This invention discloses a
State of Charge (SOC) display
system and method for unmanned logistics vehicles, belonging to the field of battery management technology for unmanned vehicles. The
system includes: a vehicle controller, relays, a gateway, and a battery
management system. When the vehicle controller and battery
management system receive
fast charging / slow charging / driving signals, the
relay switches close, the gateway starts working, and forwards the data to the backend
management system. When the vehicle controller and battery management
system receive a driving
signal, the backend management system displays the current SOC and driving status. When the vehicle controller and battery management system receive
fast charging / slow charging signals, the backend management system displays the current SOC, charging status, charging time, and estimated full charge time. If the
fast charging / slow charging / driving
signal is lost, the backend management system displays the last received SOC and the vehicle's offline status, flexibly displaying information such as vehicle SOC, vehicle status, charging time, and estimated full charge time, achieving visualized monitoring of vehicle status and the charging process.
