12 Volt Battery Voltage Chart

Another important factor that affects the voltage of your battery is the discharge rate. When you use your battery, it discharges, and the voltage drops.

For example, if a 10 kWh battery has a

6 FAQs about [Battery discharge degree]

What is depth of discharge (DOD) of a battery?

The Depth of Discharge (DOD) of a battery determines the fraction of power that can be withdrawn from the battery. For example, if the DOD of a battery is given by the manufacturer as 25%, then only 25% of the battery capacity can be used by the load.

What is the relationship between depth of discharge and battery life?

DOD (Depth of Discharge) is the discharge depth, a measure of the discharge degree, which is the percentage of the discharge capacity to the total discharge capacity. The depth of discharge has a great relationship with the life of the battery: the deeper the discharge depth, the shorter the life. The relationship is calculated for SOC = 100% -DOD

Why does a battery have a depth of discharge?

This occurs since, particularly for lead acid batteries, extracting the full battery capacity from the battery dramatically reduced battery lifetime. The depth of discharge (DOD) is the fraction of battery capacity that can be used from the battery and will be specified by the manufacturer.

How do you calculate the depth of discharge of a battery?

For fully charged batteries, the depth of discharge is connected to the state of charge by the simple formula D o D = 1 − S o C {\displaystyle \mathrm {DoD} =1-\mathrm {SoC} } . The depth of discharge then is the complement of state of charge: as one increases, the other decreases.

What is the discharge characteristic curve of a battery?

The working voltage of the battery is used as the ordinate, discharge time, or capacity, or state of charge (SOC), or discharge depth (DOD) as the abscissa, and the curve drawn is called the discharge curve. To understand the discharge characteristic curve of a battery, we first need to understand the voltage of the battery in principle.

What is the discharge cut-off voltage of a battery?
