Functions
Three Charge Modes
Constant Current/Constant Voltage (CC/CV) charge
By setting both the current value and voltage value, the output exceeding the value you set can be disabled.
Constant Current (CC) charge
The charge is carried out at the current value you set. Even if the terminal voltage changes during charge, a constant current can be passed.
Constant Voltage (CV) charge
The charge is carried out at the voltage value you set. Even if the charge current changes, a constant voltage can be applied.
Charge completion condition setting
- Setting of time
- The time can be set up to 999 hours 59 minutes 59 seconds by one-second unit. If the time reaches the setting time, the charge is completed.
- Setting of voltage
- Set the voltage value to complete the charge. If the terminal voltage of the battery reaches the setting value, the charge is completed (only at a constant current charge).
- Setting of current
- Set the current to complete the charge. If the current that is passed to the battery reaches the setting value, the charge is completed (only at a constant voltage charge).
- Setting of -△V
- For nickel-metal hydride (Ni-MH) and nickel-cadmium (Ni-Cd) batteries, the voltage rises when charging is complete, and then the voltage drops to complete charging. The voltage drop at that time is measured, and if the voltage drops by the set -△V, the charge is complete.
Three Discharge Modes
Constant Current (CC) Discharge
The discharge is carried out at the current value you set. Even if the terminal voltage changes during discharge, a constant current can be passed.
Constant Resistance (CR) discharge
The discharge is carried out at the resistance value you set. The value of terminal voltage is measured and the current value for discharge is decided according to the setting value.
Constant Power (CP) Discharge
The discharge is carried out at the power value you set. If the terminal voltage changes during discharge, constant power can be consumed according to the change.
Discharge completion condition setting
- Setting of time
- The time can be set up to 999 hours 59 minutes 59 seconds by one-second unit. If the time reaches the setting time, the charge is completed.
- Setting of voltage
- Set the voltage value to complete the charge. If the terminal voltage of the battery reaches the setting value, the charge is completed.

Remote function
External output ON/OFF
* As +S is set to common, input the external control voltage based on +S. Otherwise, a failure may be caused.
Remote sensing
The voltage reduction (VO-VL) due to resistance (R) of the output line and degradation of stability due to contact resistance are prevented (up to 0.5 V).
Various protection functions
For the charge-discharge tests, various protection functions are prepared for protecting your devices and this unit.
- OVP [overvoltage protection]
- OCP [overcurrent protection]
- UVP [under (low) voltage protection]
- OPP [over-power protection]
- OTP [internal over temperature protection 1]
- OHP [internal over temperature protection 2]
- OBP [over battery temperature protection]
- ACF [input voltage reduction]
- RS [remote sense reverse connection protection]
Battery Temperature Measurement Function
The temperature of a battery is measured by the temperature sensor. If the temperature becomes abnormal, charge and discharge are stopped in an urgent manner to protect the battery.

Software
Battery Cycle Test Software "CD-BC-1ch" (Attached) *
CD-BC is dedicated software for remote-controlling our company's charge-discharge power supply. It realizes ideal power supply control when you carry out the charge-discharge test for various rechargeable batteries, such as lithium-ion batteries. It enables the setting of test conditions, test execution, and confirmation of test status, as well as displays and saves test results.
* "CD-BC" is only controlling one channel version. If you want to control multiple channels, you need to purchase the CD-BC-Mch.
Features
- The charge-discharge test (creating test conditions to execute and check) can be executed by dedicated software only.
- Up to 256 units of the CD series can be used for battery cycle tests.
- Checking the datalog during the test.
- Executing the charge-discharge test linked with Espec's temperature chamber.
- Charge-discharge test for various batteries: lead-acid, nickel-cadmium (NiCd), nickel-metal hydride (NiMH), lithium-ion (Li-ion), and lithium-ion polymer (Li-ion polymer) are supported.
1. Creating test conditions
Create a condition for charge and discharge.
Up to 16 patterns of charge and discharge sequence can be set. You can set various test conditions according to purpose, such as selecting the charge and discharge mode and setting each protection function.
2. Executing tests
Execute the test for each group you set.
On the execution screen, necessary information such as sequence, thermostatic chamber, the status of power supply, voltage value, and current value at test can be monitored on one screen. If the test is executed for multiple groups at the same time, the statuses can be collectively monitored.
3. Checking measurement data
Check the completed test data. You can check the data for each cycle of the sequence. You can check the status for each unit time and end condition of each cycle.
The data can be displayed as a graph.
