Problems solved by technology

[0002] Electric mixer truck is a kind of engineering vehicle used to transport concrete. In order to achieve environmental protection and energy saving, pure electric mixer trucks have been launched on the market; Power battery packs, however, at present, charging facilities are lacking in most areas of the country, so it is very likely that there will be a lack of electricity on the road and it will not be possible to drive to the charging station. What is more serious is that the concrete in the mixing drum will congeal, and the cleaning work will take a lot of manpower and time

Abstract

The invention provides an electric concrete mixer and a control method thereof. The control method comprises the following steps of acquiring the residual electric quantity of a battery pack; judgingwhether the residual electric quantity is smaller than a first threshold value or not; starting a range extender to charge the battery pack or supplying power to a driving motor if the residual electric quantity is smaller than the first threshold value. According to the technical scheme of the control method of the electric concrete mixer, the configuration of the battery pack is effectively reduced, and the structure of the electric concrete mixer is simplified, the cruising ability of the electric concrete mixer is guaranteed, the situation that the concrete mixer is broken down and a mixing drum stops rotating is avoided, emission is reduced, and pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an electric mixer truck and a control method thereof. Background technique [0002] Electric mixer truck is a kind of engineering vehicle used to transport concrete. In order to achieve environmental protection and energy saving, pure electric mixer trucks have been launched on the market; Power battery packs, however, at present, charging facilities are lacking in most areas of the country, so it is very likely that there will be a lack of electricity on the road and it will not be possible to drive to the charging station. What is more serious about the truck is that the concrete in the mixing drum will congeal, and the cleaning work will take a lot of manpower and time. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] In view of this, an object of t...
