Energy management system and energy control method for trolleybuses

Abstract

The invention discloses an energy management system and an energy control method for trolleybuses, and relates to the field of double-source trolleybus control technologies. The energy management system comprises a motor, a DC-DC converter, a battery, a cloud server, a controller, a positioning module and a wireless communication module, wherein the DC-DC converter and the battery are connected with the motor. By collecting network voltage information, trolleybus position information, battery electric quantity information and motor power information, performing calculation and analysis through the cloud server, instructing the DC-DC converter and deploying trolleybus online network segments, the collective shutdown problem is solved.

Description

technical field [0001] The invention relates to the technical field of dual-source trolleybus control, including an energy management system, which collects grid voltage information, vehicle position information, battery power information and motor power information, stores and controls DC / DC converters to provide energy; and also includes trolleybuses The energy control method of the company uses computers to establish analysis strategies, control the position of vehicles, and distribute energy efficiently. Background technique [0002] Under the serious situation of increasing urban air pollution and increasing dependence on foreign oil, traditional fuel-powered buses can no longer meet the needs of energy conservation and emission reduction. The country has begun to vigorously promote new energy buses. Buses driven by pure electricity require very expensive car purchase and maintenance costs, while dual-source trolleybuses not only overcome the inherent defects of ordinar...

Problems solved by technology

[0004] However, its shortcoming is that when dual-source trolleybuses connected to the power grid appear together in a certain section of the power grid due to traffic conditions and other reasons, their energy demand for the power grid will be much higher than the load capacity of the power grid, causing the voltage of the power grid to drop, resulting in The grid energy cannot be effectively transmitted to the motor system of the dual-source trolleybus, so that the motor cannot normally drive the vehicle to start and run, and in severe cases, the phenomenon of vehicles collectively lying down

[0005] When the existing dual-source trolleybuses face the phenomenon of collective lying down, they can only forcibly disconnect some dual-source trolleybuses from the power grid to ensure that the limited energy of the power grid can be transmitted to the dual-source trolleybuses that are in urgent need of energy. Whether to disconnect the power grid, when to disconnect the power grid, and when to reconnect the power grid requires communication and coordination between the driver and the driver, thereby reducing the operating efficiency of the dual-source trolleybus and increasing the workload of the driver
