Description
Technical field
The invention belongs to electronic technology and accumulator charging technology field, relate to a kind of electric vehicle battery vulcanization removing no power supply transformer charger.
Background technology
The capacity of lead acid accumulator (storage battery) is large, the sexual valence height is that present various rechargeable battery is incomparable.The particularly research and development of maintenance free cell success makes the field of its application more extensive.At present, the automobile-used battery of electrical salf-walking generally adopts maintenance-free lead accumulator as power source, so the quality of accumulator property directly affects the properties of electric bicycle.Therefore, how to use, maintenance free cell is the thing that the consumer is concerned about the most.Although storage battery has very large pardon to charging modes, if use for a long time charger inferior can accelerate the aging and capacity fast-descending of storage battery, thereby cause the electric bicycle course continuation mileage to shorten, lifting capacity descends, and main cause has:
The general battery charger of ⒈ is by after the AC transformer step-down, obtains direct current through bridge rectifier or with the Switching Power Supply mode.No matter charger takes the charging of unsteady flow mode or current constant mode when work, charge circuit is in conducting (charging) state all the time.Therefore, it is very high that charger requirement charging current can not be set, and generally is located at 0.5～2A.Because of charging current less than normal, thereby cause the effect of removal pole plate sulphation (that is: salinization) of charging voltage and strength of charging current not obvious;
The ⒉ storage battery moves under the power shortage state of being everlasting, or often is in over-discharge state;
⒊ charge in batteries overlong time can cause storage battery aggravation dehydration, and electrolyte (dilute sulfuric acid) is dry too early because of dehydration, easily causes storage battery to fill drum, distortion, makes the service lifetime of accumulator premature termination;
⒋ utilizes and to overcharge or with the way of large current charge, turn usefulness into though can increase the desulfuration lead plumbate, and it has little effect, and diminishes accumulator property.In charging process a large amount of electric energy be used as that water in the dilute sulfuric acid solution is electrolyzed to produce hydrogen and oxygen and dehydration (phenomenon is for producing bubble, that is: the gas of generation is to go out oxygen from anode, goes out hydrogen from negative electrode, its volume ratio O
2: H
2=1:2, the main cause that electrolyte reduces in the battery use procedure that Here it is), storage battery also produces a lot of heats thereupon;
Lead sulfate (salinization) to accumulator plate during the general charger charging of ⒌ forms unrestraint effect (although storage battery has very large pardon to charging technique), and the sulfation of pole plate is irreversible process.The charger that Long-Term Properties is relatively poor can cause adverse effect to accumulator property, and this adverse effect can be accumulated over a long period.
Since the use of electric bike battery or safeguard improperly can cause all that its capacity descends rapidly, significantly shorten useful life (early ageing).The common charger kind that is used for charge in batteries on the market is more, but charging effect is generally not good enough, and the overwhelming majority does not have repair function.How reaching normally or longer life span, has been the problem that the storage battery user is concerned about the most.
Use the power frequency supply transformer to make to exist the problems such as volume, weight are large always, and use Switching Power Supply to have the practical problems such as cost of manufacture is high, fragile.
