The battery energy-saving circuit is a switching circuit including a semiconductor device and a resistor, and input and output terminals of the switching circuit are respectively connected with the battery body and the battery protective circuit. The battery energy-saving circuit cuts off the electricity supplied to the protective circuit by the battery body under the non-use conditions such as the storage of the battery module, and reduces the consumption of battery electricity used by the battery protective circuit inside the battery module.
Description
[technical field]
The utility model relates to a kind of battery modules, particularly a kind of energy-conservation battery modules.
[background technology]
Modern society is along with the electronic information technology develop rapidly, and the electronic equipment of various functions has obtained extensive use on the one hand; The a large amount of electric energy of application need consumption of one side electronic equipment.Present energy growing tension, thus, energy-conservation research and development at electronic equipment with use in increasing important more.Battery modules is the indispensable power supply of a lot of electronic equipments, considers the protection to battery, and existing battery modules generally comprises battery body, battery protecting circuit.Because battery protecting circuit directly links to each other with battery body, protective circuit need expend certain electric weight.Especially before the electronic equipment shipment, battery generally only is filled with about 50% of normal electric weight, when owing to transportation, the storage of electronic equipment, be easy to cause the mistake of battery to put when sale waited long storage time, thereby influences the quality and the useful life of battery.Be necessary to propose the energy-conservation battery modules of a kind of energy in fact for this reason.
[summary of the invention]
Main purpose of the present utility model is to provide a kind of energy-conservation battery modules, can reduce battery modules self power consumption.
In order to achieve the above object, the utility model provides a kind of energy-conservation battery modules, and this battery modules reduces the consumption of internal circuit to battery electric quantity when non-working condition such as depositing.This battery modules also is provided with the battery energy-saving circuit except that comprising battery body, battery protecting circuit.Described battery energy-saving circuit is the switching circuit that comprises that semiconductor device and a resistance are formed, and the input of described switching circuit, output connect battery body, battery protecting circuit respectively.When battery modules is blocked the power supply of battery body to protective circuit when non-working condition such as depositing, thereby reduce the electric quantity consumption of protective circuit to battery, causing when avoiding the long period to be in non-working condition that battery is crossed to put influences battery quality and useful life.
Compared to prior art, the energy-conservation battery modules of the utility model has reduced when battery modules is deposited internal circuit to the consumption of battery electric quantity, the mistake that has caused when having reduced the battery long term storage is put phenomenon, has guaranteed the quality of battery to a certain extent, increases the service life.
