Technical realization of charging pile
As the energy supply device of electric vehicle, the charging performance of electric vehicle charging pile is related to the service life and charging time of battery pack. This is also one of the most concerned aspects for consumers before buying electric vehicles. Realizing fast, efficient, safe and reasonable power supply to power battery is the basic principle of electric vehicle charger design.
In addition, the applicability of the charger to various power batteries should be considered. Intelligent variable pulse charging mode is adopted, that is, charging current pulses are adopted, including charging pulse T 1 intermittent pulse T2 and discharging pulse T3. The charger scheme of the ground charging station is that a rectifier converts the input alternating current into direct current.
And a power converter capable of adjusting DC power. Insert the plug with wire into the matching socket on the electric vehicle and input DC power into the battery for charging. The charger is equipped with a locking lever, which is convenient for the plug to be inserted and pulled out. The lever can also provide a signal to confirm that it has been locked to ensure safety.
