Above-mentioned vane change device dispatches from the factory from produce accomplishing, and to being installed to the blower fan operation that powers on, often needs storage for a long time, transports and debugs; The decay that the electric weight of rechargeable battery can be gradually in this process, if untimely be its charging, its inner chemical composition will be ineffective gradually; Cause battery electric quantity to reduce; The life-span reduction, but in the prior art, also there is not special charging device for the charging of the rechargeable battery in the vane change device that is not fit into fan operation as yet.
The utility model content
The utility model technical problem to be solved just provides a kind of special battery charger for the charging of the rechargeable battery in the vane change device that is not fit into fan operation as yet.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of battery charger comprises the power interface that can be coupled with power supply, comprises also being the charhing unit of battery charge that this charhing unit and power interface are coupled.
Further, above-mentioned charhing unit is coupled through overvoltage protective module and/or filtration module and power interface.
Further, in charhing unit, also include temperature sensor, charhing unit is adjusted into the charging voltage of battery charge according to the temperature signal of temperature sensor collection.
Further, also comprise the indicator light that is coupled with charhing unit, described indicator light changes indication according to the charged state from charhing unit.
Further, charhing unit also is coupled through temperature relay I and power interface, and this temperature relay I is a normally opened contact, but in temperature closed its contact during more than or equal to a certain temperature; Also comprise the heater that is coupled through temperature relay II and power interface, this temperature relay II is a normally-closed contact, but breaks off its contact during more than or equal to a certain temperature value in temperature.
Further, the closed temperature of temperature relay I is 5 ℃, and the break-off signal of temperature relay II is 15 ℃.
Further, the input voltage of power interface is 220V-380V.
The beneficial effect of the utility model is:
The utility model discloses a kind of battery charger, this device can charge for the rechargeable battery that also is not installed in the vane change device that moves on the blower fan, thereby avoids the decay of battery electric quantity, prolongs its useful life.
North wind field cold weather mostly, so this battery charger can adjust charging voltage according to temperature, guarantees charging effect, and this device also includes heater, and the working temperature of assurance device is not less than 5 ℃, prolongs its useful life.
Be difficult in the wind field find stable high voltage source, so the input voltage of this battery charger elects 220V-380V as, its highly versatile conveniently uses in wind field.
