mage, 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。 The battery of NiCd and battery of NiMHs refresh the the electric current method for the ever , and have severals to stop the judgment method for refresh differently. Biggest refresh the electric current biggest refresh the electric current to have relation with battery capacity( C).Biggest usually refresh the electric current to mean with the number of the battery example, The capacity of the battery for 750 mAhs, refresh the electric current as 750 mAs, then refresh the electric current as 1 C(1 times battery capacity).If The electric current to flow refresh is a C/40, then refreshing the electric current for the battery capacity in addition to with the hot battery refresh is the process that the electric power delivers the by chemical reaction conservancy e is not electric powers all convert for the sake of the chemistry in the battery electric power conversions became the thermal energy, having the function of the heating to the pond be filled with, if continue to refresh, then all electric powers conversion is the thermal energy of the fast charge this will make the quickly, if the hour of can not pare with stop refresh and then will result in battery , while design the battery charger, to the is count for much that carry on the supervision bine to stop refresh in time. The discretion method battery stopped refresh of different and applied situation and work environment limitted to the choice of the method that the judgment stop sometimes temperature allow of easily, but can measure electric voltage, or is other text takes the electric voltage variety rate( dV/ dt) as the basic judgment to stop The method for refresh, but with the temperature and absolute electric voltage be worth for assistance and the hardware support that this text describe speaks as method of the havings of say. Time of t – this method that is the decision when stop refresh most in used for spare project of the hour of fast also be .Refresh(14 16 Hour) basic project of the applicable to various refresh when the electric voltage of V – be the electric voltage to outrun the upper with the forever settle the electric current refreshes the match biggest electric current is decide by the battery, usually For the 1 prevent176。 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 judgmen。
