Embodiment Construction

[0017] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] An embodiment of a battery equalization opening method for a dual-source trolleybus of the present invention:

[0019] Such as figure 2 As shown, the network cable and the isolated DC-DC are connected through the collector pole, the isolated DC-DC and the battery management system are connected through the CAN network, between the power battery slave board and the battery management system, and between the battery management system and the vehicle controller , Between the vehicle controller and the instrument, the vehicle controller and the isolated DC-DC are all connected through CAN, and the factory line network and station identification are connected and interacted with the vehicle controller through sensors.

[0020] When the vehicle enters the bus station, as long as the vehicle does not turn on the ignition, the line-network ...

Abstract

The invention relates to a whole vehicle controller of a dual-source trolley bus and a battery equalization starting method. The invention does not adopt a BMS to judge whether the battery equalization charging is turned on, but judges whether the equalization identification bit is valid according to a vehicle field station mark, a network hanging signal and a vehicle speed by the whole vehicle controller, and when the equalization identification bit is valid, the battery equalization is turned on. At the same time, it can ensure the consistency of vehicle condition and the safety of driving.When the balancing effect is achieved.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to a vehicle controller of a dual-source trolleybus and a battery equalization opening method. Background technique [0002] Pure electric buses apply electric drive technology, which meets the needs of energy conservation and environmental protection, but short driving range, large-capacity batteries and infrastructure costs of charging stations restrict their development. The trolley bus can realize the pure electric driving of the vehicle on the grid, but it is highly dependent on the wire network, and the inability to operate off the grid also restricts its development. Therefore, dual-source trackless pure electric vehicles that combine line grid energy or other energy with pure electric battery energy have attracted much attention. The dual-source trolleybus can run away from the trolleybus grid. It is driven by the on-board power supply in the section without ove...
