Problems solved by technology

As a result, the system of the '037 patent fails to allow the turbine engine to operate at its maximum efficiency point, and in some cases cannot store all of the excess energy produced by the turbine and / or traction motor as quickly as desired

Embodiment Construction

[0010] figure 1 It is a schematic diagram of a mobile vehicle system including the energy management system according to the present disclosure. in figure 1 In the exemplary embodiment of the mobile vehicle system is depicted as a locomotive 100 configured to run on a track 104. The locomotive may be a diesel electric vehicle running a diesel engine 106 located in the main engine housing 102. However, in alternative implementations of locomotive 100, alternative engine configurations may be adopted, such as gasoline internal combustion engines, gas turbine engines, biodiesel engines, and natural gas engines. It is expected that the vehicle may alternatively be a truck, a bus, a van, a passenger car on the road, and an off-road vehicle (OHV) such as a large excavator, an excavator and dump truck.

[0011] The energy management system of the locomotive 100 may include an energy management controller 116, a first layer of energy storage devices (such as super capacitors and inertia...

Abstract

A method of storing energy produced by a mobile vehicle is disclosed. The method may include receiving information on a vehicle trip profile. An electrical mode of a traction motor configured for propelling the vehicle may be changed from a motor mode where the traction motor receives electrical power to a generator mode where the traction motor produces electrical power when the trip profile indicates a charging opportunity. The method may further include directing energy generated by the traction motor in generator mode to a first tier of one or more energy storage devices with first rate-of-energy-absorption capabilities. A second tier of one or more energy storage devices with second rate-of-energy-absorption capabilities slower than the first rate-of-energy-absorption capabilities may then be charged with energy from the first tier energy storage devices. The charging of the second tier energy storage devices may continue when the traction motor is no longer producing electrical power.

Description

Technical field [0001] The present disclosure relates generally to energy storage, and more particularly to two-tier energy storage for mobile vehicles. Background technique [0002] Modern vehicles (such as locomotives and heavy trucks) are increasingly equipped with renewable energy sources, energy storage devices, and power-consuming equipment. Renewable energy sources, such as traction motors in dynamic braking mode, have the potential to improve the fuel economy and / or other performance characteristics of these vehicles. One problem associated with renewable energy is that the amount and rate of electricity generated can exceed the charging capacity of known battery systems. Therefore, conventional energy management controllers often waste a lot of generated energy by dissipating energy in the form of heat in the resistance grid. [0003] An attempt to improve the efficiency of hybrid vehicles is disclosed in U.S. Patent No. 4,199,037 (the '037 patent) issued to White on Apr...
