【正文】 attery of NiMH lose efficacy, carry on measuring by the square in refresh process is count for much in fit to battery of NiCd, the pole turn over the battery also will damage. Battery of NiMH of from turn on electricity the rate and is probably 20%/ to battery of NiCd, the battery of NiMH also settles the electric current to refresh .Other batteries says pare in lithium battery( Li Ion) and this texts, the lithium battery has the tallest energy/ weight to pare to pare with energy/ physical battery Settle the electric voltage to carry on refresh with , want to have the electric current restrict to lead the heat in the early battery of refresh the process by avoid at the same refresh the electric current Descend to produce the minimum electric current of the enactment of pany will stop to refresh will result in battery damage, even exploding. The safety of the battery refreshes the fast charge machine( namely battery can at small be filled with the electricity in 3 hours, is usually a hour) demand of the to the unit electric voltage, refresh the electric current and the battery temperatures to carry on to measure by the square, avoid at the time of being filled with the electricity because of leading to in of the method SLA battery and lithium batteries refreshes the method to settle the electric voltage method to want to limit to flow for the ever 。froming refresh the electric current leads to causes battery lead greatly hot, the restrict of the electric current at this time very method Is a lithium battery basic to refresh and stop project. The actual lithium battery charger usually still continues into after attain biggest electric voltage Go the second stage refresh, to attain 100% battery capacity. For battery of NiCd and battery of NiMHs are originally method can Be the spare judgment stops refreshing the project. The method exploitation that this judgment of the dV/ dt – electric voltage variety rate stops refresh negative electric voltage variety the battery of some types, be the battery to be filled with the subsequence Refreshing continuously will cause electric voltage descend. At this time this project was very method usually useds for the ever to settle the electric current to refresh, Be applicable to to the fast charge of the battery of NiCd and battery of NiMH. The electric current of I – is to refresh the electric current small in a certain the number that set in advance stop refresh. Usually used for the ever to settle the electric voltage to refresh the applicable to the SLA Battery and lithium T – temperature absolute zero can be the basis that battery of NiCd and battery of NiMHs stop refresh, but even suited for to be the backup battery for temperature to outrun initial value have to stop basis that the dT/ dt – temperature rising velocity fast charge variety rate of the temperature of hour can be to stop consult the norm that the battery produces the pany( battery of NiCdOf typical model be worth for the 1 oC/ min) the – be applicable to the battery of NiCd and battery of to stop refresh when the DT – outrun the temperature value of the environment temperature to be the bad battery temperature and the environment temperature to exceed the certain
