Prisoner Transport Goes Electric:
HEAVY-DUTY EV INMATE TRANSPORT IS HERE
Phillip Oldridge
The Cobb County Sheriff’s Department in Marietta, Ga., made history in October 2022 when the agency took delivery of the first modern, all-electric inmate transport van in the U.S. The move signals an innovative and exciting new era for Cobb County and a glimpse at the cleaner, more efficient, and more cost-effective future of law enforcement fleets. From an environmental and financial perspective, it’s an example that other law enforcement agencies would be wise to follow.
The high-roof, all-electric transport van is a rugged, heavy-duty workhorse that will provide years of emissions-free service for Cobb County. To stay cost-effective, the transport utilizes commonly available bolt-in upfit components to transform the cargo bay into a secure, safe, fully-mobile containment area for several inmates. With a top speed of 63 mph, 575 ft-lbs. of instant torque and an estimated range of 170 miles on a full charge, Cobb County’s EV inmate transport is a no-compromise solution that just makes sense.
The new van replaces an older, diesel-powered model and will allow Cobb County to securely move prisoners with zero emissions, healthier interior air quality for both personnel and inmates, and much less noise. Between more stable fuel costs and reduced maintenance due to the lack of belts, hoses and crankcase oil that need to be regularly inspected and changed, officials expect the transition to EV transport will save Cobb County around $40,000 in the first three years of operation.
It’s a smart move for taxpayers, for Cobb County and for other agencies who’d be interested in following their lead. With heavy-duty commercial electric vehicles becoming more affordable and available, municipalities and city governments are fast running out of excuses for not transitioning their fleets, including inmate transport.
Sweetening the pot even further is the fact that recent federal legislation like the Inflation Reduction Act contains tens of billions in grants for municipalities, non-profits, tribal nations, and county governments that are specifically designed to help make EV fleet transitions and charging infrastructure much cheaper or even free. Most states and even some local electric utilities also offer grant funding for EV exploration, transition, infrastructure, and procurement.
To help municipal governments access that growing pot of federal EV transition dollars more easily, EV manufacturers have stepped up to provide free grant-writing and EV master planning services for governments, nonprofits, and school districts.
Even beyond the affordability of a transition, several other factors make inmate transport vehicles desirable targets for a switch to EV.
The Demands of Inmate Transport are a Perfect Fit for EV
Most secure inmate transport in the U.S. involves short, predictable routes, such as moving prisoners from county jails to the local courthouse or transfers from smaller jails to a centralized detention center.
As a result, the daily mileage traveled by most inmate transports is usually low and well under the 170-mile estimated range of the Cobb County van. With today’s long-range commercial EVs, inmate transports just do not need a fuel-hungry, high-maintenance diesel engine under the hood to do the job effectively anymore.
Inmate Transportation Generally Allows Plenty of Time for Recharging
Another mark in favor of transitioning inmate transport to EV is the extended “downtime‚ most transports experience during the day.
Many transports spend extended periods parked overnight or during the day sitting idle outside the jail or courthouse, usually in a specific, designated space. That extended downtime is the perfect opportunity for charging. Level 1 chargers can be installed for the most cost-effective charging where the vehicle spends its “dwell time‚ overnight.
Electricity rates for most areas are at rock bottom prices per kilowatt hour at night, helping keep batteries topped off for less. Speedier Level 2 or 3 chargers can be placed next to the transport’s designated space outside the courthouse or detention center. Park, plug the vehicle in through a simple connector, and downtime becomes range-extending charging time.
EV Inmate Transports Can Be Utilized as Electrical Backup
Yet another positive for transitioning to EV inmate transport is the potential for agencies to use the vehicle’s battery as a source of emergency electricity.
Packed with heavy steel containment hardware, inmate transport vans aren’t going to win any races at the local track. In EV transport, getting that weight up to highway speeds while extending available range requires large, high-capacity battery packs. For law enforcement agencies, that big, mobile battery presents an opportunity in times of crisis.
Detention Centers, Sheriff’s offices, police stations, and emergency shelters need reliable electricity. Suppose the power goes out in your community due to a violent storm, record flood or grid overload. In that case, an EV inmate transport can ride to the rescue and keep emergency power flowing with a simple connection.
Even without that kind of crisis, there are myriad ways law enforcement agencies can utilize that “battery backup‚ capacity of EV transports. Criminals don’t work 9 to 5, so agencies of all sizes often need to provide electrical power or high-intensity lighting during nighttime investigations, sometimes far from any available power source. With an EV inmate transport van or EV mobile command center in your fleet, bringing hours of reliable electrical power to any scene is as simple as pulling up and plugging in.
EV Inmate Transport Improves Local Air Quality
Another nod for transitioning to EV inmate transport is the potential to help lower air pollution in our towns and cities. Due to the downtown or inner-city location of many jails, courthouses and law enforcement facilities, thousands of inmate transport vans nationwide see daily use in stop-and-go traffic.
In addition to dramatically spiking fuel use, stop-and-go city driving can greatly increase the carbon emissions produced by gasoline and diesel engines. In cold climates, diesel-powered transports may also be left idling for extended periods to reduce start-up issues, further increasing harmful emissions.
According to the EPA, diesel emissions have serious impacts on air quality and health, upping the incidence of asthma and
respiratory illness, particularly in children and the elderly, while making existing heart and lung conditions worse. Diesel exhaust and particulates are also known carcinogens. But by switching to EV inmate transport, law enforcement can help become part of the solution instead of another contributor to a problem harming citizens and our environment.
By transitioning to EV inmate transport, agencies can help improve air quality in cities and towns and reduce or eliminate toxic diesel exhaust fumes in secure loading areas and inside vehicles. The result is healthier air for communities, detention staff and inmates needing secure and safe transportation.
By following the example set by the Cobb County Sheriff’s Office and transitioning inmate transport to EV, law enforcement agencies nationwide can save taxpayer dollars and spend thousands less per year on fuel and maintenance costs. In the process, they can help create a cleaner, brighter future for us all and healthier conditions for inmates and law enforcement personnel. Those are achievable goals any public servant should be able to get behind.
