The IEEE Transportation Electrification Community (TEC) has “graduated” from its status as a program initiative and is now a permanent part of the IEEE. Even though the transition to a permanent organization is complete, TEC is one of the first such communities.

With the rise of Tesla, electrical vehicles (EVs) are becoming a popular alternative to conventional internal-combustion-engine (ICE) vehicles. A recent International Energy Agency (IEA) report projects 20 million passenger EVs will be on the road by 2020 . Of course, EVs do have some limitations – namely cost, driving range, and recharge time. These and other issues have hampered their widespread adoption. Another, often overlooked, issue is that auxiliary systems such as cabin heating and cooling can significantly diminish the driving range if the vehicles’ batteries power them. According to one study , HVAC systems gulp down almost one third of the EV’s total energy reserves at cruising conditions.

If smoking in restaurants and bars has been banned because its effects are bad for human health, shouldn’t large “smoking” vehicles also be banned in densely populated city centers for the same reasons? Certain cities in the European Union are considering just that – by 2050, many cities may allow only zero-emissions vehicles to travel into their city cores1

We discussed in the first article of our two-part series, that electric vehicles had the advantage of a much wider variety of locations that can provide refueling than even conventional vehicles. Home, work, and public locations provide a far greater number of potential fueling (re-charging) points than the 168,000 gas stations (1) in the U.S. While the vast majority of charging is presently performed at home overnight with low or modest rate AC charging, much higher charge rate fast charging like “AC-Fast Charging” (ACFC) or “DC-Fast Charging” (DCFC) may enable more high-utility applications. This report specifically discusses DCFC which has the unique attribute of a direct connection to the DC leads of the vehicle battery for fast-rate charging.

A hybrid energy storage system (HESS) consisting of high-energy-density batteries and high-power-density Ultra-capacitors (UCs) can perform better than a battery alone powering an Electric Vehicle. Hybrid energy storage can harness the benefits of the battery and UCs together and meet the energy storage as well as a vehicle’s power flow requirements. Recent research has focused on a variety of HESS circuit design topologies - and power management and control -. The passive, semi-active, and active HESS configurations have gained significant attention.
About the Newsletter
The Transportation Electrification eNewsletter studies topics that span across four main domains: Terrestrial (land-based), Nautical (Ocean, lakes, and bodies of water), Aeronautical (Air and Space), and Commercial-Manufacturing.
Our topics include the following:
- E-Bus/E-Truck (Heavy Duty Mass Transit)
- E-Utility Vehicles (Golf Carts/Garbage Trucks/Forklifts/Agriculture, etc.)
- Aircraft/Aerospace/UAVs or Drones
- Seaport and logistics
- Micro (personal) E-mobility (eBikes/scooters/tuktuk)
- Autonomous E-mobility
- Charging/Plugged/Wireless (including power utility & electronics)
- Policies, Standards, Regulations & others
The TEC eNewsletter is now being indexed by Google Scholar.
Coming Soon, the 2020 Call for Articles and Submission Guidelines.
