View moreYou can’t always use 100% of energy from a battery without damage. So, depth of discharge gives you a % of how much energy you can use safely.
For example, a 100Ah lead-acid battery at 12V with a 100% state of charge and a 50% DoD limit can run a 120W load for 5 hours. Ampere-hour (Ah): A unit of electric charge. Voltage (V): Electric potential difference or electromotive force. State of Charge (SoC): The current level of charge in a battery as a percentage of its capacity.
So, the battery will last approximately 5 hours under these conditions. Battery runtime refers to the duration a battery can power devices before needing a recharge. This concept is crucial in scenarios where consistent power supply is essential, such as in emergency systems, renewable energy storage, and mobile applications.
Battery Voltage (V): Indicates the electric potential the battery can provide. Common voltages are 12V, 24V, 48V, etc. Battery Capacity (Ah): Represents how much charge the battery can hold. A battery with a capacity of 100Ah can theoretically supply 100A for 1 hour, or 1A for 100 hours, under ideal conditions.
So, yes. Batteries have a max current drain (given by design and physical/chemical limitations) and yes the storage rating (being Ah, Wh or Joules) changes depending on battery design and load applied, and yes Wh is a better way to compare batteries because it takes voltage in account.
As mentioned above, you can charge your battery strategically. GivEnergy home batteries will charge and discharge intelligently by default, taking advantage of cheaper energy rates. However, you can also take a more hands-on approach by setting schedules and timers around your energy usage and lifestyle.
