What technology allows for reduced energy costs during off-peak hours?

The technology that allows for reduced energy costs during off-peak hours is flexible charging systems. These systems enable the scheduling and management of when electric vehicles (EVs) or devices are charged, allowing users to take advantage of lower electricity rates that are often offered during off-peak periods. By shifting charging times to these less expensive periods, operational costs can be significantly reduced, contributing to both energy efficiency and cost savings.

The other options do not provide the same benefits related to energy cost management. Advanced navigation systems focus on directing vehicles efficiently but do not involve energy costs directly. Smart surveillance technologies are utilized for security monitoring and do not influence energy pricing. Similarly, automatic speed controls pertain to vehicle operation efficiency rather than energy cost optimization during different time frames.
