For example, the power supply of current-collecting device comprises first power supply and second source, and current-collecting device adopts the 1+1 backup mode, and promptly first power supply can be regarded as the stand-by power supply of second source, and second source also can be regarded as the stand-by power supply of first power supply.The maximum power that first power supply and second source can provide is 400 watts, and generally the power of current-collecting device needs is 200 watts.At first open first power supply, making first power supply is the current-collecting device power supply, in the first power supply normal work period, the efficient of the power supply of current-collecting device (ratio of the required power of current-collecting device and the power supply maximum power that can provide just) is 200 watts/400 watts=50%.When first power supply breaks down, in the time of can't powering for current-collecting device, make battery enter power supply state and temporarily be the current-collecting device power supply, and the control second source is opened, after second source is opened successfully, use second source to power as current-collecting device, during the second source power supply, the efficient of the power supply of current-collecting device also is 200 watts/400 watts=50%.
First power supply, second source and battery are connected in parallel.When opening first power supply, battery is also opened, the output voltage of battery can be arranged to output voltage less than first power supply, like this, first power supply will output current, and battery can output current, in fact is equivalent to when first power supply is the current-collecting device power supply, battery for the current-collecting device power supply, not that is to say that battery does not enter power supply state.If first power supply breaks down, the output voltage of first power supply becomes less than the output voltage of battery, and battery for the current-collecting device power supply, that is to say that battery has entered power supply state automatically like this.Because battery is in opening always,, thereby guarantee that the data in the current-collecting device do not lose so when first power supply broke down, can replace first power supply immediately was the current-collecting device power supply.
When first power supply broke down, the control second source was opened.Be in closed condition before the second source, the control second source is opened and is needed the regular hour, and after second source was opened successfully, the output voltage of second source was greater than the output voltage of battery, battery no longer is the current-collecting device power supply like this, and second source begins to be the current-collecting device power supply.
Adopt above-mentioned supply power mode, when any one power supply breaks down, use battery temporarily to power, can guarantee that like this data in the current-collecting device do not lose, open again subsequently that another does not break down can normal power supply stand-by power supply be the current-collecting device power supply.Like this, in the most of the time of current-collecting device operation, being equivalent to have only a power supply is the current-collecting device power supply, and the efficient of the power supply of current-collecting device can remain on 50%, compare for the mode of current-collecting device power supply simultaneously with two power supplys in the prior art, improved the efficient of power supply.
