What is the purpose of a site energy management system (EMS) in an EV charging deployment?
Answer: To coordinate building loads, renewable generation, and EV charging to optimize energy use
An EMS coordinates multiple energy systems including building loads, solar generation, storage, and EV charging to optimize overall energy efficiency and cost.
What is a common solution when a site's electrical service capacity is insufficient for the desired number of EVSE units?
Answer: Power sharing and dynamic load management systems
Power sharing and dynamic load management systems allow multiple chargers to share available capacity, enabling deployment without costly service upgrades.
Which utility program incentivizes commercial EV charging by offering reduced electricity rates during off-peak periods?
Answer: Time-of-Use (TOU) rate programs
Time-of-Use rate programs offer lower electricity rates during off-peak hours, incentivizing EV charging during periods of lower grid demand.
What role does a battery energy storage system (BESS) play when co-located with EV chargers?
Answer: It stores energy to supply chargers during peak periods, reducing demand charges
A co-located BESS stores energy during off-peak periods and discharges during peak demand, reducing grid demand and associated demand charges.
What does the electrical service stacking approach provide for large EV charging deployments?
Answer: Multiple utility service entrances to distribute load and avoid a single large service upgrade
Using multiple utility service entrances distributes the total electrical load across separate feeds, avoiding the cost of a single very large service upgrade.
What does grid-friendly EV charging refer to?
Answer: Charging practices that reduce grid stress through load management and off-peak timing
Grid-friendly charging uses smart controls to minimize peak demand, avoid grid stress, and support grid stability through managed and timed charging practices.
