Problems solved by technology
Even in the actual use of AC (DC) charging equipment, there will inevitably be uneven distribution of customer usage rates in different locations and different time periods. When not in use, if the entire charging equipment is always powered on In the working state, the power consumed by the standby and no-load is generally in the range of tens of watts to hundreds of watts, and some DC high-power charging equipment is even higher.
In the period when electric vehicles are not popularized, the utilization rate of customers is very low, and the accumulation value of no-load loss will increase with time. This part of electric energy is not only wasted in vain, but also increases the cost of use and reduces the service life of the equipment.

The invention discloses charging equipment with switching and energy-saving functions and a switching and energy-saving method for the charging equipment. The standby power of high-power charging equipment is reduced by detecting ambient light, a proximity sensor and a load current. By the charging equipment and the method, the working standby electric energy waste of a high-power charging power supply of alternating-current and direct-current charging equipment during a using process is overcome. The power supply of the charging equipment is divided into two parts, namely a low-power consumption standby power supply and the high-power charging power supply, wherein the standby power supply is the power supply for supplying power to weak-current components of the detection and control parts of the charging equipment, and the standby static power consumption of the standby power supply is only hundreds of milliwatts; and the standby power supply of the charging equipment also can be directly started by an upper computer, so that the standby power supply reenters a standby working state to prepare to start a charging power supply module for charging a load.
Description
technical field [0001] The invention relates to a charging device for an electric vehicle, in particular to a charging device with switching and energy-saving functions and a switching and energy-saving method thereof. Background technique [0002] General AC (DC) charging equipment can complete the basic AC (DC) charging function, and does not adopt power-saving measures to reduce the standby power consumption of the main circuit. In order to adapt to the promotion and application of electric vehicles from less to more, charging equipment The usage rate will also inevitably go from low to high. Even in the actual use of AC (DC) charging equipment, there will inevitably be uneven distribution of customer usage rates in different locations and different time periods. When not in use, if the entire charging equipment is always powered on In the working state, the power consumed by the standby and no-load is generally in the range of tens of watts to hundreds of watts, and som...
