Busway

EV charging busway

EV charging busway is engineered to enable fast, flexible and scalable electric vehicle (EV) charging for fleet, services with multiple passenger or medium-duty vehicles and last mile delivery. This innovative overhead solution utilises Pow-R-Way III busway and incorporates a 19.2 kW AC Level 2 charger into the bus plug for direct vehicle charging. Using the busway for EV charging provides a future-proof and scalable footprint with the convenience of a busway’s plug and play features.

How EV charging busway compares to fleet charging alternatives 

eaton-busway-infographic-full-landscape-en-us.png

Alternative EV fleet charging

Complex, bulky and overcomplicated

More components
Extra pieces of equipment mean added weight and cost.
More equipment adds extra steps and factors multiple interfaces into installation.
More equipment adds extra steps and factors multiple interfaces into installation.
Greater vulnerability
Ground-level EV charging pedestals or wall units are more susceptible to damage and additional wire connection points means greater potential for issues.

Innovative EV charging busway

Streamlined, cost-effective and highly scalable

Modularity
Ideal for a phased approach for converting a facility to EV charging and provides flexibility for spacing of charging drop locations.
Cost-effective installation
Overhead EV charging stations avoid the need for costly trenching or boring as well as major modifications to existing structures.
Enhanced serviceability and reliability
Maintains proper tension on cables and power transfer from station to vehicle. Connected Cable Management System (CCMS) allows for easy access when needed to help reduce downtime.

EV charging busway FAQ

 

What is a busway and how is it powered?

The busway is an efficient power distribution solution that includes three core elements – conductors, housing and insulation. The busway is powered upstream by properly sized overcurrent protection device. The busway can operate up to 600 V and can carry continuous current of 5,000 A.

Can the EV charging busway be used in outdoor installations?

At this time, the EV Charging Busway solution is only available for conditioned indoor installations.

What is an EV bus plug and how is it powered?

Bus plugs are the primary connection points for tapping into the power supplied by the busway. An EV bus plug includes an AC Level 2 EV charger along with a properly sized overcurrent protection device. Bus plugs are easy to install and flexible to relocate along the busway.

What voltage should be supplied to an EV charging busway?

Eaton 19.2 kW AC Level 2 chargers operate from 208 to 240 Vac when applied on 240/120 Vac single-phase 3-wire or 208/120 three-phase 4-wire electrical distribution systems. Contact Eaton for other special voltages and electrical distribution systems.

How many EV bus plugs can I install on an EV charging busway?

This depends on multiple factors including current rating of the busway, voltage rating of the system and the EV charger rating. For example, a 4,000 A busway powered by a 240 V 3-phase Wye system can support up to sixty (60) EV bus plugs rated at 19.2 kW each. This also takes phase balancing into consideration. Each installation can be different and Eaton’s experts are available to support your EV charging needs.

Do EV bus plugs come with cable management?

EV bus plugs come with an accessory retraction unit that provides an effective cable management solution. This retraction unit is spring-loaded with a ratcheted lock. Adjustable tension, secondary support and automatic locking provide additional safety.
