氢燃料与纯电动汽车的技术差异
1
动能条件有一定的差异
纯电动汽车会使用单一的蓄电池,作为汽车的储能动力条件,利用电池向电机提供相应的电能资源,最终实现驱动电机运行的目标,汽车平稳运行。该技术应用的优点,就是无污染、噪声小,所以在环境保护方面,技术应用优势相对较为明显。
新能源汽车——纯电动汽车与氢能源汽车的差异
纯电动汽车内,燃机的汽车结构设置较为简单,在运行过程中,所使用的传动部件较少,所以后续的维修与保养要求也比较少。
氢能源汽车,主要是使用燃料电池驱动系统运行的,燃料电池主要是利用氢气与空气的氧气,经过催化反应之后,实现化学能转化为电能的目标,电化学反应能将化学能源转化为电能资源。在电化学反应过程中,所使用的还原剂主要是氢气,氧化剂则主要是氧气。
新能源汽车——纯电动汽车与氢能源汽车的差异
纯电动汽车充足的充电时间,基本是八个小时左右,而添加氢能源之后,会减少一半的时间,而且氢燃料汽车在一次加氢之后,续航里程显著提升,相对于纯电动汽车有自身的优势。
2
电力来源差异
纯电动车的动力来源,主要是动力电池。通过充电的方式,输送动力电池蓄电,动力电池向电机控制器供电,随后再向电机控制器控制电机,此时车辆运行效率显著提升。
新能源汽车——纯电动汽车与氢能源汽车的差异
氢燃料电池,主要是氢气与氧气形成化学反应之后产生电能,最终实现电机控制能源的目标,驱动电机运行,所以在电力来源方面有所不同。
新能源汽车——纯电动汽车与氢能源汽车的差异
氢燃料汽车的电池,与纯电动汽车的动力电池,本身就有着较大的差异,氢燃料汽车的电池,能够向低压电器供电,而且氢燃料电池前期启动,能更好地满足整车运行的需要,但是纯电动汽车则是一种高压系统,需要逐步向驱动系统供电。
从世界范围的技术应用情况来看,现如今电动汽车技术突破发展,但是氢燃料电池,只有少数国家在技术推广。纯电动汽车以及氢燃料电池汽车,究竟哪种技术,会成为汽车行业的主流,需要关注技术突破情况以及当地的政策情况。
所谓新能源汽车主要是指汽车使用非石油产品做为工作介质的汽车。氢能源应该是非石油工作介质,所以应该是新能源汽车。
工作原理是:氢分子通过燃烧与氧分子结合产生热能和水,氢燃料电池通过液态氢与空气中的氧结合而发电。
氢能的运行机制有四种:电机、能量电池、储氢罐和高压电池。其中,电机负责驱动车轮,能量电池是氢气和氧气发生化学反应的地方,储氢罐是储存燃料的燃料罐,高压电池负责提供空电力和启动车辆的启动动力。
我国的氢能标注体系开始于1985年,当年GB4962《氢气使用安全技术规程》正式发布,该标准规定了气态氢在使用、置换、储存、压缩与充(灌)装、排放过程以及消防与紧急情况处理、安全防护方面的安全技术要求,虽然该标准在2008年进行了修订,但该标准的发布标志着我国开启了氢能标准化。
现在的国家氢能标准包括产品、安全使用、氢氧站设计、制氢储氢等方面的测试方法和技术条件等国标和行标,我国已初步建立氢能标准体系。现在,有一系列的国标正在修订,主要涉及氢能的燃料电池及氢能汽车标准,如质子交换燃料电池术语、质子交换膜燃料电池标准体系、质子交换膜燃料电池堆、便携式质子交换膜燃料电池、固定式质子交换膜燃料电池发电系统、电动汽车用电机及其控制器技术规范、电动汽车用电机及其控制器测试规范、氢能——水电解制氢技术要求、变压吸附提纯氢的技术要求等。
按照电池回收管理办法,氫能源汽车大约5到8年就要报废了。
报废新能源参考燃料汽车:至于新能源车,报废标准完全参照现有燃油车制定,没有单独的报废标准。只要车辆能通过车辆年检,没有问题,那么就可以继续使用,否则就需要报废。对于家用车报废年龄的新规定,私家车现有的标准行驶里程约为60万公里,达到60万公里时,将由国家引导报废。
Wide collect the sources of energy to hydrogenous energy business belongs to hydrogenous the sources of energy.
This is two different companies.
Shanghai the sources of energy is the abbreviation of Inc. of the sources of energy of Shanghai big quarter.
Inc. of the sources of energy of Shanghai big quarter controls share company for Inc. of energy resources of the coal in China, in December 1999 by report of big quarter coal (group) finite liability company is made give priority to initiator to initiate establish. Place was handed in to issue in Shanghai card in August 2001 appear on the market. The company registers the ground to be in Shanghai Pudong, manufacturing base is in churchyard of Jiangsu abundant county.
Wide the predecessor that collects Inc. of the sources of energy is Xinjiang wide collect industrial Inc. , held water 1999, company stock appeared on the market in Shanghai stock exchange in May 2000.
Wide collecting the sources of energy is petro-chemical appear on the market company, advocate battalion with coal, coal chemical industry, oil is core product, energy content flows for the natural gas liquefaction that prop up, coal chemical industry, exploration of oil natural gas develops Wu of 3 great undertaking.
