Can I install a DC charger in the home?
No is the simplest answer.
DC quick chargers can be used in both commercial and industrial environments. This is due to the high power consumption and high costs of Level 3 chargers.
To operate, Level 3 fast chargers need 440 volts DC power. These power requirements are not met by most residential properties. Charging units at such high power levels is dangerous for most homes.
The high price of DC fast chargers prevents them from being installed at home. A DC rapid charger can cost over $50,000 to purchase and operate. This is due to the complexity and cost of installation and maintenance.
