6 FAQs about [Calculate the battery continuous discharge power]
How do you calculate continuous discharge current in a lithium-ion battery?
To illustrate how this formula works in practice, let’s consider a hypothetical scenario where we have a lithium-ion battery with a capacity of 2000mAh (or 2Ah) and a C rating of 20C. Applying the formula I = Capacity x C rating, we can calculate that the continuous discharge current would be: I = 2Ah x 20C
How do you know if a battery has a Max discharge current?
There is no generic answer to this. You read the battery datasheet. Either it will tell you the max discharge current, or it will tell you the capacity at a particular discharge rate, probably in the form C/20 where C means the capacity. You know the current you need : 4.61A.
What is a maximum continuous discharge current?
Maximum Continuous Discharge Current – The maximum current at which the battery can be discharged continuously. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
How do you calculate battery charge/discharge rates?
The battery charge/discharge rates are measured in current (A). To work out the maximum charge/discharge power of the battery you will multiply this current (A) by the BMS voltage. The BMS voltage of a battery will vary between make/model/manufacturer so always refer to your batteries datasheet/manual for the correct current and voltage limits.
What is the relationship between battery capacity and discharge current?
Capacity represents the total amount of charge stored within a battery, while the discharge current dictates how quickly this charge can be released. The relationship with C rating lies in defining how much current can be safely drawn from the battery over time.
How do I set the charge/discharge current for the batteries?
You set the charge/discharge current for the batteries on the inverter in the battery setup page of the settings menu. The Sunsynk 5.12/5.32kWh batteries have a capacity of about 100Ah and a 50A continuous charge/discharge current so you can set the capacity charge and discharge using these values.
