Fast vs. Slow Charging: Pros & Cons

To charge the battery to 100 percent using AC power takes several hours. DC fast charging can provide 80 percent charge in just around 30 minutes, but it continuously decreases the charging capacity. In some battery electric vehicles, the charging capacity is limited in order to preserve battery service life. Even small charging losses can lead to waste heat and cause a real challenge. Moreover, e-car inverters are not designed for continuous charging with very low power. So how should we deal with this? What are the limitations, and what makes financial sense? And what role does the driver's comfort and daily use play? What charging type will win in the long term for which business case? What are the actual pros and cons? Will megawatt charging be able to play on a relevant role?
