Abstract

The invention discloses an integrated device for forklift power battery modularization. The integrated device comprises a controller assembly and a battery cell module assembly, the controller assembly comprises a controller shell structural member, a display system wire harness, a controller low-voltage wire harness, a controller high-voltage wire harness, a BMS module and a DC-DC unit. The display system wire harness, the controller low-voltage wire harness and the controller high-voltage wire harness are arranged on the outer side wall of the controller shell structural member. A forklift power battery system is divided into two independent units, namely a battery cell module system assembly and a control system assembly, the control system assembly includes: a BMS module, a PRA relay system, an internal high-voltage bus, a DC-DC unit, an internal low-voltage wire harness and a connector assembly, an external high-voltage wire harness and a connector assembly, and an auxiliary functional part. The battery systems with different voltage and energy requirements are completed through the matching of the corresponding number of module systems and control systems, so that the development of a plurality of battery systems is avoided, and the cost and the labor cost of the development process are reduced.

Description

technical field [0001] The invention relates to the technical field of power battery systems for electric forklifts, in particular to a modular integrated device for power batteries of forklifts. Background technique [0002] In the design of the forklift power battery system, the existing method is to use a corresponding integrated solution for each type of forklift. The system includes the battery module system, the shell structure system, the BMS control system, and the PRA relay assembly. system, DC-DC unit, auxiliary function parts, high and low voltage wiring harness, connector system, etc. One type of battery system corresponds to one type of forklift. For multiple forklift projects with different voltage and energy requirements, it is necessary to develop multiple battery systems. The overall mass production and development process is expensive and labor-intensive, and the cycle is long. Therefore, it is necessary to design a modular integrated device for power batt...
