Abstract
The utility model relates to a device for displaying the power information of a battery in real time, which belongs to the technical field of a power supply of electrical equipment so as to solve the problem that traditional electronic equipment cannot identify the battery model so that the power information of the battery cannot be checked. The device comprises a battery information identification circuit; and both ends of the battery information identification circuit are respectively connected with the battery and the host information port of the electronic equipment so as to display the power information of the battery on the electronic equipment. The device for displaying the power information of the battery in real time can be used for the electronic equipment with the power supplied by the rechargeable battery, not only can detect the model of the battery but also can display the power information of the battery.
Description
Technical field
The utility model relates to a kind of device of real-time demonstration battery electric quantity information, belongs to consumer power supply technique field.
Background technology
A lot of portable electric appts as mobile phone, PDA, digital camera etc., all adopt rechargeable battery as its power-supply unit.At present, the battery that a lot of models are arranged on the market can be general on the electronic equipment of many moneys model.But because the difference of battery size, make the electronic equipment can not be, cause as checking that functions such as battery electric quantity information can not use fully to discerning for the battery size of its power supply.
The utility model content
Can not check the problem of battery electric quantity information for solving existing electronic equipment because of not discerning battery size, the utility model proposes a kind of device of real-time demonstration battery electric quantity information, this device comprises the battery information identification circuit, the two ends of described battery information identification circuit are connected with the host information port of battery and electronic equipment respectively, are used for showing on electronic equipment the information about power of battery.
Thereby the utility model identifies battery information by being connected with the internal port of electronic equipment, not only can detect the model of battery, can also show battery electric quantity information.
Description of drawings
Fig. 1 structural representation that to be the utility model be connected with electronic equipment with battery.
Embodiment
Embodiment of the present utility model has proposed a kind of device of real-time demonstration battery electric quantity information, present embodiment with the application of device in digital camera of this real-time demonstration battery electric quantity information as an illustration, as shown in Figure 1, this device is made up of the battery information identification circuit, the two ends of described battery information identification circuit are connected with the host information port of battery and electronic equipment respectively, are used for showing on electronic equipment the information about power of battery.
When battery used in digital camera, P+ and P-port were used to digital camera that the start operating voltage is provided, and C port and TO SYSTEM1, TO SYSTEM2 port are connected with the digital camera internal port, identify battery information thereby move it to low level.At last the battery information that identifies is sent to digital camera inside, be used for showing in real time battery electric quantity information by this device.
Further, this device can also comprise charge protector, over circuit and circuit overcurrent protection, as shown in Figure 1, when battery is in charging process, the CO pin of the main control chip U1 of this device (can adopt the R5460 chip) is in noble potential, the first switching tube U2A is in closure state, form charge circuit, when main control chip U1 detects battery and is full of, the CO pin of main control chip U1 transfers electronegative potential to by noble potential, and this moment, the first switching tube U2A disconnected, because charge circuit is cut off, battery enters the additives for overcharge protection state, thereby realizes additives for overcharge protection; When battery is in discharge process; the DO pin of the main control chip U1 of this device is in high level; second switch pipe U2B is in closure state; form discharge loop, when main control chip U1 detected battery electric quantity less than threshold values, the DO pin of main control chip U1 transferred low level to; this moment, second switch pipe U2B disconnected; because discharge loop is cut off, battery enters the over state, thereby realizes over.
And; in discharge process; as shown in Figure 1; when the voltage that detects VM end as the main control chip U1 of this device surpasses predetermined discharge over-current and detects voltage, and time of this state continuance when surpassing predetermined discharge over-current and detecting time delay, the DO terminal of main control chip U1 transfers electronegative potential to; this moment, second switch pipe U2B disconnected; because discharge loop is cut off, battery enters the overcurrent protection state, thereby realizes overcurrent protection.
In addition, when battery is in the additives for overcharge protection state, as shown in Figure 1, if the main control chip U1 of this device detects the voltage of vdd terminal and is lower than and overcharges threshold values, then should discharge overcharge condition, make battery can continue charging, this moment, the CO pin of main control chip U1 transferred noble potential to, the first switching tube U2A transfers closure state to, forms charge circuit, thereby realizes overcharging release; When battery is in the over state procedure; the voltage that detects vdd terminal as the main control chip U1 of this device was higher than when putting threshold values; should discharge over-discharge state; make battery can continue discharge; this moment, the DO pin of main control chip U1 transferred noble potential to; second switch pipe U2B transfers closure state to, forms discharge loop, thereby realizes that overdischarge discharges.
This embodiment not only can show the information about power of battery, can also protect the overcharging of battery, overdischarge and excess current.
The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
