Glossary

Glossary of the course.

E-Mobility and E-Buses can be complex and are part of a broad field. Therefore, the most important terms related to this two terms are introduced here. Please keep this glossary in mind as you progress through the course and come back whenever you do not understand a word.

  • Battery Pack:
    • It is a set of any number of (preferably) identical batteries or individual battery cells.
  • Battery Electric Bus (BEB):
    • A BEB is an electric bus driven by an electric motor and obtains energy from onboard batteries.
  • Battery Management System (BMS):
    • The BMS is an electronic system that manages a rechargeable battery (cell or battery pack) by protecting the battery from operating outside its safe operating area, monitoring its state, calculating secondary data, reporting that data, and controlling its environment.
  • Bus Rapid Transit (BRT):
    • A BRT is a high-quality bus-based transit system that delivers fast, comfortable, and cost-effective services at metro-level capacities.
  • Behind the Meter (BTM):
    • BTM is a dividing line between power supplied to consumers from a public monopoly utility and energy generated, stored, and used by private consumers.
  • Concession:
    • It is the action by which an administration grants individuals or companies the right to exploit any of its goods or services for a specific period.
  • Decarbonization:
    • It is the conversion to an economic system that sustainably reduces and compensates for carbon dioxide emissions (CO₂).
  • End-of-Life (EOL):
    • EOL stands for End of Life, which is the point when a battery can no longer operate close to peak capacity.
  • Front of the Meter (FTM):
    • FTM refers to any energy generation, storage, or consumption that occurs before electricity reaches a customer’s meter.
  • Lithium-Ion-Battery (LIB):
    • An LIB is a rechargeable battery that stores energy by reversible reduction of lithium ions.
  • State of Charge (SOC):
    • SOC is the charge level of an electric battery relative to its capacity.
  • State of Health (SOH):
    • SOH refers to a battery’s current condition or health status. It provides information about the battery’s overall capacity, efficiency, and ability to deliver its intended performance.
  • Total Cost of Ownership (TCO):
    • TCO is a term that helps stakeholders to analyze a product or service’s indirect and direct costs.
  • Vehicle-to-Grid (V2G):
    • V2G is a technology that enables energy to be pushed back to the power grid from an electric car’s battery.
  • Zero-Emission Bus (ZEB):
    • An ZEB is any transit, tourist, school, military, motor coach, or other type of bus whose primary propulsion and auxiliary power technologies produce zero carbon emissions in daily operation.
