Choosing power supply, how to get the voltage and current
A constant-voltage supply doesn''t determine the current: the load, which in this case is the device, does. If Johnny wants to eat two apples, he''s only going to eat two whether you put 2, 3, 5, or 20 apples on the table. A device that wants 2 A of current works the same way. It will draw 2 A whether the power supply can only provide the 2 A, or whether it could have supplied 3, 5, or

6 FAQs about [Connect the lead-acid battery to a constant current and constant voltage power supply]
How to charge a lead acid battery?
Charging of a lead acid battery can be done in various ways: Constant voltage charging is most commonly used for a sealed lead acid battery. The initial charging current in a constant voltage battery charger is limited by a resistor. Figure 1 below shows the charging over time for a constant voltage charger. Figure 1 Credit BB Battery
How to charge a valve-regulated lead-acid battery?
For charging the valve-regulated lead-acid battery, a well-matched charger should be used because the capacity or life of the battery is influenced by ambient temperature, charge voltage and other parameters. Cycle use is to use the battery by repeated charging and discharging in turn.
What is multi stage charging of a lead acid battery?
In the multi stage charging of a lead acid battery, the charger goes into a bulk charging state where the current and voltage are at a higher rate to get a majority of the battery charged. The next stage of the charging process is also known as absorption charge.
How to control constant currents in a power supply?
Another method of controlling constant currents is by connecting the external circuitry to the power supply in addition to the method explained previously where the overcurrent protection function is diverted. The example below is using TDKs HWS1000 and will explain the process.
How do you maintain a charge on a lead-acid battery?
To maintain a charge on the cell, the charging voltage must be slightly higher than the OCV in order to overcome the inherent losses within the battery caused by chemical reaction and resistance. For a lead-acid battery, the value above the OCV is approximately 0.12 volts.
How a battery is charged at a constant voltage?
In this method the charging current is high in the beginning when a battery is in discharged condition, and it gradually drops off as the battery picks up charge resulting in increased back emf. Charging at constant voltage may be carried out only when the batteries have the same voltage, for example, 6 or 12 or 24 V.
