How much current should an 80A battery discharge [PDF]

6 FAQs about [How much current should an 80A battery discharge ]

What is a 20 hour battery discharge rate?

This is known as the "hour" rate, for example 100Ahrs at 10 hours. If not specified, manufacturers commonly rate batteries at the 20-hour discharge rate or 0.05C. 0.05C is the so-called C-rate, used to measure charge and discharge current. A discharge of 1C draws a current equal to the rated capacity.

How long can a battery be discharged?

Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.

What is the maximum charge and discharge power of a battery?

The maximum charge and discharge power is 3 kW 2 3 4. Since the capacity of the battery is 75 Ah 2, we need to find the C-rate. One way to do this is to divide the maximum charge or discharge power by the capacity and voltage. This means you should set the charging current and discharge amps to 1.29 amps for this battery.

Can a battery discharge with 2 a?

Note that the highest discharge current that is mentioned is 1000 mA = 1 A. That does not mean you cannot discharge with 2 A but realize that the battery's capacity will be less at such a high current. You will get less energy out of the battery compared to a more realistic discharge current of for example 100 mA.

How much current does a 100 Ah battery draw?

This is usally promised by the manufacturer of the battery. Each 100ah promised by your battery bank is at a 20 hourly rate at 5 amps. The amp-hours drops the greater the current draw. At 5 hours on a 100 a-h battery for example you might get 82a-h at 16 amps. The manufacturer will give you a table on this.

What is a good battery discharge rate?

Battery manufacturers rate capacity of their batteries at very low rates of discharge, as they last longer and get higher readings that way. This is known as the "hour" rate, for example 100Ahrs at 10 hours. If not specified, manufacturers commonly rate batteries at the 20-hour discharge rate or 0.05C.
