EVSE (Electric Vehicle Supply Equipment)

It appears the major obstacle to the mass adoption of electric vehicles is the perceived issue of range anxiety. This is the feeling that the EV battery would run out of capacity before reaching a recharging station. There are approximately 115,000 gas stations in the U.S., of which an estimated 65,000 have a convenience store. The industry believes each station has a least 8 pumps or a minimum of 920,000 fill ports allowing for an average filling time of less than 15 minutes for standard ICE vehicles.

There are three typical EV chargers:

Level 1 operates at 120VAC (16amps, 1.9kW, up to 5miles/hour of driving range)
Level 2 operates at 240VAC (32amps, 7.6kW, up to 32miles/hour of driving range)
DCFC (Direct Current Fast Charge) has three levels
- A) Up to 50kW designed to add at least 42 miles of driving range in 15 minutes
- B) Up to 150kW designed to add at least 125 miles of driving range in 15 minutes
- C) Up to 350kW designed to add 300 miles of driving range in 15 minutes.

All recharge rates depend on the electrical specifics of the charging grid circuit and the vehicle's battery type, and its charging circuit.

Many drivers expect the same business model for BEVs as with ICE vehicles - which is not possible using the majority of the existing 120,000 EV charging ports, most of which are Level 2 chargers with less than half being some level of DCFC. The great news is that the new infrastructure bill includes 7.6 billion dollars to invest in EV charging infrastructure, and most will be DCFC solutions. Many power companies are also funding various EVSE projects,

which are also designed to be DCFC.

We can all help society reach a "net-zero transportation" goal while decreasing our operating costs by purchasing and using electric vehicles recharging using your own distributed Solar PV or another renewable energy source. Keep in mind the newer EV's will have the capability to use itself

as your home or business battery storage system when coupled with a

charging station that allows for V2G/V2H (vehicle to grid/vehicle to home) service avoiding disruption during a power outage or planned curtailment.

Only a handful of companies have recognized the issues associated with the interconnection of DCFC's onto the grid and what that impact will have. Many electricity providers have shown during EV charger site audit's the local grid can't support the needed load for multiple DCFC charging ports without major grid upgrades. A few companies have invented a unique solution that incorporates a compact hybrid battery solution that allows the grid load to be similar to a standard 208/240VAC Level 2 charger. These unique solutions utilize the stored battery energy to act as a buffer allowing for DC Fast Charging for multiple vehicles, up to the battery capacity. These standard products eliminate the need to provide expensive grid updates, special permitting, allowing anyone to replace an existing Level 2 charger with a DCFC while being immune to time of use (TOU) and demand charges.

The 3E Enterprise Group can assist in designing, procuring, installing, and maintaining your individual or fleet EV charging solution. It can seamlessly include a solar and/or solar plus storage system creating a proper "net-zero transportation" solution affording you or your company

a self-consumptive zero emission lifestyle.
