8.3.6 Changing to Floating Charge etc. (for MSE individual battery)

Table 8.7 shows the procedure used to change manually from protective charge to floating charge.

This operation does not apply to shared battery systems.

(1)An MSE battery normally operate in floating charge mode.

(2)To prevent the battery temperature from rising, the mode changes automatically to protective charge mode when a "BATT FAULT1" (BATTERY OVER TEMP.) warning occurs.

(3)In protective charge mode, the battery is automatically charged at a voltage about 5% lower than normal (floating) charge when the battery temperature has risen above the rated value, in order to prevent deterioration caused by excessive charging at high temperatures.

(4)After a set amount of time has elapsed (about 6 hours), if the "BATT FAULT1" (BATTERY OVER TEMP.) warning message has disappeared, the mode will automatically change back to floating charge. As a result, it will not normally be necessary to change the mode manually as described below.
