Embodiment Construction
[0010] Such as figure 1 As shown, the input terminal of the power module is connected to the power supply input, and its output terminal is connected to the controllable switches K1 and K2 in parallel with the port of the charging gun. The auxiliary power supply has two power-taking terminals, one of which is connected to the power supply input through the transformer T1, and the other power-taking terminal is connected to the port of the charging gun. The output terminals of the auxiliary power supply are respectively connected to the control system, the payment system and the electronic lock of the charging pile to supply power for the control system, the payment system and the electronic lock of the charging pile. The control system controls the payment system. The control system is connected with a power failure monitoring device for monitoring whether the power input is powered off, wherein the power failure monitoring device includes a voltage detection circuit and a fr...

The invention relates to a charging pile, in particular to a charging pile with a power failure processing function. The charging pile comprises a power module, a charging gun port, a control system and an auxiliary power supply, wherein the power module converts power supply input and then charges a battery pack of an electric vehicle through the charging gun port; the auxiliary power supply is used for taking electricity to supply to the control system; and the auxiliary power supply takes electricity from the charging gun port. When the power supply input is powered off in the charging process, the auxiliary power supply takes electricity from the battery pack of the electric vehicle through the charging gun port, so that the auxiliary power supply can also supply electricity to the control system to ensure that the control system can further work.
Description
technical field [0001] The invention relates to a charging pile, in particular to a charging pile with a power-off processing function. Background technique [0002] When the electric vehicle is to be charged, the charging cable needs to be inserted into the charging port of the electric vehicle. When the control system of the charger confirms that the electric vehicle is connected, and the user completes the setting of charging power and payment through the human-computer interface, the control system of the charger will open the electronic lock and lock the charging port of the charger and the electric vehicle. To avoid the charging gun falling off during charging. When the charging is completed, the control system of the charger unlocks the electronic lock, and the user can normally pull out the charging gun after unlocking. [0003] The auxiliary power supply supplies power to the control system of the charger after taking power from the power input. When the power in...
