Title:
METHOD AND DEVICE FOR MANAGING THE ENERGY OF A HYBRID VEHICLE
Document Type and Number:
WIPO Patent Application WO/2015/092173
Kind Code:
A3
Abstract:
The invention relates to a method for managing the energy of a hybrid vehicle comprising a heat engine (1), one or more electric traction motors (2), at least one high-voltage traction battery (4), a low-voltage on-board battery (6) for the vehicle accessories (8), a current inverter (3) capable of transforming the DC currents supplied by the traction battery (2) and by the on-board battery (6) into AC currents for the electric motor (2), and a current transformer (7) capable of converting the high-voltage current of the traction battery (4) into low-voltage current of the on-board battery (6), characterised in that the transformer (7) has reversible operation that makes it possible to use the stock of energy available in the low-voltage battery (6) such as not to draw energy from the high-voltage battery (4) when the latter has a relatively low state of charge (SOC).
