Summary
The Urban EV Podcast features Andrew Richard, chief revenue officer at Electrify EVSE, and Wayne Price, vice president of engineering at Electrify Hub. The discussion focuses on the infrastructure challenges slowing fleet electrification and how mobile DC fast-charging systems can help businesses transition to electric vehicles without waiting years for permanent charging infrastructure.
1. The EV charging infrastructure problem
The guests identify inadequate charging infrastructure as one of the biggest obstacles to fleet electrification. Businesses may be ready to replace internal-combustion vehicles with EVs, but they often cannot get the electrical capacity needed to charge them.
The main challenges include:
- Long equipment lead times: Electrical switchgear and other charging infrastructure can take months or even years to obtain.
- Expensive grid upgrades: Some facilities require new substations and high-voltage transmission lines, potentially costing millions of dollars.
- Permitting delays: Municipal inspections, site requirements and other administrative hurdles can significantly delay installations.
- Limited charging availability: Electric buses, delivery vehicles and other fleet vehicles can sit idle because their depots lack sufficient charging capacity.
California faces particularly strong pressure to electrify fleets because of its emissions regulations, but the guests emphasize that these challenges affect businesses nationwide.
2. Electrify Hub: A mobile charging grid
Electrify Hub addresses the infrastructure gap by providing mobile charging units that function as self-contained power sources. Rather than waiting for a utility to upgrade a facility, a fleet operator can bring one of these units onto its property and begin charging vehicles.
Key features include:
- DC fast charging: The systems provide higher charging power than conventional Level 2 chargers.
- Alternative fuels: Units use renewable propane or compressed natural gas rather than gasoline or diesel, according to the guests.
- Turnkey service: The companies handle permitting, fuel delivery, equipment deployment and ongoing support.
- Backup power: The units can be switched from vehicle charging to supplying electricity to a building or other facility.
- Mobile deployment: Systems can be relocated as fleet requirements change or permanent infrastructure becomes available.
The guests describe the technology as a bridge between today's charging needs and the eventual installation of permanent electrical infrastructure. They do not claim it will replace grid-connected charging in every application.
3. Electrify EVSE's role in charging deployment
Andrew Richard explains that Electrify EVSE has provided turnkey charging installations and infrastructure services across the United States, Canada and Costa Rica.
The company began encountering increasingly severe infrastructure delays around 2018 and 2019. Projects that once required weeks or months began facing lead times measured in years.
Richard cites large projects involving dozens of Level 2 chargers and DC fast chargers that experienced substantial delays because of equipment shortages, permitting and the difficulty of bringing sufficient electrical power to a site.
Electrify EVSE works with customers to develop phased electrification plans. These plans evaluate what a business needs immediately, what its fleet might require over the next three to five years, and what permanent infrastructure will eventually be necessary.
This approach allows customers to make progress toward sustainability goals while avoiding premature investments in infrastructure that might not match their future needs.
4. Environmental benefits and trade-offs
The podcast acknowledges that generating electricity from an alternative fuel is not the same as charging vehicles directly from a renewable-powered grid.
Price argues that the environmental comparison depends on the local electricity mix. Some grids still rely heavily on fossil fuels, while others have greater access to renewable energy.
He says Electrify Hub's renewable propane and compressed natural gas systems can provide a lower-carbon alternative to some conventional power sources. The units also offer backup power in places where grid reliability is a concern.
However, the transcript does not provide emissions figures, lifecycle analyses or independent comparative data to quantify the environmental advantage. The guests' claims should therefore be understood as their assessment of the technology rather than a demonstrated emissions comparison applicable to every location.
5. Temporary solutions can become permanent
One of the most interesting themes is that mobile charging often remains in service longer than customers originally anticipate.
Price describes customers initially treating mobile units as temporary equipment while waiting for permanent grid connections. As utility projects are repeatedly delayed and costs increase, the mobile systems become an established part of their operations.
Customers discover that they can charge their vehicles reliably, meet sustainability targets and retain backup power for their facilities.
Richard also describes writing multiple contract extensions for an autonomous vehicle operator because the company's promised permanent infrastructure kept getting delayed.
The guests argue that mobile charging's value extends beyond filling a short-term gap: it can provide operational resilience and predictable access to energy while long-term projects remain uncertain.
6. Fleet applications and real-world examples
Electric buses and commercial fleets
Bus operators and other fleet owners can use mobile charging when their depots lack sufficient electrical capacity. This is particularly useful for larger operations that need to charge multiple vehicles on tight schedules.
Delivery and last-mile logistics
Delivery fleets increasingly operate for 12 to 14 hours a day, according to the discussion. That intensity can make overnight Level 2 charging insufficient and increase the need for DC fast charging.
