Abstract
A method and system of operating an internal combustion engine (ICE) of a hybrid powertrain system for powering a vehicle or stationary apparatus having a variable load demand includes arrangements and configurations of operating the ICE to charge/recharge capacitive energy storage, such as ultra-capacitors, during acceleration or high load demand on the ICE. Operation of the ICE can be transitioned from one mode of operation to another, more efficient, mode of operation during charging and high load. The present invention provides fuel efficiency/economy benefits when charging the capacitive energy storage during high load situations.
Claims26
A method of operating a hybrid power system for powering a vehicle or stationary apparatus having a variable load demand, the method comprising:
- operating an internal combustion engine (ICE);
- and
- operating a generator or electric machine to charge/recharge capacitive energy storage of at least one electrical energy storage device during acceleration or high load demand on the ICE.
A hybrid power system for powering a vehicle or stationary apparatus having a variable load demand, the system comprising:
- an internal combustion engine (ICE) controlled to operate a generator or electric machine to charge/recharge capacitive energy storage of at least one electrical energy storage device during acceleration or high load demand on the ICE.
