Functions

Three charge modes

Constant current/constant voltage (CC/CV) charge

Constant current/constant voltage (CC/CV) charge

By setting both of current value and voltage value, the output exceeding the value you set can be disabled.

Constant current (CC) charge

Constant current (CC) charge

The charge is carried out at the current value you set. Even if the terminal voltage changes during charge, constant current can be passed.

Constant voltage (CV) charge

Constant voltage (CV) charge

The charge is carried out at the voltage value you set. Even if the charge current changes, 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 battery reaches the setting value, the charge is completed (only at constant current charge).
Setting of current
Set the current to complete the charge. If the current that is passed to battery reaches the setting value, the charge is completed (only at constant voltage charge).
Setting of -△V
For some batteries, the voltage increases when the charge is completed, and then the voltage decreases to complete the charge. The voltage reduction value at that time is measured and the charge is completed if the voltage decreases by -△V you set.

Three discharge modes

Constant current (CC) discharge

Constant current (CC) discharge

The discharge is carried out at the current value you set. Even if the terminal voltage changes during discharge, constant current can be passed.

Constant power (CP) discharge

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.

Constant resistance (CR) discharge

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.

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 battery reaches the setting value, the charge is completed.

Remote sensing

Remote sensing

The voltage reduction (VO-VL) due to resistance (R) of output line and degradation of stability due to contact resistance are prevented (up to 0.5 V).

Various protection functions

For charge-discharge test, various protection functions are prepared for protecting your devices and this unit.

  • OVP (overvoltage protection)
  • OCP (overcurrent protection)
  • UVP (under voltage protection)
  • OPP (over power protection)
  • OTP (internal over temperature protection 1)
  • OHP (internal over temperature protection 2)
  • OBP (external temperature protection)
  • ACF (input voltage reduction)
  • RS (remote sense line reverse connection protection)

Battery temperature detection 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

Software for remote control "CD-BC" (Standard equipment) *

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 charge-discharge test for various rechargeable batteries such as lithium-ion battery. It enables setting of test conditions, execution of test, confirmation of test status, and display and save of test result.

* Standard equipment is only controlling one channel version. If you want to control multiple channels, you need to purchase the CD-BC-512ch.

Features

  • The charge-discharge test (creating test condition to executing to checking) can be executed by dedicated software only.
  • Executing the charge-discharge test by using the charge-discharge power supplies made our company of maximum 512 units.
  • Checking the datalog during the test.
  • Executing the charge-discharge test linked with Espec's thermostatic 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 of test condition

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 selection of charge and discharge mode and setting of each protection function.

Creation of test condition display
2. Executing of test

Execute the test for each group you set.

On the execution screen, necessary information such as sequence, thermostatic chamber, 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.

Execution of test display
3. Checking of measurement data

Check the completed test data. You can check the data for each cycle of sequence. You can check status for each unit time and end condition of each cycle.

The data can be displayed as a graph.
