HOME ENERGY & EV CHARGING · DESIGNED FOR WHAT COMES NEXT
Beyond Level 2:
the next generation of home EV charging.
Before you install another Level 2 charger, understand what is possible now.
DOSHI helps homeowners design faster, smarter EV charging that can work with battery storage, solar, backup power, intelligent load management and emerging vehicle-to-home technology.
THE QUESTION TO ASK FIRST
Is Level 2 really the best home charging system to install today?
Sometimes, yes. But the charger is no longer the whole decision.
A home charging project can affect electrical service capacity, future charging speed, solar, battery storage, backup power and whether your vehicle can eventually participate in the home energy system.
DOSHI starts with the complete picture before recommending equipment.
START WITH WHAT MOST HOMES USE TODAY
What is Level 2 EV charging?
Level 2 EV charging uses AC electricity, typically at 208 or 240 volts. Your vehicle’s onboard charger converts that AC power to DC before energy reaches the battery.
Level 2 is an excellent solution for many drivers because a vehicle parked overnight often has plenty of time to recharge.
But Level 2 is a category, not one charging speed. The circuit, charging equipment and vehicle all affect the actual power delivered.
THE OPTION MANY HOMEOWNERS DON’T KNOW TO ASK ABOUT
Can home EV charging be faster than Level 2?
Yes. Residential DC charging changes the architecture.
With conventional Level 2 charging, your vehicle’s onboard AC charger is part of the power path.
Residential DC charging can instead deliver DC power to a compatible vehicle through dedicated equipment.
Integrated residential systems can reach charging power such as 25 kW when the vehicle, site and equipment support it.
That does not mean every EV or every home should use DC charging. It means homeowners now have more options to evaluate before building new electrical infrastructure.
Residential DC charging
Potentially higher charging power with compatible vehicles, equipment and electrical design.
Integrated energy
Charging designed with solar, storage, backup, smart loads and bidirectional capability.
THE CHARGER IS ONLY ONE PART OF THE SYSTEM
Your EV. Your home. Your energy.
Designed together.
The next generation of home charging is not simply a faster box on the wall. It is an opportunity to coordinate how energy is generated, stored, used and moved.
BATTERY STORAGE
How much battery storage should a home have?
Battery storage should be sized around what you want the system to accomplish — not around a single product size.
Some homeowners want short-duration backup for essential loads. Others want longer outage protection, time-of-use savings, greater solar self-consumption or enough flexibility to support EV charging as part of the home-energy strategy.
DOSHI favors designs that can grow. When practical, the system architecture, equipment placement, electrical capacity and conduit planning should make future storage expansion easier rather than forcing the homeowner to predict every future need today.
SOLAR INTEGRATION
Should solar and EV charging be designed together?
They should at least be evaluated together. Solar, household loads, battery storage and EV charging all compete for — or contribute to — the same energy system.
The right design depends on when the EV is normally home, how much energy it uses, when solar production occurs, utility rates, available roof or site area, battery goals and whether backup power is part of the plan.
A coordinated design can help avoid creating a solar system, battery system and EV charging system that each work individually but do not work together as intelligently as they could.
BACKUP POWER
What should stay powered when the grid goes down?
Backup design begins with priorities. Refrigeration, lighting, communications, heating or cooling, medical or work equipment, well pumps and other important loads may deserve different treatment than discretionary loads.
Intelligent load management can help a home use available battery capacity more effectively by monitoring and prioritizing loads instead of requiring every circuit to operate at full demand during an outage.
Depending on the home and the owner’s goals, a resilient design may also consider solar production, stationary battery storage, EV charging, vehicle-to-home capability and optional generator integration as parts of the same backup strategy.
THE VEHICLE CAN BECOME MORE THAN A LOAD
What is vehicle-to-home charging?
Vehicle-to-home, or V2H, allows a compatible EV and energy system to send energy from the vehicle battery back to the home.
Bidirectional charging can also enable other applications, including vehicle-to-grid where supported.
Compatibility matters. The vehicle, charging hardware, transfer and safety equipment, software, utility requirements and local electrical rules all have to work together.
THE DOSHI APPROACH
Design for what comes next — not just what solves today’s problem.
Technology will change. A good home-energy design preserves useful choices.
Integrate the vehicle and the home
Treat the EV as part of the home-energy system — not simply another appliance pulling power.
Design for faster charging
Understand what is possible beyond conventional Level 2 before committing to new electrical infrastructure.
