Abstract

PURPOSE:To easily estimate the remaining capacity of a lead storage battery at an early stage by grasping the short time recovery voltage directly after the discharge of a closed type lead storage battery is stopped, so as to estimate the remaining capacity of the battery. CONSTITUTION:When a charge is input into a lead storage battery 2, voltage drop is generated. When the charge is cut thereafter, terminal voltage is started, and a recovery state is achieved, in which, i.e., in the middle of the recovery in the short time, there is a capacity estimation point 4 (0.1 second after) for estimating the remaining capacity of the storage battery 2. A correlation diagram of the discharge state (%) of the battery 2 as well as the recovery voltage (V) after 0.1 second, with regard to the capacity estimation point 4 is primarily formed, for example, at every installation period of the battery 2. When the remaining capacity of the battery 2 is required, the recovery voltage at the capacity estimation point 4 is measured, and by determining the lead storage battery discharge state (%) at the position of the recovery voltage on the characteristic line correspondent to the installation period of the battery 2, the remaining capacity thereof can be estimated.

This figure shows the recovery characteristics of the terminal voltage immediately after the 1C discharge is stopped. As shown in the figure, the lead-acid battery is normally in a floating charging state or an open state 3, but when a load is actually applied, a voltage drop occurs in the lead-acid battery. After that, when the load is cut off, the terminal voltage rises as shown in the figure, and the battery enters a recovery state. During the short period of recovery, there is a capacity estimation point 4 at which the remaining capacity of the lead-acid battery can be estimated.
