Greenlots to collaborate with Volvo Vehicles on electrical truck charging infrastructure for fleets in Southern California; SAE J3068

Greenlots, a world supplier of EV charging software program and options, will collaborate with Volvo Vehicles to deploy charging infrastructure for electrical vans working out of warehouses in Southern California. That is the primary heavy-duty fleet-charging mission stemming from a big public-private partnership with the California Air Assets Board (CARB).

CARB awarded $44.eight million to the South Coast Air High quality Administration District (SCAQMD) for Volvo’s Low Affect Inexperienced Heavy Transport Options (LIGHTS) mission. As a part of this mission, Greenlots will outfit warehouses with heavy- and light-duty charging infrastructure, combine the chargers with onsite photo voltaic PV and vitality storage methods and leverage Greenlots’ charging community administration software program to deploy Volvo’s first electrified vans in North America.

The entire charging gear for the mission—together with each Stage 2 chargers and 150kW DC fast-chargers—will function on Greenlots’ SKY enterprise software program platform to allow seamless administration of Volvo’s fleet, charging stations and vitality storage methods.

Volvo Vehicles’ connectivity system may even be built-in to offer truck operators with a complete view of their autos’ operational and charging readiness.

Greenlots will work with ABB and different charging station producers to offer the gear, whereas partnering with Burns & McDonnell to engineer, assemble and set up the brand new EV charging stations. The mission can be one of many first in North America to display a brand new heavy-duty car charging normal, SAE J3068 (earlier put up), in real-world functions.

SAE J3068 is a really helpful observe for conductive charging of EVs and provide gear that use three-phase AC energy. SAE J3068 standardizes an AC three-phase-capable coupler and digital management protocols.

This new normal was designed to supply a single car charging coupler resolution for three-phase and single-phase AC and DC charging for a category of autos. We needed to mix this new strategy for AC charging with 1000V DC charging primarily based on current SAE communication requirements.

Particularly, SAE J3068 supplies for the next:

  • A better energy model of an current cost coupler; e.g., 133 kW at 480 VAC 160 A 3-phase.

  • Bi-directional digital communication between the EV and the EVSE through single wire baseband signaling for native management.

  • Grid provide voltage is signaled earlier than the EV and SE comply with cost. For instance, in Canadaa 600 VAC is extra frequent that 480 VAC however not all EVs can make the most of 600 VAC.

  • Impartial management of present limits on a phase-by-phase foundation.

  • The EV might sign requested present to allow an influence administration system to steadiness masses higher.

Solely symmetric three-phase AC suppleis are supported within the first version; uneven provides reminiscent of corner-grounded Delta and Excessive-Leg-Delta possibly supported sooner or later.
