In the present embodiment, the electric parameter includes at least remaining capacity, and the power-supply controller of electric 321 is also used to basis The battery dump energy that the communication terminal 331 is got determines the battery that effective power supply state is in the battery component 20 21 total surplus electricity.

In the first embodiment, the power-supply controller of electric 321 is getting all batteries 21 of the battery component 20 When current residual electricity, determine that all batteries 21 are currently in effective power supply state, and by the remaining capacity of all batteries it Be determined as the total surplus electricity.And/or any of the battery component 20 is having not been obtained in the power-supply controller of electric 321 When the current residual electricity of battery 21, determine that all batteries 21 are currently in invalid power supply state, and determine the total surplus Electricity is zero.

In another embodiment, the electric parameter further includes operating current, and the power-supply controller of electric 321 is having not been obtained To the current residual electricity of the percentage of batteries 21 of the battery component 20, and the operating current of the battery 21 currently got occurs When the rise saltus step of the first prearranged multiple, determine that the percentage of batteries 21 that current residual electricity is not acquired is in invalid power supply shape State determines that other batteries 21 are in effective power supply state, and the sum of remaining capacity of all batteries 21 currently got is true It is set to the total surplus electricity.

And/or the power-supply controller of electric 321 is in the current residual for the percentage of batteries 21 that the battery component 20 has not been obtained Electricity, and when the rise saltus step of the first prearranged multiple does not occur for the operating current of each battery 21 currently got, it determines All batteries 21 of the battery component 20 are currently in effective power supply state, and estimate the current surplus of the percentage of batteries 21 Remaining electricity, and the current residual electricity of the percentage of batteries 21 of estimation and the residue of each battery 21 currently got is electric The sum of amount is determined as the total surplus electricity.

In another embodiment, the battery component 20 includes two batteries 21, and first prearranged multiple is 1.5 again.

In another embodiment, the electric parameter further includes total charge capacity, and the power-supply controller of electric 321 exists When estimating the current residual electricity of the percentage of batteries 21, the remaining capacity for the percentage of batteries 21 that previous moment is got It is determined as the current surplus of the percentage of batteries 21 with the difference of the second prearranged multiple of total charge capacity of the percentage of batteries 21 Remaining electricity.Wherein, second prearranged multiple can be set to 1 percent times.

In the present embodiment, the electric parameter further includes total charge capacity, and the power-supply controller of electric 321 is also according to acquisition To total charge capacity of each battery 21 calculate the sum of total charge capacities of all batteries 21, and according to the total surplus The sum of electricity and total charge capacity calculate the total surplus electricity and total charge capacity of the battery component 20 The sum of ratio.

In the present embodiment, the mobile platform 30 further includes aobvious with the electricity of the power-supply controller of electric 321 communication connection Show that the ratio is transferred to the progress of electricity display unit 36 electricity and shown by unit 36, the power-supply controller of electric 321.

In this way, when the battery component 20 is abnormal in the process of running, such as between the mobile platform 30 When communication abnormality or battery itself are abnormal, the mobile platform 30 can make intelligent power estimation in time, so as to The remaining capacity situation of the battery component 20 is effectively monitored, to prompt operator to make correctly operation decision in time. For example, when 20 not enough power supply of battery component, can prompt to operate for using unmanned vehicle as the mobile platform 30 The unmanned vehicle is landed and is shut down in time by person, to prevent the unmanned vehicle because of 20 electricity shortage of battery component Caused by aviation accident generation.

Figure 10 is the flow chart of the electric quantity controlling method of the mobile platform of the embodiment of the present invention.The electricity of the mobile platform Control method can be applied in above-mentioned mobile platform.

Step 1001, the power-supply controller of electric 321 judges whether the battery of the battery component 20 is abnormal.In the present embodiment In, for ease of description, to be illustrated for including the battery component 20 of two batteries 21.The exception includes, but are not limited to The power-supply controller of electric 321 can not obtain the electricity of the battery 21, such as: the battery 21 and the power-supply controller of electric 321 Between 21 failure of communication abnormality or the battery.When two pieces of batteries 21 do not occur abnormal, 1002 are entered step, if its In one piece of appearance it is abnormal, enter step 1003, if exception occur in two pieces of batteries, enter step 1007.

Step 1002, it is two pieces of batteries that the power-supply controller of electric 321, which calculates the total electricity percentage of the battery component 20, Remaining capacity and with two pieces of batteries completely fill capacity and ratio.

Step 1003, when one of battery exception, the electric current of normal battery is obtained.

Step 1004, the power-supply controller of electric 321 judge the electric current of the normal battery whether have prearranged multiple (example: 1.5 times) jump.When there are the jump of prearranged multiple, 1005 are entered step, if it is not, then entering step 1006.

Step 1005, it is normal battery that the power-supply controller of electric 321, which calculates the total electricity percentage of the battery component 20, Remaining capacity and two pieces of batteries completely fill capacity and ratio.

Step 1006, it is two pieces of batteries that the power-supply controller of electric 321, which calculates the total electricity percentage of the battery component 20, Remaining capacity and with two pieces of batteries completely fill capacity and ratio.Wherein, the residual capacity of abnormal battery is existed with the exception battery On the basis of abnormal preceding residual capacity, come by certain depletion rate (for example, percentage per second for reducing its design capacity) in terms of Calculate the current remaining capacity of the exception battery.

Step 1007, if two pieces of batteries all communication abnormalities, judge that the battery component 20 for invalid energized state, enters Step 1008, it is zero that the power-supply controller of electric 321, which calculates the total electricity percentage,.

In the present embodiment, the mobile platform 30 is multiplexed using power switch bus and communication line, to save connection Device terminal.It is described in detail below by specific embodiment.

Fig. 7 and Figure 11 is please referred to, is that the connection structure of battery 21 provided in an embodiment of the present invention and mobile platform 30 is illustrated Figure.Wherein, the power button 35 is distinguished by multiple batteries 21 that the communication terminal 331 includes with the battery component 20 Connection.
