What is Efficacy?
Efficacy is the effectiveness of a received charge amount relative to the charge limit, calculated as Charge Amount / Charge Received. For a battery, the charge limit is 1% of its capacity.
Efficacy varies based on the charge received compared to the maximum possible charge, with examples demonstrating how efficacy decreases as the received charge exceeds the battery's charge limit.
Examples of Charge Efficacy using 1000W Battery
Example I:
Given 1000W Battery
When receiving 500W charge
Then maximum charge is 10W
And efficacy is 2%
Example II:
Given 1000W Battery
When receiving 100W charge
Then maximum charge is 10W
And efficacy is 10%
Example III:
Given 1000W Battery
When receiving 10W charge
Then maximum charge is 10W
And efficacy is 100%
Example IV:
Given 1000W Battery
When receiving 5W charge
Then maximum charge is 5W
And efficacy is 100%
