6 FAQs about [Parameterized forced battery discharge]
What does forced charge/discharge mean?
Indicates the charged and discharged duration. This parameter cannot be set. Forced charge/discharge is used to test the battery connected to an inverter. In normal cases, you are advised not to set forced charge/discharge. The TOU mode is recommended if you want the battery to be charged and discharged in fixed periods for a long time.
Should I set forced charge/discharge mode?
In normal cases, you are advised not to set forced charge/discharge. The TOU mode is recommended if you want the battery to be charged and discharged in fixed periods for a long time. When your phone is connected to a network, on the connection screen, tap in the upper right corner, and then choose File download.
How do I set a battery charge & discharge mode?
Choose Maintenance > Battery maintenance > Forced charge and discharge , set forced charge and discharge parameters, and tap Submit. Specifies whether to charge or discharge the battery. Specifies the forced charge/discharge power. Set the charge and discharge mode. Sets the charge and discharge duration.
What is battery discharge power?
Discharge Power is the rate at which the battery will be discharged while a Discharge Period is is in force and the charge level is above the highest limit which applies. [This can be modified by the Remote Control parameter Battery Discharge power %, but we shall ignore this.]
Can a battery charge while a charge period is in force?
While a Discharge Period is in force, the battery cannot charge and the only discharging which takes place is that specified for the Discharge Period. Outside Discharge Periods (and also Charge Periods which are in force) the system remains in Eco Mode.
Why is a higher charge/discharge rate important?
This enhancement in performance facilitates the attainment of higher charge/discharge rates. However, the considerable heat loads caused by higher currents significantly amplify the risks of over-temperature operation and thermal hazards of battery systems .
