Abstract: An integrated power supply includes a first low voltage DC-DC converter (LDC) that converts supply power to a first output voltage and provides the first output voltage to a first auxiliary battery and a first electric load connected to each other in parallel; a second LDC that converts the supply power to a second output voltage and provides the first output voltage to a second auxiliary battery and a second electric load connected to each other in parallel; and an integrated controller that controls the first LDC and the second LDC to change output voltages of the first LDC and the second LDC. The first auxiliary battery and the second auxiliary battery are connected in series, and when the first LDC fails, the second LDC outputs a second increase output voltage that is higher than the second output voltage under control of the integrated controller.

Abstract: The invention relates to an optimal allocation method for stored energy coordinating electric vehicles (EVs) to participate in auxiliary service market (ASM), including the following steps: 1. Predict the reported capacity of daily 96 points for EVs to participate in the ASM by least square support vector machine (LSSVM). 2. Fit the daily total load distribution of EVs. 3. Determine the error distribution between the reported capacity and the actual response capacity, and simulate the total daily load capacity of EVs in the future with Monte Carlo method. 4.

Abstract: An in-vehicle control system is equipped in a vehicle, and includes an image drawer, a reproduction controller and a voltage detector. The image drawer draws a pictorial measuring instrument as an image representing a measuring instrument related to travelling of the vehicle. The vehicle includes an audiovisual information output device and a reproduction signal generator. The audiovisual information output device outputs audiovisual information for an occupant in the vehicle. The reproduction signal generator generates a reproduction signal for causing the audiovisual information output device to output the audiovisual information. The reproduction controller reproduces the audiovisual information, stops reproduction of the audiovisual information, resumes the reproduction of the audiovisual information from a stop position of the reproduction of the audiovisual information, and transmits an instruction to the reproduction signal generator for generating the reproduction signal. The voltage detector detects a value of a voltage of a battery equipped in the vehicle.
