Abstract: A battery module for an electrified vehicle includes a first battery cell having a housing, a cathode, a positive end lead, an anode, a negative end lead, an isolator and a fuse. The cathode and anode can be disposed in the housing. The positive end lead can be arranged on the housing and electrically connected to the cathode. The negative end lead can be arranged on the housing. The isolator can be disposed between the housing and the negative end lead. The isolator can inhibit voltage from passing between the housing and the anode. The fuse can be electrically connected between the anode and the negative end lead and be configured to fail as a result of a short circuit condition. Voltage is inhibited from passing between the housing and the anode in a short circuit condition due to the failed fuse and the isolator.

Abstract: A system and method for monitoring the health of smart battery packs in an electric vehicle and determining when one or more of the smart battery packs needs to be replaced. In addition, the system and method locate optimal smart battery packs to exchange with the one or more battery packs that need to be replaced.

Abstract: Provided is a battery pack fixing structure and a battery pack replacing apparatus. The battery pack fixing structure comprises a base body, a driving unit, a connecting rod transmission unit and a locking unit, wherein the base body is fixed to an electric vehicle body and configured to supporting the driving unit, the connecting rod transmission unit and the locking unit; the driving unit is configured to supply a driving force; the connecting rod transmission unit is configured to enabling the locking unit to be unlocked under action of the driving force, and enabling the locking unit to be locked after the driving force is removed; and the locking unit is configured to lock the battery pack in a locking state, and to release the battery pack in an unlocking state.

Abstract: A battery for a vehicle having a fixed battery pack and a replaceable battery pack. The replaceable battery pack has electronic or mechanical locks to semi-temporarily hold the replaceable battery pack in place. The fixed battery pack is held in place via permanent or semi-permanent fasteners such as bolts. A battery controller controls the replaceable battery pack to power motors of the vehicle before controlling the fixed battery pack to power motors of the vehicle.

Abstract: A method for managing contents of Video On Demand (VOD) services, where a Middle Ware (MW) controls the stored contents on a VOD server according to the VOD service information correlated with a channel is provided. The corresponding device and system are also provided. Therefore, the specific service forms are separated from the stored contents, and the MW controls the contents in a centralized manner according to the service information; the VOD server does not need to store the contents of each service separately, but adds and deletes the stored contents according to the unified control from the MW, thus avoiding repeated storage of the same data for different services.

Abstract: The present invention discloses an interactive service provision method mainly including: associating a program with interactive service information, acquiring the interactive service information associated with the program and presenting the interactive service information by the set-top box when the program is played, according to interaction attribute of the program indicating that the program is associated with the interactive service information. The invention also provides a corresponding interactive television system. The invention allows the interactive service information to be acquired through the interaction attribute of the program, and thus to be separated from television signals. In addition, it is possible for the user to participate in the interactive service information directly through the set-top box conveniently while watching the program, which is advantageous in facilitating and improving the efficiency of the interactive service, and enhancing the user participation.
