Battery pack information display device and method

Abstract

The invention discloses a battery pack information display device, which comprises a power supply, a voltage conversion module, a CAN receiving circuit, a single chip microcomputer, an interface conversion circuit and a serial port display screen, wherein the power supply is respectively connected with the voltage conversion module and the serial port display screen; the voltage conversion moduleis respectively connected with the CAN receiving circuit, the single-chip microcomputer and the interface conversion circuit; the serial port display screen is connected with the interface conversioncircuit; the interface conversion circuit is connected with the single-chip microcomputer; the single-chip microcomputer is connected with the CAN receiving circuit; and the CAN receiving circuit is used for receiving CAN signals sent by a battery pack. The beneficial effects are that the CAN signals are analyzed through the single-chip microcomputer, the analyzed battery information data is transmitted to the serial port display screen to be displayed, the state information of the battery pack can be comprehensively reflected, hardware of the original battery pack is not changed, the redevelopment of a BMS is avoided, the cost is saved, only the CAN signals are analyzed, programs are designed in a modular mode, the structure is simple, and the expansion is easy.

Description

【Technical field】 [0001] The invention relates to the technical field of batteries, in particular to a battery pack information display device and method. 【Background technique】 [0002] At present, many electric forklifts only have power display. Usually, the current battery power and fault status are determined by the number of LEDs on and off. Users cannot obtain detailed information about the battery status. Some electric forklift battery packs that use LCD screens usually need to redevelop the BMS, use the BMS to drive the LCD screen to display battery information, and the software also needs to rewrite the display driver. The cost of the product is reduced, and there is no way to carry out secondary development of the software of BMS from different manufacturers, so the gradient utilization scenarios of BMS and power battery are limited. Some current LCD screens require program drivers to realize screen and text display, which is complicated to develop, has many hardw...

[0002] At present, many electric forklifts only have power display. Usually, the current battery power and fault status are determined by the number of LEDs on and off. Users cannot obtain detailed information about the battery status.

Some electric forklift battery packs that use LCD screens usually need to redevelop the BMS, use the BMS to drive the LCD screen to display battery information, and the software also needs to rewrite the display driver. The cost of the product is reduced, and there is no way to carry out secondary development of the software of BMS from different manufacturers, so the gradient utilization scenarios of BMS and power battery are limited

Some current LCD screens require program drivers to realize screen and text display, which is complicated to develop, with many hardware interfaces and high cost
