[detailed description of the invention]
Please refer to shown in Fig. 1, Fig. 1 is the schematic diagram of an embodiment of this creation Vehicular battery sensing device, and Vehicular battery sensing device comprises Vehicular battery 10, sensing device 20 and a terminal 30.One electrical generator 11 of Vehicular battery 10 and a carrier links, and it comprises an a positive pole 10A and negative pole 10B.Sensing device 20 is electrically connected Vehicular battery 10 and electrical generator 11, in order to measure the information of voltage V of Vehicular battery 10, and sends information of voltage V to terminal 30 by a wireless module 21.
Vehicular battery 10 comprises an a positive pole 10A and negative pole 10B.In general, convenient in order to allow Vehicular battery 10 replace, the positive pole 10A designed by most battery manufacture manufacturer and negative pole 10B is a metal projection, does electrically connect in order to electrical generator 11.Therefore, at the present embodiment, sensing device 20 comprises a first end 20A and one second end 20B, first end 20A and the second end 20B can be designed to a metal collar, is set in metal projection, makes sensing device 20 be electrically connected Vehicular battery 10 and electrical generator 11.In other words, when Vehicular battery end-of-life, sensing device 20 can reuse, and after only needing to be disassembled, is again set on new Vehicular battery.
Carrier can be an automobile or a motor bike.Terminal 30 can be a mobile computer or a running gear, and running gear includes but not limited to mobile phone, intelligent mobile phone, flat board or action secretary (PDA).The wireless module 21 of sensing device 20 can be the self-defining communications protocol wireless module of a wireless module (such as: WIFY) meeting IEEE802.11 communication protocol standard, a Bluetooth transmission wireless module, pole honeybee (ZigBee) wireless module or an open frequency range.Terminal 30 also has the wireless transport module 31 of wireless module 21 type of corresponding sensing device 20.
At the present embodiment, wireless module 21 and wireless transport module 31 are a Bluetooth transmission wireless module, and terminal 30 is an intelligent mobile phone.Sensing device 20 provides electric power by Vehicular battery 10, and when carrier does not start, user matches with the wireless module 21 of sensing device 20 by the wireless transport module 31 of terminal 30; After having matched, sensing device 21 measures the voltage status of Vehicular battery 10, is sent to terminal 30 after obtaining an information of voltage in the mode of Bluetooth transmission, voltage status (such as: the magnitude of voltage of current Vehicular battery 10) is shown to user and knows.
Therefore, user learns by the mode of bluetooth the voltage status that Vehicular battery 10 is current, and then utilizes computing function and the use experience of terminating set, judges the reference informations such as life-span of Vehicular battery 10 and service condition, increases traffic safety.
For more understanding this creation, coordinate with reference to shown in figure 2, Fig. 2 is the diagram of circuit of this creation Vehicular battery method for sensing one embodiment.Method for sensing comprises step S20 by the Vehicular battery of sensing device electrically connect at carrier, multiple information of voltage, S21 in order to measure Vehicular battery utilize terminal self-inductance measurement device to receive these information of voltage, S22 according to a preset rules and information of voltage, judge that carrier is a generator mode or a battery mode and the S23 User's Interface display information of voltage in terminal.
User's Interface described in the present embodiment can be user's display interface of the application program (being commonly called as APP) being arranged on intelligent mobile phone, there is a preset rules in application program, notifies user according to received information of voltage with simpler display mode.
This case has usual skill personage and known, in general, the magnitude of voltage of the Vehicular battery of automobile is greatly between 12.3 to 13.3 volts, to arrange in pairs or groups dissimilar Vehicular battery according to different automobile types, in any case, the maximum voltage value of Vehicular battery can not higher than the voltage of normal power generation machine, therefore, preset rules as described in step S22, the operation principles of above, at the present embodiment, preset rules is set with a threshold value, and threshold value is set in the magnitude of voltage (maximum voltage of large multiple generator is between 14 to 15 volts) between 14 to 15 volts.After electrical generator comes into operation (i.e. car engine), the electric power that electrical generator produces preferentially can provide the electric power on carrier needed for all loads, and to Vehicular battery charge to saturated till, therefore, the voltage that sensing device 20 measures is the generating voltage of electrical generator and the voltage of battery.
In other words, when the information of voltage of sensing device 20 measurement is once higher than threshold value (such as: 14 volts), namely represent that carrier enters a generator mode, otherwise, when carrier does not start, the magnitude of voltage of what the voltage that sensing device 20 measures was very simple is exactly Vehicular battery 10, there is no fear of exceeding threshold value (such as: 14 volts), namely, when these information of voltage are lower than a threshold value, judge that carrier is a battery mode.When these information of voltage are higher than threshold value and under being battery mode, switching carrier is a generator mode.
In addition, about about 2 years of the service life of Vehicular battery, the factor affecting battery life comprises battery erection work environment, the load state of carrier, maintenance status and discharge and recharge frequency, therefore, except recording initial installed date, record frequency of utilization also can assist the service life judging Vehicular battery.
Vehicular battery method for sensing separately comprises step: S24 utilizes these information of voltage of terminal record; And S25 is when carrier is judged as generator mode from battery mode, assert and record carrier for once to start.
This creation is except allowing user can in real time by the mode of transmission over radio, inspect outside the voltage of Vehicular battery 10, also can judge whether the Vehicular battery of carrier or electrical generator have fault or need docking, add the safety of driving by voltage collocation current operating state (such as battery mode or generator mode) measured.
In general, under the state that carrier does not start (battery mode), the voltage of Vehicular battery must 12.3 or 12.4 volts just can start carrier more smoothly, electrical generator is allowed to carry out work, therefore, the voltage below level of Vehicular battery may be that charge capacity is not enough, the aging situation that cannot charge normal or have electric leakage.
In addition, under the state that carrier starts (generator mode), the groundwork of electrical generator is the good operating voltage (such as: 14 volts) of maintenance one, but the load on carrier can cause voltage to reduce (battery do not fill full also can drag down voltage); When the load on carrier is too much, when causing the electric energy generated of electrical generator to be not enough to meet load need for electricity amount, except the generating of electrical generator itself, also can use the electric power that Vehicular battery stores, that is, when the magnitude of voltage under generator mode is too low, except load consumption is excessive, seriously cause outside electric power deficiency, but also have another kind to be, generator failure, causes generation deficiency or cannot normal power generation.Electrical power generators is not enough or normal power generation cannot will cause and cannot charge to Vehicular battery, and supplies the electricity needs (such as: headlight, engine ignition etc.) of carrier itself, seriously can affect safety.Otherwise the magnitude of voltage under generator mode is too high, the load on carrier or Vehicular battery may be endangered.
In sum, this creation is under different mode (battery mode and generator mode), information of voltage comprises a high potential warning, a normal voltage display and a low voltage warning, and it to utilize on User's Interface different colours and pictorial symbolization to point out user.The relation that information of voltage and User's Interface show is as shown in the table:
It should be noted that the voltage value in above table can have different settings according to different battery, carrier type (such as: automobile or motor bike), above-mentioned numerical value is one and illustrates and be not used to limit this creation.
Although embodiment of the present utility model discloses as mentioned above; so and be not used to limit the utility model; anyly have the knack of relevant art; not departing from spirit and scope of the present utility model; such as work as according to shape, structure, feature and the quantity described in the utility model application range and can do a little change, therefore scope of patent protection of the present utility model must be as the criterion depending on the right person of defining appended by this specification sheets.
