Title:
MANUAL VEHICLE WITH AUXILIARY POWER
Document Type and Number:
Japanese Patent JP3688745
Kind Code:
B2
Abstract:
PURPOSE: To provide a manual vehicle with auxiliary power which can perform accurate control, monitoring the battery voltage, and can prevent the overdischarge of a secondary battery or occurrence of memory effect.
CONSTITUTION: This manual vehicle is equipped with a secondary battery 39, which supplies a motor 36 for auxiliary torque with a current, a control means 42, which changes the current of this secondary battery 39, according to the torque, a current detection means 135, which detects the value of a current, a threshold computing means 108, which computes the threshold, based on the current value, and an information means which informs a user of a secondary battery 39 to that effect when the voltage of the secondary battery 39 falls under the threshold. By providing an upper limit on the threshold for the time when the current is not more than the first boundary value, it is so arranged as not to break in the threshold with the sharp drop of the battery voltage immediately after the start of discharge. Moreover, by providing a lower limit on the threshold for the time when the current is not less than the second threshold, it is arranged so that the discharge may not be performed when the battery voltage is extremely low.
