Abstract
The invention belongs to the technical field of equipment manufacturing industry, and relates to a quick charge method for a lead battery of an electric vehicle. The method of the invention adopts the technical scheme of combining depolarization pulse charge and parallel charge, and comprises the following steps: during initial charging, after charging for 2min by current of 170A, front stopping for 25ms, then carrying out negative pulse discharging for 50ms by current of 300A, back stopping for 25ms, then continuing to charge by high current, cyclically charging in such a manner until the voltage achieves 17V, and then changing to a parallel charging stage. In the charging process, with the increase of the electrolyte concentration, the terminal voltage continuously increases and the polarization distribution condition follows to change, the ohmic voltage drop in the polarization and the charging current meet the ohm law, while the concentration polarization obviously increases when approaching gassing, and the gassing is necessary to be eliminated in time for continuing quick charge.
Description
Technical field: the invention belongs to the equipment manufacture technical field, relate to a kind of electric motor car lead accumulator fast charge method.
Background technology: the application of lead accumulator is very universal now, the technical indicator and the progress of the lead-acid battery that proposes according to the advanced lead-acid battery federation in the world (ALABC), charging requirement to battery is 50% of the capacity that charges in the 5min, fill 80% of people's capacity in the 15min, 4h charges into capacity 100%.Usually storage battery adopts the syllogic charging method, also do not obtain under the situation of remarkable breakthrough at the current battery charging technique, this charging method is finished an initial charge needs time about 10～15h approximately: charging is given the development of electric motor car and is popularized and bring very big inconvenience so for a long time, also greatly differ from each other, become the bottleneck of restriction electric motor car development thus with the technical indicator that will reach.
Facts have proved that strengthening charging current merely, to shorten the charging interval be infeasible, because charging like this. not only storage battery does not reach rated capacity, and the storage battery temperature rise is accelerated, and produces a large amount of bubbles, causes active material to come off and influences its cycle life.
Summary of the invention: the objective of the invention is to adopt the method for efficient depolarising fast pulse charger in conjunction with constant voltage charge in parallel, utilize two kinds of methods pluses and minuses separately to realize having complementary advantages, reduce the charging interval, strengthen the conforming fast charge method of battery electric quantity.
The present invention is achieved like this: adopt the technical scheme of depolarising pulse current charge in conjunction with charged in parallel, during initial charge, after 170A current charges 2min, before rest 25ms, then with 300A electric current negative pulse discharge 50ms, after rest 25ms, and then continue large current charge, so cycle charging reaches 17V and changes the charged in parallel stage over to until being charged to voltage.In the charging process along with the rising of concentration of electrolyte, terminal voltage also constantly raises and the polarization distribution situation also changes thereupon, satisfy Ohm's law between ohm voltage drop in the polarization and the charging current, and concentration polarization obviously increases near gassing the time, must in time eliminate just and can continue quick charge.
Embodiment: the present invention is described below in conjunction with embodiment.
Embodiment: technical scheme, during initial charge, after 170A current charges 2min, before rest 25ms, then with 300A electric current negative pulse discharge 50ms, after rest 25ms, and then the continuation large current charge, so cycle charging reaches 17V and changes the charged in parallel stage over to until being charged to voltage.After carrying out two stage constant current charges first, test its electric weight, and carry out charged in parallel subsequently 3 times, result of the test shows, charged in parallel can obviously reduce standard deviation between capacity than serial connection charge, and along with increasing of charged in parallel number of times, the capacity difference between battery is further dwindled, and standard deviation has the trend that reduces.If the long-term charged in parallel that uses more can suppress the expansion of standard deviation, to the battery pack later stage, especially the back influence in 1/3 period in life-span is bigger.
At the present situation of current electric motor car, tested the method for depolarising pulse current charge in conjunction with charged in parallel.Under the situation that result proof obviously shortened in the charging interval, and strengthened the consistency of each battery SOC of battery pack, adopt the depolarising pulse in conjunction with the method for charged in parallel to battery of electric vehicle follow-up promote the use of certain actual with reference to meaning.
The inventive method can shorten the charging interval of storage battery greatly, and the charging interval of storage battery also is the bottleneck that present electric motor car is popularized and promoted, strengthened the consistency of each battery SOC of battery pack, crucial effect has been played in the raising and the prolongation in useful life to the service quality of battery pack, before charging technique did not still have big breakthrough at present, technical scheme of the present invention was the method for mature and feasible.
