Abstract
A battery charging system for a hybrid electric powerplant can be configured to determine a maximum available charging power available from windmilling and/or excess thermal engine power available, and to use up to the maximum available charging power and/or the excess thermal engine power available to charge a battery. In certain embodiments, a control module can be configured to determine the maximum available charging power available from windmilling.
Claims18
A battery charging system for a hybrid electric powerplant configured to determine a maximum available charging power available from windmilling and/or excess thermal engine power available, and to use up to the maximum available charging power and/or the excess thermal engine power available to charge a battery;
- a control module configured to determine the maximum available charging power available from windmilling, wherein the control module includes a windmilling power available module configured to receive aircraft data and to determine the maximum available charging power available from windmilling.
A control system for charging a hybrid electric vehicle battery, comprising:
- a windmilling power available module configured to receive aircraft data and to determine a maximum available charging power available from windmilling;
- an excess thermal engine power module configured to determine the excess thermal engine power available, and
- a sum block operatively configured to receive the maximum available charging power from windmilling and the excess thermal engine power available, and to output a total charging power available.
A computer implemented method, comprising:
- determining a maximum available charging power available from windmilling;
- determining a total charging power available using the maximum available charging power and an excess thermal engine power available;
- and
- controlling an electric motor to generate electrical power as a function of the total charging power available.
