| 20150066273 | METHOD FOR CONTROLLING RECHARGING OF THE BATTERY ON A HYBRID VEHICLE - A method for controlling recharging of a traction battery on a motor vehicle hybrid transmission including a heat engine and at least one electrical machine, wherein the electrical machine is used as a sole motor-driven power source up to a speed threshold beyond which it is possible to couple the heat engine with the wheels, in hybrid modes, to run power supplies from the heat engine and the electrical machine simultaneously with each other. In the method, below the speed threshold, the electrical machine ensures only torque to be transmitted to the wheels, while the heat engine is ignited to provide recharging without contributing to pull of the vehicle when a driver bears on the accelerator pedal, and while the wheels are separate from the heat engine and the electrical machine, when the driver does not bear on the accelerator pedal, to enable recharging of the battery. | 03-05-2015 |
| 20150063897 | SYSTEM FOR LOCKING / UNLOCKING AN OBJECT UNDER A STRUCTURE HAVING A HOOK FOR DRAWING AND SUPPORTING SAME - A system is provided for locking and/or unlocking an object, such as a power battery of a drive engine of an electric or hybrid motor vehicle, under a structure such as a chassis of the vehicle, including a plurality of locks ensuring the attachment of the object under the structure. The locks are secured to the object and/or structure and each include a hook configured for drawing the object to the structure by compressing an elastically deformable member inserted between the object and the structure and for supporting the object relative to the structure at the end of the approximation travel, as well as a transmission device driving the hook during the drawing travel and configured such as to be actuated by an actuation tool that is separate from the structure and the object. | 03-05-2015 |
| 20150056481 | FILLING DEVICE FOR FIREFIGHTERS OF A DRIVE BATTERY OF AN ELECTRIC OR HYBRID VEHICLE - An electric or hybrid vehicle including an arrangement of mechanisms introducing an extinguishing fluid into a battery pack, especially a drive battery, of the vehicle. A first port is placed in a wall of the pack and provides access to an interior of the pack, the first port including a partial or total blocking mechanism being removable or meltable under effect of temperature. A second port is placed in an element of a body of the vehicle facing the first port. Extinguishing fluid may be introduced into the pack through two ports once the blocking mechanism of the first port has been removed or melted. | 02-26-2015 |
