CC Chg: The channel is charged with a constant current value, and the battery voltage is raised. The cut-off voltage and the constant current value must be set. Time, capacity, energy are the conditions of choice, it means “or” logically relations among them. The figure above indicates that the battery charges from the beginning of 1200mA current to the end of the 4.2V.

CC DChg: The channel discharges at constant current, and the battery voltage drops, in which the cut-off voltage and the constant current value must be set. Time, capacity, energy are alternative conditions . It means “or” logically relations among them. The figure above indicates that the battery discharges from the beginning of 1200mA current to the end of the 2.8V.

Rest: The channel is rest. The step time must be set. The picture above indicates that the channel will rest for 5 minut.

Explanation of Common Steps with Neware Battery Cycle Tester

Cycle: Define multiple steps for cycling . The figure above indicates that step 1 or step 2 will be performed 5 times from the first step.

CCCV Chg: When the battery voltage is below the set voltage value, the device charges the battery in a constant current mode until the battery reaches the set constant voltage value and then enters a CV process. The figure above shows that the battery is charged by 1200mA, and the battery enters the CV process at 4.2V, where the voltage remains constant and the current drops slowly until the current goes down to 50mA. Lithium battery charging and CV-Chg to CC-Chg process, the step voltage, current, off current.

CP DChg: The channel is equivalent to a battery with a constant power load, and the current in the discharge increases with the decrease of the voltage. The product of current and voltage at Neware BTS 8.0 user manual 16 any time is equal to the set power value. As shown above, the battery discharges at constant power of 10W until the end of the 2.8V (assuming that the battery voltage is 5V, the discharge current = 2A, and when the voltage drops to 4V, the current should be 2.5A). The cut-off voltage and power value must be set.

CV DChg: Adopt it when the voltage required to be constant during the discharge, and the discharge current will gradually decrease. As shown above, the battery discharges at the maximum 2000mA (if less than 2000mA, discharges at the actual value, which depends on the battery voltage) until the voltage reaches 3.0V, then the voltage remains constant and the current begins to decrease, and the step will finish when the current falls to 200mA. If the current value is not set in this step, the starting Neware BTS 8.0 user manual 17 current discharge value may reach the full scale current (depending on the initial voltage). This step requires hardware support.

CCCV DChg: Discharge at a constant current value, when the voltage drops to the setting voltage, the voltage remains constant, the current gradually decreases, and then the step comes to the end when it drops to the cut-off current. As shown above, the battery discharges at 1200mA and decreases when voltage reaches by 3.5V, then the step finishes when

IF: The insertion of this step in any step is supported, and judge the direction of the step goto by its parameters. As shown below, you can add voltage, step time, environment temp and current, then you can choose Goto to the target step.
