Battery cooling system of electric mining dump truck and control method

Abstract

The invention provides an electric mining dump truck battery cooling system which comprises at least two cooling units arranged in parallel, at least two battery packs arranged in parallel, a first cooling pipeline and a second cooling pipeline, and each battery pack comprises at least two battery units arranged in parallel. Each battery unit comprises at least two battery modules which are connected in series; the water outlets of the at least two cooling units are converged and then communicated with the first cooling pipeline, the water inlets of the at least two cooling units are converged and then communicated with the second cooling pipeline, and the water inlets of the at least two battery units in each battery pack are converged and then communicated to the first cooling pipeline; and the water outlets of the at least two battery units in each battery pack are converged and then communicated to the second cooling pipeline. The invention further provides a battery cooling control method of the electric mining dump truck.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a battery cooling system and control method of an electric mining dump truck. Background technique [0002] With the gradual scale and specialization of mine mining, the requirements for the quality of vehicle transportation are also gradually increasing. At present, the main transportation machinery is mainly mining dump trucks. Mining dump trucks have three major pain points: high fuel consumption, low transportation efficiency, and high environmental pressure. Among them, fuel consumption accounts for more than 50% of the vehicle's operating costs. High fuel consumption has become a heavy burden on the mining transportation industry. Therefore, electric mining dump trucks With its advantages of "high efficiency, energy saving, zero pollution and zero emission", it has gradually become the first model in the mining transportation industry. [0003] The power batte...

Problems solved by technology

[0004] The disadvantages of the existing technology such as the side-mounted battery-type electric mining truck battery cooling system disclosed in Patent No. CN202022436401.5 are: 1. Two cooling units are used to cool a group of battery packs separately, not only the number of pipelines is too large, It is difficult to arrange, and it is easy to cause uneven cooling of each battery module, which affects the safety and service life of the battery; 2. There is no filter in the cooling pipeline, which cannot filter the pipeline and coolant impurities, which may easily cause pipeline blockage; 3. Cooling The pipeline is not equipped with a coolant quick release device, the maintenance of the cooling system is inconvenient, a waste of time, and affects the attendance of the mine car
