Frequently Asked Questions

What type of vehicles does FPG Electrified (FPG-E) currently offer?

FPG Electrified is presently setting up dealer arrangements with several Battery Electric Vehicle (BEV) manufacturers for light and medium-duty Command and Rescue trucks ranging from Class 4 through Class 6, or GVWRs from 14,000 through 26,000 pounds. Detailed information on FPG-Eโ€™s vehicle product suite will soon be available on this website.

What is the vehicle range and how long does it take to charge?

Range varies according to the size of the truck, its duty cycle and its battery capacity. A standard, electrified F-650 chassis will hold 150 kWh of energy. With the average energy consumption for a Class 5 or Class 6 electric vehicle at 1.5 kWh per mile the range would be 100 miles.


Using a Level 2 charger at 240V with 80A electrical supply equipment and a vehicle charge rate (standard) of 19.2 kW, charge times are as follows. (Note: Battery state of charge (SOC) should not fall below 20%.)

Level 3 charging equipment (also called DC Fast Chargers) charge through a 480V, direct current (DC) plug. The F-650 chassis indicated above will charge at a rate of 50 kW. A 100 mile range vehicle can be fully charged in less than an hour. Level 3 chargers are about 10x the cost of a Level 2 charger.

What kind of accessories can I get with my Command or Rescue vehicle and how much energy will they consume?

Each Electric Vehicle will be accessorized to the customerโ€™s specific requirements. Available accessories could include:

  • Solar charging panels / systems (200 to 400 watt)
  • Electric water heaters
  • WIFI boosters
  • Auxiliary battery capacity systems (Lithium batteries for extended EV operation of accessories, lights, radios, cell phone chargers, AC outlets, etc).  
  • Auxiliary electric heaters and air conditioners
  • Electric refrigerators or freezers
  • Cooking systems (all electric induction or microwave, etc).
  • Shore power connections for charging auxiliary batteries or running electric accessories

Depending on accessories and usage, battery power consumption could range from 20 kWh to 40 kWh per day. So, a 150 kWh battery pack, fully charged, could operate off the grid from 4 to 8 days (not including transport to/from the depot.)

How long do EV batteries last?

As batteries wear, their capacity to absorb a charge diminishes. So the range of electric vehicles will diminish with age. Most OEMs have an 8-year or 100 miles warranty period (with a maximum of 20% degradation) on their batteries. In California and 15 other states that follow California emissions laws, OEMs will have to warranty the batteries to 10 years or 150,000 miles which will most likely become the national standard within the next 2 years.

In addition to an electrified Mobile Command or Rescue vehicle, I would like to electrify other gas or diesel vehicles within my fleet. How do I determine the optimum fleet configuration?

FPG Electrified will work with each customer to help determine which type and quantity of EV models best fit their fleetโ€™s needs. FPG Electrified's Fleet Electrification Assessment will evaluate a number of different factors including an inventory of existing vehicles, maintenance and fuel costs, life cycle and duty cycle, routes, etc. The output of the Assessment will include recommendations for EV replacement types, number of vehicles, initial capital investment, total cost of ownership (operating costs) and estimated reduction in emissions.

What is Vehicle-to-Grid?

V2G stands for โ€œvehicle-to-gridโ€ and is a technology that enables energy to be pushed back to the power grid from the battery of an electric vehicle. In a nutshell, the idea behind vehicle-to-grid is similar to regular smart charging. Smart charging, also known as V1G charging, enables the user to control the charging of electric cars in a way that allows the charging power to be increased and decreased when needed. Vehicle-to-grid goes one step further and enables the charged power to also be momentarily pushed back to the grid from vehicle batteries to balance variations in energy production and consumption. Since at any given time 65 percent of electric vehicles are parked, the batteries in electric vehicles act like mobile power plants and let electricity flow from the vehicle back to the electric distribution network. Research on potential earnings associated with V2G found that with proper regulatory support, medium duty electric vehicle owners employing V2G technology could earn (save) several thousand dollars a year.