Plan for bidirectional energy
Preserve a path toward compatible vehicle-to-home and emerging vehicle-to-grid capability.
Build storage that can grow
Avoid forcing tomorrow’s battery needs into today’s decision. Favor architectures that can expand.
Make solar, storage and charging work together
Design energy flows as one coordinated system instead of assembling disconnected products.
Use intelligent load management
Monitor and prioritize major loads so available electrical capacity and backup energy go further.
Design for resilience
Consider outages, essential loads, backup power and optional generator integration from the beginning.
Preserve future options
Equipment placement, conduit, panel capacity and system architecture should make future upgrades easier — not harder.
BEFORE YOU BUY THE HARDWARE
A 10-year infrastructure decision deserves more than a charger recommendation.
The right answer may be a straightforward Level 2 charger.
It may be faster residential DC charging.
Or it may be a coordinated plan for charging, solar, battery storage, backup power and future bidirectional energy.
DOSHI helps you understand the possibilities, compare architectures and create a plan around the way you actually live — before equipment choices narrow your options.

Level 2, fast home charging, solar, batteries and V2H.
Straight answers to the questions homeowners are asking before they invest in their next charging or energy system.
What is Level 2 EV charging?+
Level 2 charging uses AC electricity, typically at 208 or 240 volts. The vehicle’s onboard charger converts that AC power to DC before the energy reaches the battery. Charging speed depends on the electrical circuit, charging equipment, vehicle and installation.
How fast is Level 2 charging at home?+
There is no single Level 2 charging speed. Actual charging power is limited by the lowest-capacity part of the system, including the electrical circuit, charging equipment and the vehicle’s onboard AC charger.
Can home EV charging be faster than Level 2?+
Yes. Some residential energy systems can support DC charging, which sends DC power to a compatible vehicle without relying on the vehicle’s onboard AC charger. Whether that approach makes sense depends on the vehicle, electrical service, equipment, utility requirements and overall home-energy design.
Can you install DC fast charging at home?+
Residential DC charging is possible with compatible vehicles and equipment, but it is not a universal replacement for Level 2 charging. The right solution depends on available electrical capacity, vehicle compatibility, installation requirements, cost and how charging fits into the rest of the home-energy system.
What is a 25 kW home EV charger?+
A 25 kW residential DC charger can deliver up to 25 kilowatts of DC charging power when the vehicle, equipment and site support that output. Actual charging power may be lower because the vehicle and energy system determine what can be accepted at any moment.
Should I install a Level 2 charger or design a larger home-energy system?+
If you only need reliable overnight charging, a properly designed Level 2 installation may be the best answer. If you are also considering faster charging, solar, battery storage, backup power, intelligent load management or future vehicle-to-home capability, it may be smarter to design those decisions together before installing standalone equipment.
Can solar panels charge an electric vehicle?+
Yes. Solar production can offset the electricity used to charge an EV, and integrated energy systems can coordinate solar, household loads, battery storage and vehicle charging. The ideal architecture depends on when the vehicle is home, solar production, utility rates and the overall system design.
Can a home battery charge an EV?+
Yes, when the system is designed to support it. The more important question is whether using stationary battery capacity for EV charging makes sense for your backup needs, utility rates, available solar generation and other priorities.
Can an EV power a house during an outage?+
Some compatible vehicles and home-energy systems can support vehicle-to-home, or V2H, operation. Compatibility depends on the vehicle, charging hardware, transfer and safety equipment, software, utility requirements and local electrical rules.
How much battery storage does my home need?+
There is no single correct battery size. Storage should be based on what you want to power, how long you want backup to last, your solar production, utility rates, EV charging needs and whether you want the system to be expandable over time.
Should I design solar and EV charging together?+
Usually, yes. Even if the projects are installed at different times, evaluating solar, battery storage, household loads and EV charging together can help preserve electrical capacity, improve energy use and avoid infrastructure decisions that make future upgrades harder.
Can battery storage keep my EV charger running during a power outage?+
It can in a properly designed system, but the answer depends on battery capacity, inverter power, charging equipment, backup architecture, load priorities and the amount of charging power the vehicle requests. In many homes, it may be more useful to prioritize essential household loads and manage EV charging during an outage.
What is bidirectional EV charging?+
Bidirectional charging allows energy to move both into an EV battery and back out again. Depending on the compatible system, that can support vehicle-to-home, vehicle-to-grid and other vehicle-to-everything applications.
