Using a DC Regulated Power Supply to Perform Constant Current Discharge Testing The standard procedure for performing discharge testing on batteries is to use an electronic load. However, when performing constant-current discharge at high current levels, your electronic load needs to have a commensurately high input rating. If, for example,
This is partially because discharge rate becomes a greater issue as load current increases. At 250 mA, most lithium cells will be completely drained at even 3.6 volts. In order to make sure that you can actually use a LDO to do this, you will need to know your load current and the discharge curve of your battery.

But if the load is a constant current load (like a battery discharge testing machine) then the load current, naturally, stays constant. If the load is a constant power load, like a switching power converter itself loaded with a resistive load, then the output current could actually increase as the battery is discharged.
When discharging a battery, the SMU instrument operates as a sink, dissipating rather than sourcing power. Its voltage source is set to a level lower than the battery voltage. The current limit sets the discharge rate. When

There are two modes of battery charging and discharging: constant current mode and constant voltage mode. In a typical battery charging system, the batteries are charged or discharged at a constant current until the preset voltage is reached. After reaching the preset voltage, the system switches to the constant voltage mode.
To charge a battery using an SMU instrument, set the voltage source to the battery's voltage rating and the current limit of the source to the desired charging current. At the start of the charging cycle, since the battery voltage is less than the SMU instrument's voltage output, current will flow into the battery.
When discharging a battery, the Source Measuring Unit (SMU) sinks current because it is dissipating power rather than sourcing it. To draw current from a battery, the voltage source of the SMU instrument should be set to a lower level than the battery voltage and the SMU's current limit should be set to the desired discharge rate.
A typical battery discharge/charge test configuration includes a programmable power supply, an electronic load, an electronic switch, a voltmeter, and an ammeter. Synchronizing all these instruments into a working test station requires significant configuration time.
Therefore, battery formation and test systems require high precision analog front ends and controllers. There are two modes of battery charging and discharging: constant current mode and constant voltage mode. In a typical battery charging system, the batteries are charged or discharged at a constant current until the preset voltage is reached.
The use of rechargeable batteries in testing systems is becoming increasingly extensive. In order to initialize the rechargeable batteries, the multiple charging and discharging cycles are demanded. In this process, the current and voltage of the battery must be controlled accurately. It is usually required that the precision can reach 0.1%.
