Forklift battery pack parameter display system

Abstract

The invention relates to the technical field of electric forklift battery pack equipment, in particular to a forklift battery pack parameter display system, comprising a power converter electrically connected with the power output terminal of the electric forklift battery pack. The conversion power output terminal of the power converter is electrically connected with a display device, a display controller, an alarm device and a keyboard respectively. The display controller is electrically connected with the display device, the alarm device, the keyboard and the CAN bus which is used for communicating with the power manager respectively. According to the forklift battery pack parameter display system disclosed by the invention, the voltage of the storage battery is converted to power supplyfor an electric device by arranging a power converter, and meanwhile, the system is dormant and awakened through the keyboard, so that the low power consumption characteristic of the whole system isensured. The communication between the display controller and the power manager is achieved through the CAN bus, and the communication protocol follows the CAN 2.0A or the CAN 2.0B, so as to ensure the real-time performance of the communication and the strong anti-electromagnetic interference characteristic.

Description

technical field [0001] The invention relates to the technical field of electric forklift battery pack equipment, in particular to a forklift battery pack parameter display system. Background technique [0002] With the continuous increase of vehicle ownership, the consumption of traditional petrochemical energy is increasing day by day, causing serious environmental pollution problems. Petroleum is a short-term non-renewable resource. With the increase of usage and the reduction of reserves, the supply will become increasingly tight and the price will continue to increase. This will limit the development of a series of industries that use traditional petroleum as energy. The status quo of energy development in the world today has spawned many new energy products, which are actually applied to a wide range of transportation demand markets. The country's strong support and the growth of market demand have promoted the leapfrog development of my country's lithium battery econo...

AI Technical Summary

Problems solved by technology

In some special operating occasions such as indoor warehouses, clubs, halls, etc., the noise and exhaust gas emitted by traditional engines do not meet special requirements, and low-noise, green and environmentally friendly pure electric forklifts are also required.

[0004] At present, the main problems of the system used to display the parameters of the forklift battery pack are: the system does not have the sleep function, and is always in the working state, which leads to the disadvantage of high power consumption; the communication performance between the display system and the battery management machine is poor , the signal transmission has a delay, and the anti-interference ability of the communication is poor; at the same time, the display system does not have an alarm function
