Title:
ELECTRIC FORKLIFT
Document Type and Number:
Japanese Patent JP2015000778
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To achieve an energy conservation of a forklift.SOLUTION: Electric power conversion systems 100, 200, 300 drive motors M1, M2, M3. A controller 810 receives control command values S1 to S3 from an operation system, and executes an arithmetic processing for controlling the electric power conversion systems 100, 200, 300. The controller 810 is so configured as to include at least one of MPU 912 and FPGA 914. A clock generating circuit 920 generates a clock CK which is supplied to the controller 810. The clock generating circuit 920 decreases a frequency of the clock CK in comparison with a usual value, when the state such that a secondary battery is charged by an external power source is detected.
