How To Fast-Charge An EV On A 100-Amp Panel (No Upgrade Required) - CleanTechnica

The article from CleanTechnica explains how homeowners with a 100-amp electrical panel can install a high-speed Level 2 electric vehicle (EV) charger without costly panel upgrades, which typically range from $2,000 to $5,000. Although Level 2 chargers draw significant current (16A to 48A), most homes do not use their full panel capacity simultaneously. By employing smart load management technologies and adhering to recent National Electrical Code (NEC) updates, it is possible to safely install and operate a Level 2 charger on a 100A panel. Certified energy management systems (EMS) can cap total current draw, preventing overloads by temporarily reducing or pausing EV charging when other high-demand appliances are in use. Several load-sharing solutions enable this approach: dedicated EMS devices like the Thermolec DCC-12 monitor total home load and manage EV charging accordingly; smart splitters such as the NeoCharge Smart Splitter alternate power between an EV charger and another appliance on
