Title:
VEHICLE HYDRAULIC DEVICE WITH BATTERY DEGRADATION DETERMINATION
Document Type and Number:
Japanese Patent JP2017019417
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicle hydraulic device with battery degradation determination capable of avoiding a situation where a vehicle is unable to travel due to degradation of a battery by determining the battery degradation on the hydraulic device side and notifying an operator.SOLUTION: A vehicle hydraulic device with battery degradation determination comprises: a voltage measurement device 20 for measuring an input voltage from a battery BT; a controller 10 having a calculation function and a storage function; and notification means such as an LED 30 for notifying an operator of battery degradation. The controller 10 detects a voltage difference between pre-operation and in-operation of the hydraulic device (an electric motor) measured by the voltage measurement device 20. The controller determines battery degradation when the voltage difference becomes a prescribed threshold value or more, and drives the notification means such as the LED 30.SELECTED DRAWING: Figure 1
