Any and all combinations.
The embodiment of the present application provides a kind of method for extending the charging module service life, and charging module includes fan, such as Fig. 1 institute
Show, method includes:
Step 102, the environment temperature and output power for obtaining charging module；
Wherein, environment temperature can be the temperature that charging module internal temperature sensor acquires in real time, be also possible to charge
The temperature of Modular surface or the temperature on the coupled capacitor surface inside charging module, herein with no restriction.Output power refers to
Be power that charging module exports external equipment.
Specifically, it can use temperature sensor acquisition environment temperature, utilize ammeter, voltmeter or power meter measures
Output power.
Step 104, the remaining life that charging module is predicted according to environment temperature and output power；
Wherein, there are mapping relations between environment temperature and the remaining life of output power and charging module, when environment temperature
Degree is higher, and output power power is bigger, and the remaining life of charging module is shorter.
Specifically, by many experiments, multiple groups real data is acquired, every group of data include three elements: environment temperature, defeated
Power and remaining life out.Function Fitting is carried out for three elements, to obtain environment temperature and output power and charging mould
Mapping relations between the remaining life of block.When known environment temperature and output power, the function of fitting is substituted into, can predict and fill
The service life of electric module.Further, it is also possible to the form that multiple groups real data is tabulating, environment temperature, output power and residue
Service life, three are mapped, and when known environment temperature and output power, by enquiry form, obtain corresponding remaining life.
Step 106, when remaining life is higher than lifetime threshold, fan executes the first revolving speed strategy, and the first revolving speed strategy is
The revolving speed that fan is arranged is the first revolving speed, the first revolving speed and environment temperature and output power is in mapping relations；
Wherein, lifetime threshold refers to the comparative lifetime parameter according to the projected life setting of charging module when factory, example
Such as, which can be the 10% of projected life, and 15%, 20%, 25%, 30%, 35%, it is above-mentioned to enumerate ratio only
For illustrating there is a possibility that for lifetime threshold, the actual set of lifetime threshold is not restricted, lifetime threshold can be by engineering
Teacher is according to actual demand, sets itself.First revolving speed strategy refers to setting the revolving speed of fan as the first revolving speed, wherein the
One revolving speed not instead of fixed value executes the first revolving speed according to current environment temperature and output power into adaptive adjustment
There are mapping relations for the revolving speed of strategy, environment temperature and output power and fan.
Specifically, when remaining life is equal to or higher than lifetime threshold, then it represents that lasting a long time for current charging module does not reach
To the state of service life early warning.It controls fan and executes the first revolving speed strategy, for example, environment temperature T1, output power W1,
Corresponding the first revolving speed of fan value N r/min；When environment temperature or output power increase, corresponding rotation speed of the fan becomes faster,
When environment temperature and output power reduces, and corresponding rotation speed of the fan is slack-off, and when environment temperature and output power is one of increases,
Another reduce, then corresponding rotation speed of the fan according to the revolving speed of environment temperature and output power and fan there are mapping relations into
Row calculates.
Step 108, when remaining life is lower than lifetime threshold, fan executes the second revolving speed strategy, and the second revolving speed strategy is
