For October’s Road & Track article I covered the ins and outs of EV charging at home, from evaluating your home’s power to purchasing and installing a charger. A section on the advantages of dynamic load balancing is below.
”Of particular value for those who have 100 amp service is the addition of dynamic load balancing. In all homes, you are actually able to have more amperage worth of circuits in your breaker box than your total service can handle. This is acceptable because of ‘load diversity’ or the fact that it is unlikely that you use all of the electrical devices in the home at the same time, so 150 amps of connected load is highly unlikely to reach even 80 amps in practice. Dynamic load balancing takes maximum advantage of this, allowing your EV charger to monitor your whole home’s electricity use and ramp its own use up and down to ensure that your home stays under its allotted maximum load. This means that you can potentially connect a more powerful charger to your home without worrying that you will trip your main breaker.”
