Abstract

The invention provides a battery switching system for an unmanned vehicle. The system is applied to an automatic driving vehicle or an unmanned vehicle and comprises two battery systems and a control unit, the two battery systems are used for sequentially supplying high-voltage power to the unmanned vehicle, and each battery system comprises a blocking diode; when any one of the two battery systems is in a power supply state, if the electric quantity of the current power supply battery system is lower than a preset threshold value and the electric quantity of the other battery system is higher than the other preset threshold value, the control unit controls the other battery system to be started, and the current power supply battery system and the other battery system supply power to the unmanned vehicle at the same time; at the moment, the blocking diode can prevent the other battery system from charging the current power supply battery system, and after the power supply state is maintained for a preset time, the control unit closes the current power supply battery system to complete switching between the two battery systems. According to the invention, automatic battery replacement of the unmanned vehicle is realized, the battery replacement cost and time consumption are reduced, and the battery replacement efficiency is improved.

Description

technical field [0001] The present disclosure relates to the field of unmanned driving technology, and in particular, to a battery switching system for unmanned vehicles. Background technique [0002] Unmanned vehicles, also known as autonomous vehicles, unmanned vehicles or wheeled mobile robots, are integrated and intelligent technological products that integrate environmental perception, path planning, state recognition and vehicle control. The power is usually provided by the drive motor, and the energy comes from the lithium battery. At present, due to the limitation of charging piles, the on-board charging of unmanned vehicles is very inconvenient, and the on-board charging time is long, which affects the operation time. Therefore, the energy supply problem of the unmanned vehicle can be solved by switching the battery system (ie, battery swapping). [0003] At present, the battery switching system of unmanned vehicles mainly includes the following two switching meth...
