Device for fuel-saving through electrical energy management controls load(s) so electrical load and/or generator power increases in high engine efficiency states; in low efficiency states load(s) is controlled to reduce load/generator power

摘要

The device has a controller (6) with an algorithm for electrical energy management, a sensing arrangement (9) for detecting different driving states, at least one controllable load (5) and a generator (1) with a generator output voltage regulator(2). At least one load is controlled so that the electrical load power increases and/or the generator power increases in driving states with high internal combustion engine efficiency. In low efficiency states at least one load is controlled so the load and/or generator power reduces. An independent claim is also included for a method of conducting electrical energy management.
