Description

Electric vehicle charger with charging time control function
Technical Field
The invention relates to the technical field of chargers, in particular to an electric vehicle charger with charging time control function.
Background
The electric vehicle becomes an indispensable vehicle in daily life, and the characteristics of lightness and quickness are favored by the majority of users. In the charging process of the electric vehicle, the long-time charging condition often easily occurs, and under the long-time charging condition, the internal temperature of the charger can be greatly increased, so that the explosion condition of the charger is easily caused. In this regard, the prior art does not have an effective countermeasure.
Disclosure of Invention
In view of the problems in the prior art, the invention provides an electric vehicle charger with charging time control, which can control the charging time of the charger, so that the explosion condition caused by long-time charging can be avoided.
In order to achieve the above object, the present invention provides an electric vehicle charger with charging time control, comprising a charger, an electronic transfer switch, a processor, a current detection module and a timer;
the input end of the electronic change-over switch is connected with the plug through a cable, one output end of the electronic change-over switch is connected with the input end of the charger, the output end of the charger is connected with the input end of the vehicle-mounted storage battery pack through a cable, and the other output end of the electronic change-over switch is in no-load state;
the current detection module is arranged on a cable between the electronic change-over switch and the plug, a signal wire of the current detection module is connected with an input end of the processor, and the processor is also connected with the timer and a control end of the electronic change-over switch respectively.
Preferably, the processor is of the model STM32F103CBT 6.
Preferably, the plug is a two-phase plug or a three-phase plug.
The invention can detect whether the current exists or not when the current detection module is connected with a power supply in a plug-in mode, sends a current signal to the processor under the condition of the current, the processor controls the timer to start timing after receiving the signal, meanwhile, the electronic switch is communicated with the plug and the charger to charge the vehicle-mounted storage battery pack, when the timing time reaches, an overtime electric signal is fed back to the processor, and the processor controls the electronic switch to be switched to a no-load end after receiving the signal, so that the charging of the vehicle-mounted storage battery pack is automatically cut off. The charger can control the charging time of the charger, thereby avoiding the explosion condition caused by long-time charging.
