Abstract

The invention discloses a new energy electric vehicle super capacitor charging device which comprises a main control chip. The main control chip is connected with a power supply bus through an input isolation switch circuit; the input isolation switch circuit is connected with an input voltage feedback circuit; the input voltage feedback circuit is connected with an input current detection circuit; and the input current detection circuit is connected with a bidirectional BUCK-BOOST converter. The bidirectional BUCK-BOOST converter is connected with an output current detection circuit; the output current detection circuit is connected with an output voltage feedback circuit; and the output voltage feedback circuit is connected with a super capacitor through an output isolation switch circuit. The input voltage feedback circuit, the input current detection circuit, the bidirectional BUCK-BOOST converter, the output current detection circuit, the output voltage detection circuit and the output isolation switch circuit are all connected with the main control chip. A super capacitor charging circuit with a buck-boost function is formed, power optimization is carried out on a charging scheme through internal digital logic, and the functions of simplifying the circuit and reducing the cost are achieved.

Description

technical field [0001] The invention relates to the technical field of charging circuits, in particular to a supercapacitor charging device for new energy electric vehicles. Background technique [0002] New energy electric vehicle (BEV) refers to a vehicle that is driven by a vehicle-mounted power supply and driven by a motor to drive the wheels, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. The charging technology of new energy electric vehicles is particularly critical. The energy recovery of existing charging devices is not sufficient, and the converter is large in size, so it cannot recover electric energy during the braking process of the vehicle. Contents of the invention [0003] Aiming at the above-mentioned shortcomings of the prior art, the present invention provides a new energy electric vehicle supercapacitor charging device capable of...
