Specific embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
In order that those skilled in the art more fully understand the present invention program, below in conjunction with the embodiment of the present invention
Accompanying drawing, is clearly and completely described to the technical scheme in the embodiment of the present invention, it is clear that described embodiment is only
The embodiment of a part of the invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill people
The every other embodiment that member is obtained under the premise of creative work is not made, should all belong to the model of present invention protection
Enclose.
It should be noted that term " first ", " in description and claims of this specification and above-mentioned accompanying drawing
Two " it is etc. for distinguishing similar object, without for describing specific order or precedence.It should be appreciated that so using
Data can exchange in the appropriate case, so as to embodiments of the invention described herein.Additionally, term " including " and " tool
Have " and their any deformation, it is intended that covering is non-exclusive to be included, for example, containing series of steps or unit
Process, method, system, product or equipment are not necessarily limited to those steps clearly listed or unit, but may include without clear
It is listing to Chu or for these processes, method, product or other intrinsic steps of equipment or unit.
The embodiment of the invention provides a kind of power output method of battery.Alternatively, the power output method of the battery
Can be used for controlling the power output of on-vehicle fuel.Fig. 1 is the power output method of battery according to embodiments of the present invention
Flow chart.As shown in figure 1, the power output method of the battery includes that step is as follows:
Step S102, obtains the target output of battery.
Step S104, calculates the permission power output of battery.
Whether step S106, judge to allow power output more than or equal to target output.If it is judged that allowing output
Power is more than or equal to target output, then perform step S108, if it is judged that allowing power output to be less than target output work
Rate, then perform step S102.
Step S108, power output is carried out according to target output.
The target output of acquisition can be the power output of the entire car controller from automobile.Battery allow output
Power is the power output being calculated according to the current operation conditions of battery.If the current permission power output of battery is small
The longevity of battery will be shortened in target output, and when forcing battery to be exported according to larger target output
Life, therefore, it is determined that before the power output of battery, judging to allow whether power output is more than or equal to target output, such as
Fruit allows power output more than target output is equal to, then power output is carried out according to target output, to meet vehicle
Driving requirement;If allowing power output to be less than target output, target output is reacquired, to avoid output
The shortening of battery life caused by larger power, sets the damage of battery.
By above-described embodiment, when battery carries out power output under dynamic loading conditions, output is allowed according to battery
Power and target output determine the final power output of battery, when target output exceedes allows power output, drop
Low target power output, exports, that is to say, that the final power output of battery has electricity rather than battery is forced according to target power
The intervention in pond ensures the stability of the power output of battery, it is to avoid battery overload is exported, and is led by overload output so as to avoid
The shorter battery life of cause, solves shorter battery life caused by battery power output under dynamic loading in the prior art
Problem, reached extension battery service life effect.
Alternatively, reacquiring target output includes:Send the request for reducing target output;Receiving response please
The target output after being reduced is sought, so that the target output after reducing is less than or equal to permission power output;And
Using the target output after reduction as the target output for reacquiring.
When target output is more than power output is allowed, the request for reducing target output is sent so that vehicle
Controller adjusts target output so that target output utilizes the mesh after reducing less than or equal to permission power output
Mark power output carries out power output.When target output is more than power output is allowed, entire car controller is according to vehicle
It is required that adjustment target output so that the target output of adjustment can not only support vehicles normally run, additionally it is possible to make
The power output for obtaining battery is not more than permission power output, it is ensured that battery is not in the phenomenon of overload output, so as to solve
In the prior art battery under dynamic loading power overload output caused by shorter battery life problem, reached extension electricity
The effect of the service life in pond.

Average voltage level.Warning output power is calculated according to average voltage level and minimum monolithic voltage value.
It is defeated alarm to be calculated with reference to monolithic voltage value minimum in the average voltage level and multiple monolithic voltage values of battery
Go out power, when the power of output is no more than warning output voltage, the problem of monolithic superpressure would not also occur, that is, avoid battery
Monolithic superpressure and shorten the problem of battery life, so as to solve the overload of the power under dynamic loading of battery in the prior art
The problem of shorter battery life caused by output, has reached the effect of the service life of extension battery.
By above-described embodiment, target output is adjusted according to permission power output so that target output is small
In equal to allowing power output, it is to avoid cell output overload and shorten the problem of battery life, further, since with reference to report
Alert power output adjusts the power output of battery, and the problem of battery life is shortened so as to avoid the monolithic superpressure of battery, enters
And reached the effect of extension battery life.
