Fig. 2 is the birds-eye view of the preferred embodiment of the present invention.
Description of reference numerals: 1-storage hydrogen bottle; The 2-electrical motor; 3-charging contact; The 4-vehicle frame.
The specific embodiment
Hydrogen-electric heavy truck provided by the present invention is to convert on the basis of existing homemade tractor-truck, describes with regard to the preferred embodiments of the present invention below.
At first, remove former car diesel motor, water tank, fuel tank and air inlet-outlet pipe.Simultaneously, keep former vehicle carriage 4, operator's compartment, front and back bridge, power steering system, power drive system, suspension, brake system, wheel, lead-acid battery and low-voltage lighting system etc.
The modified segment of hydrogen-electric heavy truck comprises: hydrogen gas storage device, hydrogen cell, inverter, driving motor and controller, chemical battery sets and boosting battery.
Described hydrogen gas storage device comprises: 8 150 liters aluminium courage carbon fiber storage hydrogen bottle 1, and in order to replace original fuel tank.In the present embodiment, storage hydrogen bottle 1 is positioned on the vehicle frame 4 and vehicle frame 4 both sides.Yet according to different vehicles, the placement location of hydrogen gas storage device is also different.The internal pressure of every storage hydrogen bottle 1 is 35MPa, and 8 storage hydrogen bottles are installed in parallel, and have 1200 liters total volume.One end of storage hydrogen bottle group in parallel connects hydrogen cell, and the other end connects the hydrogenation mouth, is provided with breather check valve in this hydrogenation mouth, so that be connected with the equipment that hydrogen is provided.The size of storage hydrogen bottle 1 can change with the variation of vehicle.
Described hydrogen cell utilizes the reaction between hydrogen and the oxygen to generate electricity, and wherein hydrogen promptly store up hydrogen bottle 1, and oxygen is from atmosphere from hydrogen gas storage device.Hydrogen cell and inverter electrically connect, and inverter electrically connects with the controller that is used for control motor 2 again.Therefore, the direct current (DC) that hydrogen cell sends becomes alternating current by inverter earlier, then by controller drives alternating-current motor/AC motor 2, thus powered vehicle.In the present embodiment, select rating horsepower 120kW for use, the hydrogen cell of 600V rated is with hydrogen cell all right two platforms generatings in parallel.Forming water after the hydrogen cell generating is distributed in the atmosphere, to zero environmental again; Again because the employing hydrogen cell substitutes diesel motor, therefore to environment zero-emission carbon.
Described driving motor 2 is selected for use and is exchanged air-cooled situation pole motor, and its rated voltage is 600V, and rating horsepower is 100kW, and peak power is 150kW.Air-cooled special inverter and controller rated capacity are 125kW, and peaking capacity 180kW, the blower voltage of cooling controller are 24V.The output shaft of described electrical motor links to each other with progressive gear transmission, thus powered vehicle.
Described chemical battery sets is selected ferric phosphate lithium cell in the present embodiment for use.The cell specification of described ferric phosphate lithium cell is 3.2V 55Ah, and total voltage is 600V.Ferric phosphate lithium cell increases greatly than the number of times that discharges and recharges of common batteries even lithium cell, thereby has prolonged service life.Described chemical cell electrically is connected with described hydrogen cell, exterior charging equipment and electrical motor respectively.The charging source of described chemical battery sets has two: the one, and utilize the remaining when driving electric power of hydrogen cell to store into this chemical battery sets; The 2nd, utilize exterior charging equipment (3-380V alternating current) to charge to chemical battery sets.Because battery discharge mainly is to consume in vehicle launch and climbing operating mode, so chemical battery sets do not need omnidistance power supply, thereby can correspondingly extend the life of a cell.Wherein, the charging contact 3 of charging equipment preferably is positioned at the bottom of vehicle cab, the one, be convenient to the staff it is charged, the 2nd, consider that hydrogen proportion in the storage hydrogen bottle group is than light many of atmosphere, therefore hydrogen is positioned at the top of storage hydrogen bottle group, and can not accumulate near the charging contact 3 of charging equipment, guaranteed electrically-charged safety.
In addition, owing to cancelled diesel motor, all stopped work by the power steering pump with intergral reservoir of its direct drive, air conditioner compressed pump, brake air pump, warming water tank pump, glass defogger etc., therefore must use above-mentioned each pump of driven by power instead, provide power supply by boosting battery.Wherein especially need to prove,, control brake is carried out electrically-charged strategy earlier with the accessory feed of storage tank, guaranteeing brake air pump normal operation, thereby guarantee traffic safety when the power pack of vehicle being carried out electrically-charged the time.
Hydrogen-electric heavy truck of the present invention is carried out the calculating of dynamic property, draw its maximum speed 70Km/h, climbable gradient 23%, once charge continual mileage near 100Km, and because use emphasis of the present invention is not at express highway, but be subjected to strict area of limiting in discharging and noise, as in the building and camp sites such as cavern and tunnel, therefore the above-mentioned speed of a motor vehicle and travelled distance can satisfy daily driving cycle.If occur prolonging the market demand of continual mileage later on, increase hydrogen container or store up hydrogen pressure and can solve.
Hydrogen-electric heavy truck of the present invention will use two kinds of power supplys, and the electric power that hydrogen cell provides is inseverable main power source, also can not use in conjunction with chemical cell, and just accelerating ability and climbable gradient are affected.Because ferric phosphate lithium cell is very expensive, for cost-cutting, can there be limited region to use even be not contained in the car yet, certain two kinds of power supplys better effects if that combines guarantees that accelerating ability and climbable gradient are necessary to most of lorries.Also can use Hi cell separately, its travelled distance is very short, has an opportunity when removing hydrogenation before moving vehicle to use, so the device of cutting off the electricity supply also is installed on the lorry, can cut off the device of chemical cell.
Two kinds of sample cars are arranged among the present invention, and one is hydrogen-electric heavy truck, and this normal-type wagon, wheelbase need not changed, and hydrogen container all is loaded on vehicle frame 4 both sides under the loading space, the wide 2.5m of former model length overall 12m, and gross weight 26t can bear same transportation burden.This vehicle was once selected for use for vehicle mounted hydrogen producing hydrogenation station.Another is the traction superimposed trailer, is traction power with hydrogen.The traction superimposed trailer uses former model, but this axletree on the vehicle frame 4 of driving rear side, be adorned storage hydrogen bottle group apart from lengthening 1.0m.The superimposed trailer of standard can be adorned 1 12m or 2 6m freight containers, and is the same with the diesel oil heavy motor vehicle, can bear same task.Different is that fuel is different, it is advantageous that with hydrogen to substitute oil, realizes that simultaneously zero pollutes and zero-emission carbon, for automotive energy-saving emission-reducing plays a leading role.
Only the above, only be preferred embodiment of the present invention, when can not limiting scope of the invention process, so the displacement of the change of numerical value or equivalent elements such as with this, or, all should still belong to the category that patent of the present invention contains according to equalization variation and modification that the present patent application claim is done.
