EV Charging


A nationwide expansion strategy is currently under development

Convalt Energy is currently setting up EV charging stations in New York and other domestic markets, expecting to go live in 2025. Our plan is to setup level 2 and level 3 charging stations. We expect to announce this strategy over the next few months!

A main hindrance to this growth is a lack of clear information on the economic, environmental and utility infrastructure impacts of daytime EV charging with solar. However, Convalt has designed a plan that would install the optimal solution for EV car owners and the utility supplying the electricity.


Looking to bypass current technologies, we expect to focus our efforts on next generation EV charging technologies.

EV Charger Types


Level 1 Charging

2 to 5 miles of range per
1 hour of charging

Level 1 Charging stations use a normal 120-volt connection with a standard household outlet with no installation costs. Although this typically takes place in the owner’s home, the disadvantage is a slow charging speed.

Level 1 provides 1.4 kw of power, basically a conventional wall socket, and requires no additional circuitry, aside from the adapters required to connect the EV to the socket.


Level 2 Charging

10 to 20 miles of range per
1 hour of charging

Level 2 EV chargers use a 240-volt power source (e.g., oven or clothes dryer). Charging times are much faster than level 1. Many modern houses have these outlets.

Level 2 charging normally occurs in workplaces, business locations (hotels, gas stations, private parking lots), and public locations (on-street parking spaces, garages, streets, public parking lots— wherever cars are likely to be stationary for hours at a time).


Level 3
DC Fast Charging

60 to 80 miles of range per
20 minutes of charging

Level 3 DC fast-charging devices use very high voltage and can add 90 miles of range to an EV in 30 minutes. These chargers are extremely expensive.

Regularly using Level 3 charger can ultimately hurt an EV’s battery; however, a Tesla survey found it doesn’t affect their EVs. Level 3 DC fast charging is not ideal for individual use. It is designed for public use (e.g., commercial locations).

Level 2 Charging

AC power is supplied from the charging station to the
on-board charger, which supplies DC power to the battery.


DC Fast Charging

The charger is off board the vehicle and supplies DC power directly to the battery.
