4 FAQs about Large energy storage vehicle numbering rules

Are battery electric vehicles a rechargeable energy storage system?

Except as specified in paragraph (h) of this section, battery electric vehicles and plug-in hybrid electric vehicles must meet requirements related to batteries serving as a Rechargeable Energy Storage System from GTR No. 22 (incorporated by reference, see § 86.1).

How many kWh can you put in a garage?

In all other locations noted above, the size limit is 80 kWh. On the exterior walls of the home, it's important to note that systems cannot go within 3 feet of doors or windows leading directly into the home. And as we will soon discuss, code compliance for ESS in an attached garage can be much more complicated than systems in a detached garage.

What if a vehicle does not comply with battery durability requirements?

If vehicles do not comply with these battery durability requirements, the manufacturer must adjust all credit balances to account for the nonconformity by forfeiting GHG credits calculated for all the vehicles within the test group (see § 86.1865-12 (j) (3)).

What is an energy storage system (ESS)?
