Abstract
The utility model is an electricity output control system for an electric vehicle driven by a composite fuel cell, which makes the electricity source be selectable via an optimized design for a DC/DC converter and by using a controller area network (CAN) as the communication tool. The utility model is equipped in an electric vehicle. When the vehicle is in a light-load state (e.g. cruising at a constant speed), the fuel cell supplies electricity and is boosted to an appropriate voltage via the control of the DC/DC converter, and the fuel cell can also be used as an on-board charger. When the vehicle is in a heavy-load state (e.g. instant acceleration or climbing a slope), the fuel cell supplies the maximum base-load electricity, the other part of the required electricity is supplied by a high power second battery; therefore the system has composite electricity output control function and overcomes the shortcomings of conventional minitype electric vehicle such as poor continuous cruising distance and bad energy conversion.
Description
Technical field
The utility model relates to a kind of electric power output control system of electric vehicle with combined fuel battery, especially a kind of communication by controller local area network's interface, integrate one direct current (DC)/direct current (DC) conv, a polymer electrolyte fuel cell and small-sized a, lightweight and high-power secondary battery ... etc. electric power source, make electric system maintain the elec. vehicle electric power source control system of the combined type electric energy of preferable serviceability.
Background technology
Self-propelled vehicle is exactly the maximum walking-replacing tool of China's quantity for a long time, because of it possesses the characteristic that light and handy, fuel-efficient and convenient parking are arranged, so self-propelled vehicle almost becomes the vehicle of each family's indispensability, but recent years environmental consciousness raising (concentration of carbonic oxide and hydro-carbon raises in the air, seriously destroy atmospheric structure), therefore all formulate strict discharging gas standard for vapour, self-propelled vehicle, and the self-propelled vehicle of four-stroke has preferable discharging gas standard, therefore little by little replaces the main flow that two stroke self-propelled vehiclees become market.Though there is third and fourth more harsh phase environment protection emission gas standard just preparing to implement now, the environmental protection final objective is to be to make vapour, self-propelled vehicle to reach zero standard of polluting.
For above-mentioned purpose, successfully develop at present and do not use the steam turbine motor-car of gasoline as fuel, change with the lead-acid battery of rechargeable type source as electric energy, in order to replace conventional engine, so just can reach zero standard of polluting, but its flying power not good (charging finishes, and the back is about can only travel about 60 kilometers), and charging duration (needs about eight hours approximately) too for a long time and battery-charging station is very little ... etc. shortcoming, therefore make relevant dealer can't effectively do an expansion, and cause customer's purchase intention not high.And the utility model is at the shortcoming of conventional electric self-propelled vehicle and does an improvement, and develops a brand-new electric power output control system, and can make elec. vehicle (as self-propelled vehicle and bicycle ... Deng) possess preferable flying power is arranged.
Other is the person, polymer electrolyte fuel cell (Polymer Electrolyte MembraneFuel Cell, PEMFC), be development in recent years fast speed fuel cell the most, compared to other kind types of fuel cells, be to have normal temperature (below 80 ℃) quick active and the sensitive advantage of dynamic response (Transient Response), might be widely used in future in the electric system of movable types (Portable) such as steam turbine motor-car, polymer electrolyte fuel cell adopts airborne oxygen and hydrogen fuel to do a reaction, this course of reaction is similar electrochemical adverse reaction phenomenon, in the course of reaction except producing electric energy and water, also produce used heat in addition, but can not discharge material, so polymer electrolyte fuel cell is the optimal selection of the peace and quiet energy of vehicle with toxicity.
The discharge characteristic of polymer electrolyte fuel cell, according to its film group body (MembraneElectrode Assembly, characteristic MEA) is and different, its following factors all can exert an influence:
(1) gas diffusion layers: number and shape, thickness, drainage and the electric conductivity in its in-to-in film group body opening hole all can exert an influence.
(2) active layer: content, grain size and the distribution scenario of its in-to-in catalyst kind, composition, noble metal all can exert an influence.
(3) PEM: its in-to-in thickness, aqueous ingredients, pore space structure, hole size and number all can exert an influence.
Referring to Fig. 1, it is characteristic (discharge characteristic) diagram of curves of the density of current-voltage of traditional fixedly high molecular fuel battery, also be called polar figure (PolarizationCurve) or (Tafel Curve), be to be the fixing discharge performance in high molecular fuel battery when reaction of representative type, under the standard environment of room temperature (25 ℃), generation one is the water of ear not, during its heat content (Δ H °) be-286kJ/mole, the Gibbs free energy (Δ G °) that can be converted into electric energy is-237kJ/mole, therefore, theoretical power yield just reaches 83%, remaining-49kJ/mole (S ° of T Δ) is the used heat that disengages then, and polymer electrolyte fuel cell is because of the electrochemical reaction of this normal temperature, compared to conventional engine such as combustion engines, have higher energy conversion efficiency.Its discharge characteristic by in the polar figure as can be seen:
A-quadrant, fuel cell are subjected to the influence of activation loss (Activation Loss) when output LOW current density, during zero current (non-loaded), magnitude of voltage can't reach theoretical value (1.23V), when the output low current density, magnitude of voltage descends fast, and obviously presents non-linear.
The B zone, the energy loss of generation is subjected to the influence of interior resistance (Ohmic) when mainly being the transfer of proton and electronics, be following four important parameters: the electrical impedance of electrode conductor, cathode impedance reaction, anode impedance reaction, electrolyte impedance ... Deng.The i.e. linearly ratio reduction of this regional voltage along with the increase of density of current.
The C zone, the density of current of output reaches the highest, the reason of its loss is when being to take place big quantitative response, reacting gas (air and the hydrogen) molecular number that needs is more, only the transmission of reacting gas, proton is subjected to the restriction of mass transport (Mass Transfer), having little time provides the molecular number of reacting required, causes the rapid decline of magnitude of voltage.
Based on the shortcoming that solves the above conventional art, though this traditional elec. vehicle has low noise and can not cause the air-polluting characteristic, but still have that charging duration is long, cruise duration short, and the weight of battery (lead battery) too heavily reach the electrically-charging equipment deficiency ... etc. problem, all make traditional elec. vehicle be subjected to great restriction.
