustion engine while supplying a required drive force for an electric motor. A power generation control device determines the appropriateness of power generation by a power generator in accordance with the state of a storage battery, and when allowing power generation, sets the amount of power generation equivalent to an output required for cruising in accordance with a travelling state, while setting an additional amount of power generation in accordance with the amount of power required depending on a vehicle state and the traveling state.
Abstract:
A warm-up apparatus for a vehicle including a system which charges a battery by using an external power supply is provided. The warm-up apparatus includes a heater for warming up, a current detector, a voltage detector and a resistance changer. The heater is mounted in the vehicle and produces heat by receiving electric power from the external power supply. The current detector detects an allowable current value of the external power supply. The voltage detector detects an output voltage value of the external power supply. The resistance changer changes an electric resistance value of the heater based on the allowable current value detected by the current detector and the output voltage value detected by the voltage detector.