Autonomous vehicles and robotaxis
Autonomous fleets can require rapid, repeated charging between shifts. Price describes a previous operation that charged approximately 300 vehicles each night, illustrating the scale of energy demand these fleets can generate.
Events and emergency response
Mobile units can provide charging and power for event facilities, medical tents and temporary work sites. Following natural disasters, they can help charge EVs and subsequently supply electricity to response teams and temporary camps.
Automotive testing
Automakers can deploy mobile fast chargers at remote proving grounds and testing locations. Richard says this can substantially shorten testing schedules by eliminating trips to distant public charging stations.
The guests also describe participating in NBC Sports' Charge Across America event in 2020. Their mobile units provided emergency charging to EVs that could not reach conventional charging stations, helping demonstrate that cross-country EV travel was possible even when public charging coverage was limited.
7. Charging speed, reliability and engineering
Electrify Hub's mobile systems can deliver up to approximately 180 kW in the configuration discussed. Price says units at this power level can fit into a standard parking space, while larger configurations may require substantially more room.
Operating reliably in extreme temperatures has required considerable engineering. Price describes systems designed to manage internal temperatures through active heating, cooling and airflow control.
The company also emphasizes software diagnostics, telemetry and responsive technical support. Richard says technicians can be dispatched quickly when problems arise, an important consideration when charging supports critical fleet operations.
Their argument is that these systems are much more sophisticated than simply placing a generator and charger on a truck. Thermal management, controls, diagnostics and service infrastructure are essential to making mobile fast charging dependable.
8. Why public charging and permanent installations remain difficult
The discussion turns to the economics of conventional charging infrastructure, particularly Level 2 chargers at destinations such as shopping malls, golf courses, hotels and residential properties.
Businesses must weigh installation costs, software fees, utility upgrades, projected EV usage and potential charging revenue. A property owner may invest substantial sums only to discover that charging income does not justify the expenditure.
The guests also discuss uncertainty surrounding government funding, including the federal NEVI program. They argue that funding uncertainty can slow investment, although private companies with sustainability commitments may continue to deploy chargers.
Their broader point is that charging infrastructure is not simply a matter of installing equipment. It requires a viable business case, adequate electrical capacity, permitting, software and a clear understanding of future demand.
9. The next five to 10 years
The guests expect mobile charging demand to grow, particularly in applications requiring high utilization and rapid charging.
Price highlights two important developments:
- Autonomous vehicle fleets: Companies operating robotaxis may need to charge large numbers of vehicles quickly and repeatedly. Some fleet models return vehicles to centralized depots, creating concentrated charging demand.
- Electrified delivery fleets: Companies such as Amazon are deploying electric delivery vans, but expanding delivery hours and seasonal peaks can create charging requirements that exceed available capacity.
The discussion distinguishes between distributed charging models, in which vehicles may charge at many locations, and centralized fleets that return to depots. The latter are especially attractive applications for mobile DC fast-charging systems.
The guests remain cautious about predicting the ultimate form of the EV charging network. Battery technology, grid expansion and fleet operating models will continue to evolve, but they believe mobile charging can address immediate needs during that transition.
Key takeaways
1. Charging infrastructure is a major bottleneck for fleet electrification. Utility upgrades, equipment shortages, permitting and costs can delay projects for years.
2. Mobile DC fast charging provides a practical workaround. Self-contained charging units can supply power before permanent grid connections are ready.
3. Fleet operations are a particularly strong use case. Electric buses, delivery vans, autonomous vehicles and automotive test fleets need dependable charging that fits their operating schedules.
4. Mobile systems offer value beyond charging. Their ability to provide backup electricity makes them useful for emergencies, events and facilities with unreliable power.
5. The environmental case depends on the energy source. Alternative-fuel generation may reduce emissions compared with some conventional sources, but the transcript provides no independent data to quantify the advantage.
6. Charging economics remain challenging. Businesses must consider utilization, infrastructure costs, utility capacity and return on investment before committing to permanent installations.
7. Fast charging is becoming increasingly important. As commercial fleets operate longer hours and autonomous vehicles scale up, conventional overnight charging alone may not be sufficient.
Overall conclusion: The podcast presents mobile EV charging as a practical infrastructure bridge rather than a universal replacement for permanent charging stations. Electrify EVSE and Electrify Hub aim to help fleets electrify sooner, maintain operational reliability and manage the uncertainty surrounding grid upgrades. Their strongest potential lies in high-demand commercial applications where waiting for permanent electrical infrastructure would leave expensive electric vehicles sitting idle.
