Is Tesla charging pile in Winbond Hotel charging fast?

The Tesla charging pile of Winbond Hotel charges quickly, and Tesla's super charging pile can be filled in about an hour and a half.

Take Tesla Model S75D as an example, its charging time in Tesla super charging pile is acceptable, because the super charging pile uses 380V DC, which can greatly shorten the charging time. Using the super charging station, it can be filled in half in 20 minutes and in 80 minutes, driving more than 400 kilometers.

However, most Tesla owners will install a single-phase wall charger in the garage or parking space, using 220V AC. This charging method takes a long time, and it can charge 6-7 kWh in one hour, about 40 kilometers. It takes about 10 hour to charge slowly.

Charging technology of charging pile

According to the different energy conversion modes of electric vehicle battery charging, charging devices can be divided into contact type and induction type. With the rapid development of power electronics technology and converter control technology, as well as the maturity and popularization of high-precision controllable converter technology, the constant voltage and current-limiting charging mode with continuous changes of charging current and charging voltage has basically replaced the phased constant current charging mode.

The charging process is still dominated by constant voltage and current limiting charging mode. The biggest problem of contact charging is safety and universality. In order to meet the strict safety charging standards, many measures must be taken in the circuit to make the charging equipment charge safely in various environments. Constant voltage current limiting charging and phased constant current charging belong to contact charging technology.
