Embodiment Construction

[0028] In particular, with reference to such illustrations, A generally shows an apparatus for recharging a battery of an electric car or similar vehicle.

[0029] The device A comprises switching means which can be connected at the input to the alternating current supply line AC IN and at the output to the high voltage battery HVB and the low voltage battery LVB of the electric vehicle.

[0030] The conversion device can be used to recharge the high voltage battery HVB and the low voltage battery LVB.

[0031] Preferably, the converting means comprises at least one AC / DC converter for converting the electrical signal from the AC power line AC IN into a DC voltage suitable for the operation of the device A, and for switching the high voltage battery HVB and the low voltage battery LVB Recharge.

[0032] According to the invention, the conversion means comprise:

[0033] - Input stage F IN , LIC, PFC / STU, which can be optionally connected to AC power line AC IN or high volta...

Abstract

The appliance (A) for recharging batteries of electric vehicles or the like comprises conversion means connectable at input to an alternating current power supply line (AC IN) and connected at outputto a high-voltage electric battery (HVB) and to a low- voltage electric battery (LVB) of an electric vehicle, the conversion means being activatable for recharging the high- voltage electric battery (HVB) and the low- voltage electric battery (LVB), wherein the conversion means comprise: an input stage (FIN, LIC, PFC / STU) connectable alternatively to the alternating current power supply line (AC IN) and to the high-voltage electric battery (HVB); a first converter (CNVl) having an input connected to the input stage (FIN, LIC, PFC / STU) and an output connected to the high- voltage electric battery (HVB); a second converter (CNV2) having an input connected to the input stage (FIN, LIC, PFC / STU) and an output connected to the low-voltage electric battery; the first and second converter (CNVl,CNV2) being activatable for the simultaneous recharging of the high- voltage electric battery (HVB) and of the low- voltage electric battery (LVB).

Description

technical field [0001] The invention relates to a device for recharging the battery of an electric car or similar vehicle. Background technique [0002] The use of this device is known and common, usually integrated in electric vehicles, suitable for enabling recharging of the battery of the vehicle itself. [0003] like figure 1 As shown, a device of known type comprises a battery charger denoted L1 connected at the input to the AC power line AC IN and at the output to the high voltage battery HVB of the electric vehicle itself. [0004] The battery charger L1 typically includes a first input filter F connectable to the AC power line AC IN IN1 , an inrush current limiter LIC, a power factor correction circuit PFC, a first converter CNV1 of DC / DC converter type and a first output filter F connected to the high voltage battery HVB of the electric vehicle OUT1 . [0005] Therefore, the battery charger L1 is adapted to be connected to the power line AC IN and recharge the h...