Coal, natural gas and oil are wide the core product that assembles the sources of energy
Will look at present, wide the stock price that collects the sources of energy is reasonable.

The technical difference of hydrogenous fuel and pure electric car
1
Kinetic energy condition has certain difference
Pure electric car can use onefold storage battery, those who serve as a car store active force condition, use batteries to provide corresponding electric energy resource to electric machinery, achieve the goal that drive electric machinery runs finally, the car moves smoothly. The good point that this technology uses, it is free from contamination, noise small, be in so environmental protection respect, technical application dominant position is relative relatively apparent.
Car of new energy resources -- the difference of pure electric car and car of hydrogenous the sources of energy
Inside pure electric car, light the car structure of machine the setting is relatively simple, in moving process, uses drive disk assembly is less, the place maintenance with sequel and maintain the demand is less also.
Car of hydrogenous the sources of energy, basically be to use system of fuel cell drive to move, fuel cell basically is to use hydric with airy oxygen, after reacting through catalysis, achieve the goal of electric energy of chemical energy translate into, electrochemistry reacts can resource of electric energy of translate into of will chemical the sources of energy. In electrochemistry reaction process, uses reducer basically is hydric, oxidizer basically is oxygen.
Car of new energy resources -- the difference of pure electric car and car of hydrogenous the sources of energy
Pure electric car charges amply time, basic it is 8 hours left and right sides, and after adding hydrogenous the sources of energy, can reduce the time of the half, and hydrogenous fuel car is in after hydrogenation, add boat course of development promotes significantly, relative to Yu Chun electric car has the advantage of oneself.
2
Power source difference
The dynamical source of pure report motor-car, basically be dynamical cell. Carry charging kind, carry electricity of dynamical cell harbour, dynamical cell to power supply of electric machinery controller, dominate electric machinery to electric machinery controller again subsequently, right now car runs efficiency to promote significantly.
Car of new energy resources -- the difference of pure electric car and car of hydrogenous the sources of energy
Hydrogenous fuel cell, basically be hydric electric energy produces after forming chemical reaction with oxygen, final implementation electric machinery dominates the end of the sources of energy, drive electric machinery moves, differ somewhat in power source respect so.
Car of new energy resources -- the difference of pure electric car and car of hydrogenous the sources of energy
The batteries of hydrogenous fuel car, with the dynamical cell of pure electric car, itself is having bigger difference, the batteries of hydrogenous fuel car, can to power supply of low-pressure electric equipment, and early days of hydrogenous fuel cell is started, can satisfy better truckload the need that move, but pure electric car is system of a kind of high pressure, need is progressively to drive system power supply.
From the point of worldwide technical application circumstance, show technology of electric nowadays car to break through development, but hydrogenous fuel cell, only a few country is popularized in the technology. Pure electric car and car of hydrogenous fuel cell, after all which kinds of technology, can make the main trend of automobile industry, need pays close attention to a technology to break through the policy circumstance of circumstance and place.
Car of alleged new energy resources basically is to show the car is used be not petroleum products the car as working medium. Hydrogenous the sources of energy should medium of dispute oil job, should be car of new energy resources so.
Working principle is: Hydrogenous element produces heat energy and water through combustion and oxygen element union, hydrogenous fuel cell is united in wedlock through the oxygen in liquid state hydrogen and air and generate electricity.
Hydrogen can moving mechanism has 4 kinds: Chu Qing canister and batteries of electric machinery, energy, high pressure batteries. Among them, electric machinery is in charge of drive wheel, energy batteries is hydric the place that reacts with aerobic happening chemistry, chu Qing canister is to store the fuel canister of fuel, high-pressured batteries is in charge of offerring empty electric power and the starting motivation of the car that start.
The hydrogen of our country can tag a system to begin 1985, in those days GB4962 " hydric use emergency decree " release formally, this standard stipulated gaseous hydrogen is being used, displacement, store, compress with fill (fill) outfit, platoon lets off Cheng and fire control and emergency processing, safety to defend the safe technology of the respect asks, although this standard undertook editing 2008, but the issuance of this standard is indicating our country open hydrogen can be standardized.
Present national hydrogen can the standard includes product, safety to use, the GB such as the test method of the respect such as the oxyhydrogen station design, Chu Qing that make hydrogen and technical condition and travel mark, our country is preliminary already build hydrogen can standard system. Now, have a series of GB is editing, basically involve hydrogen can fuel cell and hydrogen can car standard, if proton exchanges exchange of fuel cell term, proton,system of standard of velar fuel cell, proton exchanges caboodle of velar fuel cell, portable proton to exchange proton of velar fuel cell, stationary to exchange velar fuel cell to generate electricity system, electric car reachs his with electric machinery controller technology standard, electric car is reached with electric machinery.
Reclaim according to batteries administrative measure, car of the sources of energy about 5 be about to discard as useless to 8 years.
Discard as useless: of car of fuel of reference of new energy resources? Bad attentively walks on Mo to enter daughter-in-law of the ǚ that carry to sunlight of age over sixty years of age grasps barrier bell raw meat or fish to add all to touch daughter-in-law of ǚ of Lai Mou of ザ of instrument of brandish of deficient ǎ to sunlight of Guo of serve of form of brandish of of Yu of covered with clouds of moxibustion of pilfer of of ü of Gorgon euryale of moxibustion of pilfer of flesh V grey knocks honest, when achieving 600 thousand kilometer, will discard as useless by national guiding.
