1.0 SCOPE

This specification establishes the minimum requirements for zero-emission transit buses (ZEBs) of both battery electric buses (BEBs) and fuel cell electric buses (FCEBs). This specification is not intended to dictate any specific design, but rather indicate the base type of bus and equipment desired by the State. This specification defines requirements for a heavy-duty and cutaway ZEBs to be used for both suburban express service and general service on urban arterial streets. Specific options not included in this specification for the base ZEB shall be configured directly with the manufacturer and/or dealer.

Intent is to maximize passenger appeal in appearance, comfort, and safety combined with excellence in reliability, operating characteristics, and economy of operation. The ZEBs are for seating a wide spectrum of ambulatory and wheelchair passengers including children, adults, elderly, and people with disabilities.

The contractor shall ensure that the application and installation of major subcomponents and systems are compliant with all such subcomponent vendors’ requirements and recommendations.

Components used in the vehicle shall be of quality design and capable of transit service.

The ZEBs may be referenced as “the bus” for this specification and requirements.

3) Bus: The California definition is found in Vehicle Code Section 233: (b) A vehicle designed, used, or maintained for carrying more than 10 persons, including the driver, which is used to transport persons for compensation or profit, or is used by a nonprofit organization or group, is also a bus.

4) Charging Equipment: The equipment that encompasses all the components needed to convert, control and transfer electricity from the grid to the vehicle for the purpose of charging batteries. May include chargers, controllers, couplers, transformers, ventilation, etc. See Electric Vehicle Supply Equipment (EVSE).

5) Cutaway Bus: A cutaway bus is a type of vehicle that is manufactured in two stages. The first stage is to build a truck or van cab and chassis, known in the industry as a commercial cutaway. The second stage is the installation of the bus body and passenger seating compartment onto the cutaway.

6) Design Operating Profile: The operational requirements under standard operating conditions that the bus must be able to achieve.

7) Electric Vehicle Supply Equipment (EVSE): The conductors, including the ungrounded, grounded and equipment grounding conductors, the electric vehicle connectors, the attachment plugs, and all other fittings, devices, power outlets or apparatuses installed specifically for the purpose of delivering energy from the premise’s wiring to the electric vehicle.

8) Energy Storage System (ESS): A component or system of components that stores energy and for which its supply of energy is rechargeable by the on-vehicle system (engine/regenerative braking/generator) or an off-vehicle energy source.

9) Gross Vehicle Weight Rating (GVWR): The maximum total weight as determined by the vehicle manufacturer, at which the vehicle can be safely and reliably operated for its intended purpose.

10) Low-Floor Bus: A bus that, between at least the front (entrance) and rear (exit) doors, has a floor sufficiently low and level so as to remove the need for steps in the aisle between the doors and in the vicinity of these doors.

11) Regenerative Braking: Deceleration of the bus by switching motors to act as generators, which return vehicle kinetic energy to the energy storage system.

12) ZEB: A bus that emits no tailpipe emissions from the onboard source of power.
