A regenerative brake is an energy recovery mechanism which slows a vehicle or object by converting its kinetic energy into a form which can be either used immediately or stored until needed. This contrasts with conventional braking systems, where the excess kinetic energy is converted to unwanted and wasted heat by friction in the brakes. In addition to improving the overall efficiency of the vehicle, regeneration can greatly extend the life of the braking system as its parts do not wear as quickly.

Regenerative braking

  • Sectors
    Objective

    Employing regenerative braking in trains can lead to substantial CO2 emission reductions, especially when applied to full stop service commuter trains (8 – 17%) and to very dense suburban network trains (~ 30%). Regenerative braking applied to freight trains can also lead to CO2 emission reductions, albeit considerably lower than for full stop service trains (~5%). When regenerative braking is employed, the current in the electric motors is reversed, slowing down the train.

    What does India’s Intended Nationally Determined Contribution imply for its approach to climate negotiations? And what implications does it have for domestic development choices?

    This article examines India’s INDC through each lens, to understand the implied logic with regard to India’s complex climate–development choices, and with regard to its strategic international choices.

    It finds that the INDC reflects, as yet, an inadequate consideration of the climate and development linkages that should inform India’s actions.

  • A freewheeling hydraulic Pump/Motor installed between the engine and the gear box is connected to a low pressure hydraulic accumulator on one side and to a high pressure hydraulic accumulator on the other side. 1. The braking and deceleration energy is converted to hydraulic energy and stored in the high pressure accumulator to recycle the energy efficiently . 2.

    To solve any problem, people need knowledge. The knowledge is there somewhere, described in some way, but it is often unavailable to those who need it most.
