摘要:
A power transmitting system for hybrid vehicle with first and second planetary gear mechanisms of different ratios used for power derivation: a first planetary gear mechanism (4) dedicated to low vehicle speeds and the second planetary gear mechanism dedicated (5) to the high vehicle speeds. The planetary gear mechanisms are driven in parallel by a thermal engine (1) and by an electric motor (2). The planetary gear mechanisms drive, in parallel, a differential gear (6) connected to wheels (9). Pilot shafts of the planetary gear mechanisms (4) and (5) alternatively connect and disconnect to an electric generator (3) which regulates the driving force of the vehicle by controlling resistive torque through a clutch (7). Advantages of the system include improved efficiency, reduced cost, regenerative braking and power input from an electrical grid.
摘要:
The invention relates to a system for installing or uninstalling a removable battery of an electric or hybrid vehicle characterized in that the system is fully integrated in the vehicle and does not require any outside assistance. To summarize, the jack (3) can vertically handle and drop the battery (2) when the locks (4) securing the battery below the vehicle (1) floor are open. For reinstalling the battery, the parking assistance system of the vehicle guides the vehicle above the battery, whereas the lifting device can cope with the unavoidable positioning errors. This battery dropping system is useful for batteries exchange, batteries renting or maintenance, and for adapting the battery's configuration to the forecasted loads or usages of the vehicle. Important cost and fuel savings along CO2 emission cuts are expected from this device. In fact, the vehicle no longer carries a heavy battery when it is not necessary. Even more, adapting batteries to vehicle usages allows decreasing vehicle design loads with impacts on costs and vehicle performances. In addition, the device can also be used as an automatic and high-power electrical connector.
摘要:
A hybrid vehicle having a series-parallel architecture, i.e. a mechanic (gears) and an electric (generator (4), inverter (7), and motor (6)) propulsion chains associated by a planetary gear mechanism (2) powered by an engine (1). The generator rotor (4), with or without a flywheel (3), provides a kinetic energy storage due to its high inertia and speed. The stored energy is sufficient to drive simultaneously, the vehicle at low speed, and the not-fueled engine (1), during short periods. Between these periods, the fueled engine drives the vehicle and restores the stored kinetic energy. The succession of these periods made operation pulsatile at higher maximum power. Higher power means better efficiency. In addition, less pollution and perturbation compare to the “stop and start” are expected.
摘要:
A series-parallel hybrid vehicle which uses two planetary gear mechanisms, the first one (4) dedicated to low vehicle speeds and the second (5) dedicated to high vehicle speeds. The two planetary gear mechanisms include pilot shafts (3rd shafts) which are alternatively coupled to an electric generator (3); output shafts which drive the wheels (9) through a differential (6); and input shafts which receive power from an engine (1). An electrical motor (2) drives the wheels in parallel with the two planetary gear mechanisms. A flywheel (85), less than 1% of the vehicle weight, is coupled to the generator (3) to store kinetic energy of the vehicle during decelerations. The planetary gear mechanisms makes possible higher efficiency at low vehicle speeds where decelerations are frequents. The energy storage performance of the flywheel equals that of ultra-capacitors.The system provides improvements regarding over torque protection and power-train arrangement.

摘要:
The patent applications U.S. Ser. No. 13/118662 have for object a hybrid vehicle which uses two planetary gears mechanisms for its power derivation, one (4) dedicated to the vehicle low speeds and the second (5) dedicated to the vehicle high-speeds.To improve this device, a small flywheel (85), less than 1% of the vehicle weight, is coupled to the generator (2) to store the kinetic energy of the vehicle during deceleration. The double planetary gears mechanism makes possible to have, a high effectiveness at vehicle low speeds where the decelerations are frequent and little effect at vehicle high speed where the decelerations are less frequent, where they are often too powerful for the existing devices and where we should not harm the vehicle inertia.The storage performances equal those of today ultra-capacitors.The system brings also some other improvements regarding over torque protection and regarding power-train arrangement.
摘要:
A hybrid vehicle with high energy efficiency due to two planetary gear mechanisms of different ratios used for the power derivation: one planetary gear mechanism (4) dedicated to the low vehicle speeds and the other (5) to the high vehicle speeds. The two planetary gear mechanisms are driven in parallel by the thermal engine (1) and by the electric motor (2). They drive themselves in parallel the differential gear (6) of the axle which is connected to the wheels (9). The pilot shafts of the two planetary gear mechanisms (4) ad (5) are alternatively connected and disconnected to the electric generator (3) which regulates the driving force of the vehicle by controlling its resistive torque through the clutch (7). This specific architecture brings: a better energy efficiency thus less fuel consumption, less powerful electric equipment's thus less expensive, and some specific possibilities regarding an electric braking and regarding some fuel substitution for electricity from the national grid.

The invention relates to a system for installing or uninstalling a removable battery of an electric or hybrid vehicle characterized that the system is fully integrated and does not require any outside assistance. To summarize, the jack (3) can vertically handle and drop the battery (2) when the locks (4) securing the battery below the vehicle (1) floor are opened. The unavailable vehicle positioning against the battery dropping location is characterized that it uses the parking assistance system (5) of the vehicle while the device can compensate the inaccuracy gap. This battery dropping system is useful for batteries exchange, for batteries renting or maintenance, and for adapting the batteries configuration to the forecasted load or usages of the vehicle. Important cost cuts, CO2 cuts and fuel savings can be expected from these possibilities. In fact, the vehicle no longer carries a heavy battery when not necessary. Even more, adapting batteries' weight according to vehicle load allows decreasing the maximum load design which impacts costs and performances. In addition, the device can also be used as an automatic and high-power electrical connector. Such connectors are more and more required for quick charger while they are less and less hand able for human.
