Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] see figure 1 , a battery management system for pure electric buses, the system mainly includes a main control module, a detection module, a handheld device, a monitoring computer and an on-board battery pack. The battery management system for pure electric buses adopts a distributed structure of multiple communication buses, which can realize three working modes, including on-board operation mode, vehicle emergency charging mode and quick replacement mode.

[0025] In practical applications, in order to achieve a certain voltage, power and energy, multiple single cells must be connected in series and used in groups. In a pure electric bus, the on-board battery pack is composed of multiple battery boxes connected in series, and each battery box is composed of multiple single cells connected in series. Each battery box is equipped with 1 detection modu...

Abstract

The invention relates to the technical field of battery management systems for electric vehicles, and provides a battery management system for a pure electric bus. The battery management system has three working modes of on-vehicle running, whole vehicle emergent charging and quick replacing, and mainly comprises a main control module, a detection module, a handheld device, a monitoring computer and an on-vehicle battery pack. The battery management system can transmit the obtained real-time battery state and detailed information on the on-vehicle battery pack after processing to a whole vehicle controller, an on-vehicle instrument, and the monitoring computer for online monitoring; and under the whole vehicle emergent charging and the quick replacing modes, the battery management system can perform data interaction with a charging device to achieve safe charging. The battery management system is also provided with the handheld device, and can achieve voltage acquisition of a single-box battery, and the debugging and the fault diagnosis of the detection module. The battery management system has the advantages of strong communication functions, perfect charging management, complete auxiliary equipment, and high safety, reliability and stability.

Description

technical field [0001] The invention relates to the technical field of electric vehicle battery management systems. Background technique [0002] With the rapid development of the automobile industry and the rapid increase of urban population and vehicles, the fuel consumption of the urban transportation system will also increase sharply, and the pressure on the transportation system is also increasing. The pressure of energy saving and environmental protection is driving the technological change of the transportation energy power system, and the main trend is the electrification of vehicle energy. Due to the fixed bus route and short mileage, the power system is required to have good economical and environmental requirements. At present, the energy density of batteries has basically met the needs of bus operation, and corresponding batteries can be equipped according to the mileage of bus lines. Therefore, pure electric buses are one of the main development directions of e...
