具体实施方式 Detailed ways

[0019] 为了缩短充电时间,必须进行快速充电,要实现快速充电必须提高充电功率,要提高充电功率必须要有大功率的充电器,传统的大功率充电器是在输出电压不变的前提下增大输出电流,增大输出电流会受到充电接口、充电连线等器件所允许的最大电流的限制,因此用增大输出电流的方法来提高充电器的输出功率受到很大的限制,本专利提出了用增大输出电压的方法来提高充电器的输出功率,同时充电器能和智能终端握手通讯,根据智能终端所发的指令来调节输出电压,最大程度地满足智能终端快速充电的需求。 [0019] In order to shorten the charging time, the need for fast charging, fast charging to the charging power must be increased to improve the charging power must have a high power charger, the charger is a traditional high-power output voltage constant premise to increase the output current, the output current to increase the maximum current is limited to a charging port, charging connections allowed by other devices, and therefore a method to increase the output current to increase the output power of the charger is greatly limited, this patent proposed a method of increasing the output voltage to increase the output power of the charger, and the charger and can handshake communication intelligent terminal, the output voltage is adjusted in accordance with instructions issued by the smart terminal, to best meet the needs of rapid charging intelligent terminal. 因此,本发明提供一种能够缩短充电时间的智能可变换输出电压的充电器和充电方法。 Accordingly, the present invention provides a smart charging time can be shortened conversion output voltage charger and a charging method.

[0020] 本发明就是在保障供电电流在通用接口器件、充电电源连线等器件所允许的范围之内用提1¾充电器输出电压的方法来提1¾充电器的输出功率。 [0020] In the method of the present invention is to guarantee the power supply current in a range of common interface devices, charging devices such as power connections allowed only mention 1¾ charger output voltage to provide the output power 1¾ charger.

[0021] 充电器的输出功率公式为:P = UXI [0021] The charger output power formula: P = UXI

[0022] 其中P为充电器的输出功率、U为输出电压、I为输出电流。 [0022] wherein P is the output power of the charger, U is the output voltage, I is the output current.

[0023] 从以上公式可看出,在充电器输出电流I不变的情况下,其输出功率P随输出电压U的提高而成比例提高。 [0023] As can be seen from the above equation, in the case of the charger output current I is constant, the output voltage U with the output power P increases in proportion to the increase. 因此本发明在保持输出电流稳定的情况下提高输出电压,从而加快充电。 The present invention thus increasing the output voltage while maintaining a stable output current, thus speeding up the charge.
