Fig. 1 is the process flow diagram of a kind of battery electricity detection method in the embodiment of the present invention.Please refer to shown in Fig. 1, below the step of battery electricity detection method is described in detail.
Step S101: detect the output voltage of battery with the fixed cycle and store.
In concrete enforcement, the described fixed cycle can carry out different settings as required, detects the output voltage of one-shot battery, then stored by the output voltage at every turn detected at interval of regular time.
In concrete enforcement, for the storage unit storing output voltage, the output voltage number that it stores can be set, such as can arrange one and store Buffer Pool, up-to-date 20 output voltages obtained of fixed storage, when detection obtains the 21st output voltage, abandon the output voltage that first of oldest stored stores, by that analogy, described storage Buffer Pool can be made thus can to store 20 up-to-date output voltages.
Step S102: when receiving the request obtaining charge value, the multiple output voltages according to up-to-date storage calculate one or more monitoring voltage.
In concrete enforcement, multiple different battery charge level can be preset, the battery electric quantity scope that each battery charge level is corresponding different, and the concrete number setting multiple output voltages that each battery charge level needs detect, be referred to herein as target voltage and detect number of times.Such as, preset 5 described battery charge level, be respectively 100% charge level level, 80% charge level level, 60% charge level level, 40% charge level level, 20% charge level level.In one embodiment, the target voltage of each battery charge level detects number of times can be identical, and it is 5 that the target voltage that such as setting each battery charge level needs to detect detects number of times.In another embodiment, the target voltage detection number of times setting each battery charge level can be different, such as supposing that the target voltage of 100% charge level level detects number of times is 3, it is 4 that the target voltage of 80% charge level level detects number of times, it is 5 that the target voltage of 60% charge level level detects number of times, it is that to detect number of times be 7 for the target voltage of 6,20% charge level level that the target voltage of 40% charge level level detects number of times.
In concrete enforcement, can attempt taking out the output voltage values that target voltage detects time several up-to-date storage in each grade successively according to fixing hierarchal order, it is corresponding with current trial grade that described target voltage detects number of times, then the output voltage values of taking-up is used for the calculating of monitoring voltage.
In one embodiment of this invention, according to battery charge level from height to low order, attempt successively taking out the output voltage values that target voltage detects time several up-to-date storage, it is corresponding with battery charge level that described target voltage detects number of times;
If attempt taking out successfully, then carry out the calculating of described monitoring voltage;
If attempt taking out unsuccessfully, then continue to detect number of times according to the target voltage that next lower battery charge level is corresponding and attempt, until travel through whole described battery charge level.
In concrete enforcement, when carrying out the calculating of described monitoring voltage, calculate the mean value that described target voltage detects the output voltage values of time several up-to-date storage, and using described mean value as described monitoring voltage.
In another embodiment of the invention, can according to the order from the paramount battery charge level of low battery charge level, attempt successively taking out the output voltage values that target voltage detects time several up-to-date storage, it is corresponding with battery charge level that described target voltage detects number of times;
If attempt taking out successfully, then carry out the calculating of described monitoring voltage;
If attempt taking out unsuccessfully, then continue to detect number of times according to the target voltage that next higher battery charge level is corresponding and attempt, until travel through whole described battery charge level.
Be described by a kind of embodiment of an example to step S102 below.
Such as, default battery charge level is 5 grades, it is 3 that the target voltage of 100% charge level level detects number of times, it is 4 that the target voltage of 80% charge level level detects number of times, it is 5 that the target voltage of 60% charge level level detects number of times, it is that to detect number of times be 7 for the target voltage of 6,20% charge level level that the target voltage of 40% charge level level detects number of times.For convenience of implementing, the storage Buffer Pool storing output voltage values can be set and can store at most 7 output voltage values.
When receiving the request obtaining charge value, which rank of in the 5 grades of battery charge level preset of unknown current battery charge, then according to the order from 100% charge level level to 20% charge level level, attempt getting described target voltage in each battery charge level successively and detect time several output voltage, if attempt taking out successfully, then carry out the calculating of monitoring voltage, if attempt taking out unsuccessfully, then continue to attempt detecting number of times according to the target voltage that next lower charge level is corresponding and take out multiple output voltage.
Suppose the output voltage values first attempting taking-up 3 up-to-date storages in 100% charge level level, if attempt taking out successfully, then carry out the calculating of described monitoring voltage; If attempt taking out unsuccessfully, such as to store in the buffer zone of output voltage values less than 3 output voltage values, then continue to attempt, until travel through whole described battery charge level, in this example because the target voltage of lower charge level detects number of times comparatively greatly, can continue to attempt.
Or, in another example, also can according to the order from 20% charge level level to 100% charge level level, attempt getting described target voltage in each battery charge level successively and detect time several output voltage, if attempt taking out successfully, then carry out the calculating of monitoring voltage, if attempt taking out unsuccessfully, then continue to attempt detecting number of times according to the target voltage that next lower charge level is corresponding and take out multiple output voltage.More specifically, suppose the output voltage values first attempting taking-up 7 up-to-date storages in 20% charge level level, if attempt taking out successfully, then carry out the calculating of described monitoring voltage; If attempt taking out unsuccessfully, such as storing less than 7 output voltage values in the buffer zone of output voltage values, then continue to attempt higher lower level, is also 40% charge level level, namely attempt the output voltage values of taking-up 6 up-to-date storages, until traversal all batteries charge level.
It is pointed out that in other embodiments of the invention, each default battery charge level is set requires that the described target voltage detection number of times detected can be identical or different, does not limit at this.
