Abstract

The invention discloses a vehicle and a charging device. The device comprises a charging unit, a voltage feedback unit, a charging line and a charging interface. The charging line is connected with acharging circuit and the charging interface. The voltage feedback unit is connected with the charging unit and the charging interface. The voltage feedback unit is used for detecting the current actual charging voltage of the charging interface, and providing feedback of a voltage drop indication signal to the charging unit if the actual charging voltage is smaller than the reference voltage. Thecharging unit is configured to, after detecting the voltage drop indication signal, in accordance with the voltage drop indication signal, raising the charge voltage to the charge output. The adjustedcharging voltage is utilized to continue supplying power to the charging interface through a charging wire, so that the problem that the charging voltage drops due to the excessive length of a wire harness of the charging interface and the charging interface cannot be charged can be effectively solved, and the length and the diameter of the wire harness and contact impedance energy factors need not to be considered. The charging device is adaptable to all wire harnesses and vehicle models, and is flexible in application.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a charging device and a vehicle with the charging device. Background technique [0002] Currently, most cars come with an on-board USB port that users can use to charge portable devices such as mobile phones or tablets. The power supply of the car USB generally comes from the entertainment navigation host on the car. The connection from the navigation host to the car USB interface is through a wire harness. Generally, the wire harness is relatively long, up to about 3 meters. Since the wire harness itself has impedance, its impedance It is determined by the material, wire diameter and length of the wire harness, generally 200-400mΩ. Most smartphones and tablet computers on the market support high-current charging, and the charging current is above 2.1A. According to Ohm's law, the voltage drop on the wiring harness can be calculated above 0.8V. For example, when the output vol...
