Description
Technical field
The utility model belongs to the lithium battery control device, is specifically related to a kind of lithium thionyl chloride cell capacity management circuit.
Background technology
Lithium thionyl chloride cell is widely used on the instrument and meters such as domestic water meter, ammeter, gas meter because of its high power capacity and long-life characteristics, and these instrument and meters require the serviceable life of batteries at least more than 6 years.Because of the consumption information that is writing down the user on these instrument and the information of paying the fees, the requirement height to battery does not allow to occur power-down conditions, otherwise loss of data can take place, and causes damage to the user.
Because the lithium thionyl chloride cell open-circuit voltage is stable, open-circuit voltage is stabilized in more than the 3.65V always when battery capacity is not intact, and battery remaining power and open-circuit voltage do not have corresponding relation; The load voltage of lithium thionyl chloride cell is also very steady, and the corresponding relation of the residual capacity of load voltage and battery is not obvious, and the hysteresis characteristic of lithium thionyl chloride cell can interference load the corresponding system of voltage and capacity.Therefore can not determine the residual capacity of battery with the method that detects open-circuit voltage or load voltage.
The method that the current battery user takes is: according to the consumption of the power consumption calculation battery capacity of design circuit, and time of battery is changed in decision in view of the above.But the humiture environment that the parameter of side circuit power consumption and components and parts and quality, instrument are used, instrument user are directly related to the behaviour in service of instrument etc., with the power consumption of design very big difference is arranged, such result will cause two kinds extreme: once be not to design service time battery capacity exhaust, can cause the loss of data of instrument record like this, the 2nd, battery also remains a lot of capacity during to service time of design, and such battery is replaced and can causes unnecessary waste.
Summary of the invention
The purpose of this utility model is to provide a kind of lithium thionyl chloride cell capacity management circuit that can realize the capacity consumption of real-time monitoring battery, to address the above problem.
The technical solution of the utility model is: lithium thionyl chloride cell capacity management circuit, it comprises sampling resistor, the two ends of sampling resistor are connected with the voltage sample unit, the output terminal of voltage sample unit connects microcontroller, microcontroller is output as alarm control signal, described microcontroller is the capacity consumption amount that the voltage signal values that is used for gathering is converted to real-time monitoring battery, and the capacity consumption amount is compared the output alarm control signal with the design capacity of battery.
Described alarm control signal connects sound and/or optical alarm circuit.
The alarm control signal of microcontroller connects the wireless communication signals transtation mission circuit.
This circuit can be realized the capacity consumption of real-time monitoring battery, and compares with the design capacity of battery, sends alerting signal in capacity consumption during to setting value, is convenient to the instantaneously changing battery, and is simple and convenient.