It is pointed out that in other embodiments that we are bright, the battery charge level number preset can be arranged as required, does not limit at this equally.
For making result of implementation more accurate, in one embodiment of the invention, the target voltage that the battery charge level of lower electricity is corresponding detects number of times, is greater than the target voltage detection number of times that the battery charge level of higher electricity is corresponding.Such as, the target voltage that 80% charge level level requires detects the target voltage detection number of times that number of times is greater than 100% charge level level requirement, the target voltage that 60% charge level level requires detects the target voltage detection number of times that number of times is greater than 80% charge level level requirement, by that analogy.The hypothesis of upper example just meets this set, it is 3 that the target voltage of 100% charge level level detects number of times, it is 4 that the target voltage of 80% charge level level detects number of times, it is 5 that the target voltage of 60% charge level level detects number of times, it is that to detect number of times be 7 for the target voltage of 6,20% charge level level that the target voltage of 40% charge level level detects number of times.
Step S103: determine to export battery charge level according to described one or more monitoring voltage.
In concrete enforcement, determine to export battery charge level according to the described monitoring voltage that step S102 calculates, refer to which grade from the battery charge level preset, determine that the electricity of present battery is actual is in.And each default battery charge level is provided with corresponding range of voltage values, such as: the corresponding 5V-4.5V of 100% charge level level, the corresponding 4.5V-4V of 80% charge level level, the corresponding 4V-3.5V of 80% charge level level, the corresponding 3.5V-3V of 600% charge level level, the corresponding 3V-2.5V of 40% charge level level, the corresponding 2.5V-2V of 20% charge level level.
In one embodiment of this invention, in step S102 according to from high battery charge level to the order of low battery charge level, attempt successively taking out the output voltage values that target voltage detects time several up-to-date storage, then this step S103 determines to export battery charge level, can as follows:
Judge described monitoring voltage whether within the range of voltage values corresponding to the battery charge level of current trial;
When described monitoring voltage is within the range of voltage values corresponding to the battery charge level of current trial, determine that the battery charge level of described current trial is described output battery charge level;
When described monitoring voltage is not within the range of voltage values corresponding to the battery charge level of current trial, then continue calculate described monitoring voltage according to next lower battery charge level and do to judge, until travel through whole described battery charge level.
The example continued in integrating step S102 is described.
In step s 102, suppose after described current trial grade (100% charge level level) successful experiment takes out 3 output voltage values, calculating the monitoring voltage that the mean value of 3 output voltage values obtains described current trial grade is 4.6V, then determine that described current trial grade i.e. 100% charge level level is described output battery charge level; Otherwise, suppose that the monitoring voltage that 100% charge level level calculates is 4.3V, can be determined it not at the range of voltage values 5V-4.5V that current trial grade (100% charge level level) is corresponding, then proceed the judgement of the described monitoring voltage of next lower charge level (80% charge level level), namely 4 output voltage values of the up-to-date storage attempting taking-up 80% charge level level correspondence are continued, and to calculate monitoring voltage be 4.2V, then determine that described current trial grade i.e. 80% charge level level is described output battery charge level.In another embodiment of the invention, traveled through all battery charge level and all can not determine described output battery charge level, then can show battery electric quantity too low.
It should be noted that, it will be understood by those skilled in the art in step S102 according to the order from the paramount charge level of low charge level carry out trial take out output voltage calculate time, this step S103 carries out the embodiment of the determination of described output battery charge level, does not repeat them here.
The embodiment of the present invention is by detecting the output voltage of battery with the fixed cycle and storing, when receiving the request obtaining charge value, multiple output voltage values according to up-to-date storage calculate one or more monitoring voltage, determine to export battery charge level according to described one or more monitoring voltage again, the method of single measurement output voltage is adopted compared to existing technology, the load of external circuits change or exist the situations such as undesired signal affect the change of single output voltage values time, the technical scheme of the embodiment of the present invention battery electric quantity corresponding to the output battery charge level determined according to one or more monitoring voltage, and described monitoring voltage is calculated by multiple output voltage values of up-to-date storage to obtain, thus make to detect the battery electric quantity that obtains more close to the battery dump energy of reality, and then improve the accuracy detecting battery charge level.
Further, because when battery is in lower electricity, output voltage change frequency is larger, the technical scheme of the embodiment of the present invention detects number of times by the target voltage that the battery charge level of the lower electricity of setting is corresponding, be greater than the target voltage detection number of times that the battery charge level of higher electricity is corresponding, thus the battery charge level that the described monitoring voltage calculated by multiple output voltage is determined is more accurate.

Step S201: detect the output voltage of battery with the fixed cycle and store;

In the present embodiment, step S201 with reference to the explanation of step S101 in Fig. 1 to step S103, can not repeat them here to the explanation of step 203.
In the present embodiment, can be different from description battery electric quantity when describing described output charge level, such as, describing mode is: be followed successively by one-level, secondary, three grades, level Four and Pyatyi from higher charge level to lower charge level, the corresponding 100% charge level level of one-level, the corresponding 80% charge level level of secondary, three grades of correspondence 60% charge level levels, the corresponding 40% charge level levels of level Four, the corresponding 40% charge level level of Pyatyi, so implementation step S204 is according to described output battery charge level determination battery electric quantity.Such as described output battery electric quantity is secondary, so determines that battery electric quantity is 80%.It will be appreciated by those skilled in the art that this is relevant with the form finally exporting battery electric quantity, do not repeat them here.
