I''m trying to calculate the power of a motor as the battery discharges, and how much difference that does do the power. I have a varying discharge current from 0-20 A, so ideally I''m trying to find some simpler models for the current voltage depending on discharge current and capacity left.
In most substations, the 8-hour rate of discharge is the standard. It gives operators a solid 8-hour window to sort out any AC power supply issues before everything goes haywire. The battery will be rated 125V DC nominal and have an amp-hour capacity rated for this 8-hour rate of discharge.
In most substations, the 8-hour rate of discharge is the standard. It provides operators with a solid 8-hour window to address any AC power supply issues before they become critical. Important Note: We'll be using the IEEE Standard 485 for our substation battery sizing calculation, which helps define DC loads and size lead-acid batteries.
To size a flooded cell, lead-acid battery for a substation, we'll use a 125V DC nominal battery with an amp-hour capacity rated for an 8-hour rate of discharge. This is the standard in most substations.
Substations rely on batteries to ensure their essential operations can function around the clock. This is because the primary AC power supply can be unreliable. If a transmission line or power source goes down, we could lose power entirely.
The primary role of the substation battery system is to provide a source of energy that is independent of the primary ac supply, so that in the event of the loss of the primary supply the substation control systems that require energy to operate can still do so safely.
The anticipated life span of a 48V bank featuring lead-calcium batteries is 20 years. For more information about substation batteries, please contact [contact information].

More than 100,000 substation battery installations in the US represent a strategic investment for utilities. These batteries are typically drawn upon to provide power to switching components and to power the substation control equipment in times of AC power loss.
Depth of Discharge (DoD) measures the energy a battery has used. For example, if you have a fully charged battery rated at 100 Ah and used 40 Ah, your DoD is 40%. The state of Charge (SoC) indicates how much energy remains available in the battery at any given time. Using the previous example, if you have used 40 Ah from your fully charged 100 …

Heat is generated from other than effective power. Effective power is used to drive the load. Thus, "4.2V * 3A * 30/60h" is a straight calculation of (though need some more considerations) power we are drawing from the battery, but not the power to generate heat. Heat is generated from "inefficiency", offset to an ideal power source.
