が防止される。After the start of charging (t = 0), charging is performed with the initial charging current (I 0 = 1.2A), and at the same time, the charging indicator light indicating that charging is in progress is turned on. Constant voltage control is performed from the time (t = t 1 ) when the battery voltage reaches 14.7 ± 0.15V (25 ° C) (Note that this control voltage value is approximately the same as the conventional constant voltage charging method with respect to ambient temperature. -4mv / ℃ ・ with temperature gradient of cell) At this time (t ~
From t 1 ), the charging current I begins to decline, and when it falls to 0.20 A or less (t = t 2 ) is detected, it is charged for 30 minutes with constant voltage (supplementary charging; 10 to 2% of the storage battery capacity is charged. Do). Charge is paused here for 1 minute, and the battery open circuit voltage is measured during this period. If this value is 13.0 ± 0.15V or higher, it is determined that the battery has been charged, and the charging indicator lamp is turned off.
0 minutes constant voltage charging (supplementary charging; 5 to 1% of storage battery capacity)
(Charged for a minute) and then stop charging. This makes it possible to prevent overcharging due to long-time charging. On the other hand, the battery open-circuit voltage value after suspension is 13.0 ± 0.15V
If it does not satisfy the above condition, charging is stopped for 1 minute after supplementary charging with the charging indicator light turned on as shown in Fig. 2, until the battery open circuit voltage value reaches 13.0 ± 0.15V, After supplementary charging → charging pause for 1 minute → battery open-circuit voltage measurement is repeated up to 10 times, the charging indicator is turned off and supplementary charging is performed once to stop charging.
This extends the charging time and prevents insufficient charging. In addition, supplementary charging → charging pause for 1 minute → battery open-circuit voltage value is 13.0 ± 0 even if battery open-circuit voltage is measured 10 times.
If the voltage is less than 15V, the storage battery abnormality indicator light on the charger side is turned on and charging is stopped to prevent continuous charging of the abnormal battery.
