ABSTRACT

Numerous advantages of the lithium-ion battery make it acquire the extensive application in small scaledly then hold equipments, but different from chrome of nickel , the nickel hydrogen battery is the lithium-ion battery to need the safety to refresh the control efficiently, and along with the further development that the intelligence turns the degree, need a lithium battery of high accuracy monitor electric circuit urgently to control the battery appearance completely, decide to control the strategy, thus raise the system movement credibility.Owing to this, this text on the foundation of the development trend, the function characteristics of the analytical lithium-ion battery, pointed out an urgency for study and possibilities, put forward a kind of design project that refreshes the electric circuit according to the MAX1758 lithium-ion battery, and verified its possibility.Put forward at the same time a kind of according to DS2762 of lithium battery monitors the design project of the electric circuit and expand in the possibility way of thinking of this DS2762 monitor electric circuit foundation, the concrete contents include the chip characteristic, leading the feet function, the hardware connect electric circuit with to apply software process etc..Tallied up a work target for study finally, the research makes progress and adapts the circumstance.
