A grid-integrated EV is defined as a battery-powered motor vehicle that has the ability for two-way power flow between the vehicle and the electric grid as well as communications hardware and software that allow for external control of battery charging and discharging. (Reference Delaware Code Title 26, Chapter 10, Section 1001 and 1014g)
Idle Reduction Weight Exemption
Any motor vehicle equipped with qualified idle reduction technology may exceed the state gross, axle, tandem, or bridge weight limits by up to 400 pounds to account for the weight of the technology. The additional weight may not exceed the actual weight of the idle reduction unit. To qualify for the exemption, the vehicle operator must also be able to prove the weight of the idle reduction technology and demonstrate that the technology is fully functional. (Reference Delaware Code Title 21, Chapter 45, Section 4503f)
