14.3.6 Changing to Float Charge from Protection Charge (If applicable)

Table 19 shows the manual procedure to change from protection charge to float charge. This operation applies to batteries which needs protection charge when over temperature.

(1)The battery is normally being charged at float charge mode.

(2)To prevent the battery thermal runaway, this mode will automatically be changed to protection charge when a "BATT FAULT1" (Battery over temperature) warning occurs.

(3)In protection charge mode, the battery is automatically charged at a voltage about 5% lower than float charge.

(4)If the "BATT FAULT1" warning message goes away and a programmed duration is elapsed (about 24 hours), this mode will automatically be changed back to float charge. So, it is not usually required to change the recharge mode manually back to the float charge.
