Adaptive Power FAQs: Smart Charging Solutions (EVEMS) for Buildings with Limited Electrical Capacity

Updated: Jun 26

As more people switch to electric vehicles (EVs), having efficient and accessible charging infrastructure is increasingly crucial. However, high-density buildings possess distinct requirements from single-family home charging solutions. VariableGrid's EV Energy Management System (EVEMS) technology offers a tailored solution for buildings with high-density parking amenities with limited electrical capacity.

Designed specifically for condos, townhome complexes, and other multi-unit residential buildings, our system ensures fair access to EV charging while optimizing available energy for widespread electrification. By preparing all parking spaces to be "EV Ready," VariableGrid's technology enables convenient at-home charging for residents both now and in the future.


Additionally, our innovative approach to infrastructure optimization reduces the need for expensive upgrades during installation, making the process more cost-effective while maximizing efficiency.


With features like branch circuit sharing, our system intelligently distributes power among multiple EV chargers, preventing overloads and enhancing safety.


Explore the FAQs below to learn how VariableGrid's technology can address the increasing demand for EV charging solutions without compromising convenience or necessitating costly infrastructure upgrades.


EVEMS: Frequently Asked Questions 


VariableGrid's adaptive power solutions for high density buildings: 


How do VariableGrid's solutions work for buildings with limited electric capacity?

Our EV energy management systems, tailored for multi-unit residential buildings (VarianPRO) and townhomes (VarianSENSE), intelligently coordinate power distribution among multiple EV chargers within your building. This guarantees fair access to charging while maximizing your available energy for complete electrification. Through dynamic power allocation and features such as branch circuit sharing, our system optimizes current infrastructure, reducing expenses while ensuring dependable and convenient EV charging for all residents.


Can VariableGrid's system adapt to future technological advancements in EV charging?

Absolutely. VariableGrid's EVEMS is engineered to expand alongside the increasing demand for EV charging. Whether it involves installing more charging stations or accommodating larger fleets of electric vehicles, our system can adjust to fulfill your evolving requirements without necessitating extensive upgrades or disturbances to your building's infrastructure.


How does VariableGrid optimize existing infrastructure?

VariableGrid's controller efficiently manages and allocates the current electricity supply, eliminating the need for costly infrastructure upgrades.


What is branch circuit sharing and how does it cut down on installation costs?

Branch circuit sharing enables multiple EV chargers to utilize a single electrical circuit. VariableGrid regulates power distribution to these chargers, preventing circuit overload. This approach substantially reduces installation expenses by minimizing the necessity for additional circuits.


Can VariableGrid future-proof a building's energy infrastructure?

VariableGrid adeptly manages power distribution to EV chargers, accommodating the rising demand for EV charging without expensive infrastructure upgrades. Additionally, it supports standard communication protocols like OCPP, ensuring compatibility with forthcoming EV charging technologies.


Managing Building Demand and Charging Habits:


How quickly can VariableGrid respond to changes in building demand?

VariableGrid can promptly adapt to fluctuations in building demand, adjusting power allocation to EV chargers in real-time as demands from other building uses shift.


How does VariableGrid handle peak demand times in the building?

The VariableGrid EVEMS Controller continuously monitors the building's energy consumption. During peak demand periods, such as when residents return home and begin using appliances, the system intelligently reduces the power allocated to EV charging. This prevents the building's total energy demand from exceeding its capacity.


What occurs with EV charging during high building demand?

During times of elevated overall building energy demand, the VariableGrid Controller can temporarily decrease or pause EV charging. This action allows the building's electrical system to manage the increased load from appliances and other uses without risking overload.


Will EV users need to adjust their charging habits to accommodate numerous chargers?

There's no need for EV users to alter their charging habits with VariableGrid’s technology. In fact, the EVEMS efficiently manages charging, ensuring vehicles receive the most available power while optimizing overall building energy usage.



Metering, Billing, and Security:


Can VariableGrid handle EV charger metering and billing?

VariableGrid can track the energy consumption of each EV charger, facilitating metering purposes. This data can also be utilized for billing if residents are charged for the electricity used to charge their vehicles.


How does VariableGrid guarantee the reliability and security of the charging stations?

VariableGrid employs robust security measures, including encrypted communications, secure access controls, and regular security audits, to prevent unauthorized access and ensure the safety and integrity of the charging process.


Is VariableGrid's EVEMS easy to navigate?

VariableGrid's EVEMS is designed with user-friendliness in mind, offering various control and configuration options, detailed reports, and real-time status updates for ease of use.
