Background
With approximately 80% of EV charging takes place at home, access to at-home charging is a critical component of the shift to electric transportation. Yet while nearly one-third of the U.S. population lives in multi-unit dwellings (MUDs), site managers often face three key challenges when considering adding EV charging infrastructure to their property:
- Limited Power: After power has been allocated throughout the site, the majority of the energy has been accounted for – leaving little room to install charging stations.
- High Infrastructure Costs: To bring in additional power, sites are often confronted with a significant price tag.
- Difficult to Scale: In addition to high upfront costs to upgrade electrical infrastructure, that number will likely only continue to increase as more power and more stations are needed over time.
The EverCharge Solution
EverCharge brings dynamic, scalable, and cost-optimized load management to EV charging via its proprietary SmartPower technology. SmartPower allocates power in real time based on what each vehicle needs.
1. DYNAMIC LOAD MANAGEMENT
SmartPower technology is integrated directly into EverCharge’s charging stations and operates on a wireless mesh network, enabling seamless, instantaneous communication between each station.
Vehicles in multi-family dwellings are not always charging at the same time and almost never need maximum draw during a session to be fully charged. When a vehicle finishes charging or decreases its charging rate, the system instantly re-allocates power to other stations. This is a significant advantage over circuit sharing, which is a simple, static power allocation between a set number of charging stations on one circuit. SmartPower is unique in its ability to pull power across multiple circuits in real time as needed, enabling far more charging sessions than circuit sharing can.
Dynamic load management doesn't stop with efficiently allocating power across the charging infrastructure. SmartPower has the ability to tap into a site’s total available electrical capacity and draw power from unused equipment as needed. For example, SmartPower may temporarily re- allocate unused elevator electricity at night to vehicle charging.
By ensuring the optimal charge is provided to each vehicle – within the limits of the site’s power capacity – electrical capacity requirements are reduced, which dramatically increases the number of stations that can be supported.
2. COST-OPTIMIZED INFRASTRUCTURE
By more efficiently managing power, SmartPower directly lowers the total cost and complexity of EV charging installation and ongoing management. SmartPower’s cost-savings are two-pronged.
Avoid expensive infrastructure upgrades:
- SmartPower works to maximize the site’s existing electrical capacity, rather than needing to bring in additional power and foot the cost for an extensive infrastructure overhaul.
- By operating on a localized wireless mesh network, networking and deployment costs are significantly reduced. Data connectivity is managed per site rather than per device, lowering data fees while eliminating the need to install cellular repeaters. The mesh network also removes
the need for costly control systems, access kiosks, ethernet cables, and other third-party networking systems.
Eliminate unnecessary costs around energy overcapacity fees:
- For traditional charging systems, power consumption may exceed the site’s limit during charging sessions. In doing so, the network operator will charge a far higher utility rate. EverCharge helps prevent this. As soon as the site nears peak consumption, SmartPower will automatically reduce the power allocated to the charging sessions while continuing to sustain a charge. By avoiding these charges, EverCharge saves sites a significant monthly bill.
3. SCALABLE TO MEET FUTURE NEEDS
It is critical to consider not just the site’s current charging needs, but to plan for the future from the beginning. Scaling with SmartPower’s dynamic load management technology is simple and efficient, both from an infrastructure and cost standpoint. With SmartPower, you can avoid adding complexity to your electrical infrastructure as the number of charging stations you can support per site are maximized – both now and for the future. And keeping your infrastructure simple also means scaling without significant, expensive electrical upgrades.
