Embodiment Construction

[0013] figure 1 It is a schematic diagram of the structure of the present invention. refer to figure 1 Specific embodiments of the present invention are described in detail below with specific examples.

[0014] Such as figure 1 What is given is a structural schematic diagram of an on-board charging device for a fuel cell vehicle supercapacitor proposed by the present invention. The on-board charging device for supercapacitors of fuel cell vehicles consists of an input terminal, a 24VDC / 220VAC inverter unit, a rectifier unit, a selection switch, and a charging resistor R 1 ~R 5 , a control unit, a start switch and an output terminal. The input end is used to connect the 24V battery on the car to this device; the input end is connected to the 24VDC / 220VAC inverter unit, and the 24VDC / 220VAC inverter unit inverts the 24V DC power of the 24V battery into 220V, 50Hz AC power; 24VDC / 220VAC inverter The output end of the unit is connected to the rectification unit, which recti...

Abstract

The vehicle-carried charge device for super capacitor of fuel-cell vehicle comprises an input end connected with 24V accumulator on vehicle, and inside connects with in turns 24VDC / 220VAC inverter, a rectifier, a selection switch to select different charge resistance, a start switch to control output state, and an output end on the super capacitor, wherein when the output voltage up to expected value, it sets switch on close state to stop charging.

Description

technical field [0001] The invention relates to a charging device, in particular to a vehicle-mounted charging device for a supercapacitor of a fuel cell vehicle, and belongs to the field of fuel cell vehicle research and development. Background technique [0002] Fuel cell vehicle is a new energy vehicle. Compared with traditional internal combustion engine vehicles, it has excellent performance of energy saving, environmental protection, and quiet operation, so it has become a hot spot in the current new generation of vehicle research and development technology. Supercapacitors are often used as auxiliary power devices for fuel cell vehicles, and battery packs (usually with a terminal voltage greater than 300V) can also be used as auxiliary power devices. [0003] The fuel cell system is the main power source of the fuel cell vehicle, and before each start, the auxiliary power unit is required to provide the electric energy required for starting. At present, for common fu...
