Abstract
An installation and a method for charging an electric battery for an electric vehicle. The electric vehicle comprises an on-board computer. The installation comprises a main power source delivering a charging power Pc1. The charging method comprises the step of determining the charging power Pc to be delivered to the electric battery in relation to a charging voltage and/or current set point demanded at an instant t by the onboard computer. The charging power is compared against the charging power Pc1 delivered by a main power source. If Pc>Pc1, at least one auxiliary power source delivering a charging power Pc2 is utilized in addition to the main power source such that the sum of the charging powers delivered by the power sources is equal to the charging power Pc.

24. A charging installation for an electric battery of a vehicle, comprising:
-
a main power supply source capable of delivering a charging power Pc1; a first circuit for converting a supply current or voltage delivered by the main power supply source into a charging current or voltage for the electric battery; at least one auxiliary power supply source capable of delivering a charging power Pc2; at least one second circuit for converting a supply current or voltage delivered by the auxiliary power supply source into a charging current or voltage for the electric battery, said at least one second circuit being connected in parallel to the first circuit; and a management system controlling and activating said at least one auxiliary power supply source when a charging power Pc required to charge the battery is greater than the charging power Pc1 delivered by the main power supply source. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)

42. A method for charging an electric battery for a vehicle comprising an onboard computer, comprising the steps of:
-
determining a charging power Pc delivered to the electric battery of the vehicle, during a DC voltage charge of the electric battery, relative to a charging set point demanded at an instant t by the onboard computer; comparing the charging power Pc to the charging power Pc1 delivered by a main power supply source; if Pc>
Pc1, delivering a charging power Pc2 from at least one auxiliary power supply source to supplement the main power supply source, such that the sum of the charging powers delivered by the power supply sources is equal to the charging power Pc. - View Dependent Claims (43, 44, 45, 46)
