Electric drive braking energy recovery mining vehicle

Abstract

The present invention discloses an electrically driven braking energy recovery mine vehicle. The mine vehicle comprises an overall vehicle control system disposed on the vehicle, a driver input system, an electrically driving and energy recovery controlling system used to drive the vehicle and perform energy recovery when braking the vehicle, a battery managing system capable of charging and discharging, and a braking system capable of braking the vehicle. The overall vehicle control system is, through a data bus, connected to the driver input system, the electrically driving and energy recovery controlling system, the battery managing system and the braking system. The battery managing system provides electric power to the electrically driving and energy recovery controlling system. The electrically driving and energy recovery controlling system charges the battery managing system. The electrically driven mine vehicle of the present invention is powered by a storage battery set for operation, and has an energy recovery function at the same time. Therefore, the operating cost is reduced and an energy saving effect is realized.

Description

technical field [0001] The present invention relates to an electrically driven braking energy recovery mining vehicle, in particular to a purely electric driving braking energy recovery mining vehicle used in open-pit mines, large-scale hydropower, and infrastructure construction sites. Background technique [0002] Mining vehicles are mainly used in open-pit mines, large-scale hydropower, infrastructure construction sites, earthwork, and ore material transfer. Currently, the vehicles in use are mainly divided into two categories: one is a mining vehicle powered by an internal combustion engine and fully mechanically driven, and the other is a The first type is powered by an internal combustion generator set and has a full electric drive mining vehicle. However, when the above two transport vehicles are running on an unloaded uphill and full-load downhill working condition, the kinetic energy and potential energy they have are dissipated into the air by the heat generated by...

Problems solved by technology

However, when the above two transport vehicles are running on an unloaded uphill and full-load downhill working condition, the kinetic energy and potential energy they have are dissipated into the air by the heat generated by the friction of the brakes of the vehicle, causing pollution to the environment and generating thermal effects; at the same time Regardless of whether it is mechanical transmission or full electric drive, the internal combustion engine will cause serious air pollution. In addition, due to the increase in fuel prices, the operating costs of internal combustion engine-driven transport vehicles continue to increase
