THE FOUR LEVELS OF EV CHARGING ENERGY MANAGEMENT: A GUIDE TO SMARTER EV CHARGING 12 <br />Performance Management <br />and Optimization <br />Peak shaving in action: During a hot summer <br />afternoon, the system predicts air conditioning will <br />push building demand near the utility threshold. It <br />automatically reduces EV charging from 40 amps to 15 <br />amps across all chargers, preventing a demand charge <br />spike while maintaining some charging capability. <br />Off-peak optimization: Late evening and early morning <br />hours often provide maximum charging speeds (35-40 <br />amps) when building loads are minimal and utility rates <br />may be lower. <br />Seasonal adaptation: The system learns that winter <br />months have different peak patterns than summer, <br />adjusting charging strategies accordingly. <br />The Trade-offs <br />This represents the most complex installation, requiring <br />careful coordination between multiple stakeholders— <br />building management, electrical contractors, utility <br />companies, and your EV charging solutions provider. <br />However, properties with substantial demand charges <br />typically see attractive ROI through operational savings, <br />making this level worth serious consideration for the <br />right applications. <br />Best applications <br />Commercial properties with substantial monthly <br />demand charges on utility bills. Buildings implementing <br />comprehensive energy management strategies. <br />Premium properties pursuing best-in-class building <br />systems. Installations where controlling operational <br />expenses is a primary objective.
