When a battery is connected to an external electric load ...
3. Charge and discharge rates. A battery''s charge and discharge rates track how much electricity it can take in and send elsewhere, per hour. These rates are measured in kilowatts (kW), rather than kWh like a battery''s storage capacity, and affect how many appliances in your home you can run with your battery alone.
When planning or troubleshooting your power needs you may have come across the idea of battery depth of discharge (Battery DOD). Find out what it means and why it matters. ... A high DOD allows for more of the battery''s energy to be used before needing to be recharged, but it can also reduce the number of recharge cycles of the battery ...
The depth of discharge is a percentage of the electrical energy that can be withdrawn from the battery relative to the total battery capacity. For example, if you discharge 8 kWh from a solar battery with a 10 kWh capacity, the battery''s depth of discharge would be 80% (8 kWh / 10 kWh).
