【正文】 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 damage the battery wrap, needing to supervise and control the electric voltage without a unit electric voltage Descend the Vs must shut battery of NiCd carries on refresh in settling the electric current by forever . The NiMH hydrogen battery( NiMH) holds to shoot the elephant machine such as the cellular phone, hand in the hand that the importance measure hold equipments, the etc. NiMHhydrogen battery is an usage the most kind of battery quantity is bigger than NiCd39。s is what and simple with the deluxe of C this design is very Carry on adjust easily to suit current and future the ATtiny15 reference design then use edit collected materials the language to write of, with Acquire the biggest code density. An electric appliances of the modern consumption mainly uses as follows four kinds of batteries: pletely the sour battery of lead( SLA) battery of NiCd NiMHhydrogen battery( NiMH) battery( Li Ion) At right choice battery and refresh the calculate way need to understand the background knowledge of these batteries. Seal pletely the sour battery( SLA) of lead seals pletely the sour battery of lead to mainly used for the more important situation of the cost ratio space and weights, such as the UPS and report to the police the backup battery of the system. The battery of SLA settles the electric voltage to carry on , assist limits to avoid with the electric current at refresh the process of early battery lead the ～ only the electricity .The pond unit electric voltage does not exceed the provision( the typical model is worth for the Vs) of produce the pany, the battery of SLA can refresh without limit. The battery of NiCd battery of NiCd use very widespread advantage is an opposite cheapness, being easy to the usage。The design of the lithium battery charger Introduction LiIon rechargeable batteries are finding their way into many applications due to their size, weight and energy storage batteries are already considered the preferred battery in portable puter applications, displacing NiMH and NiCad batteries, and cellular phones are quickly being the second major marketplace for LiIon. The reason is clear. LiIon batteries offer many advantages to the end consumer. In portable puters, LiIon battery packs offer longer run times over NiCad and NiMH packs for the same form factor and size, while reducing weight. The same advantages are true f
