Battery Charge/Discharge Devices and Systems (YRD Series) |
|
Today, we use a range of both big and small batteries, from lithium-ion batteries in cell phones and notebook computers, to the batteries used in hybrid cars. In the development of battery-powered devices, obtaining basic data such as battery durability is essential for verifying the reliability of products. It used to be the case that in order to build such a system, it was necessary to provide a battery charge/recharge device (since there were no high-capacity products available, the power supply and load had to be furnished separately), a data logger, and accompanying software for controlling this equipment. From a time and cost perspective, this was impractical. In response to this, YAMABISHI developed a new battery charge/discharge device designed specifically for charging and discharging equipped with a dedicated data logger and software. This product is ideal for reducing the time required for developing battery-powered products. |

 |
High precision and high speed
Uses a dropper system for high-precision, high-speed load changing. Also maintains low voltage and current ripples. |
|
|
Low Noise. Low Ripple.
Switching is unnecessary, so no emission noise is generated. |
|
|
Interface (Ethernet/CAN)
An Ethernet communication interface has been implemented, and can be automatically operated from an external PC. By mounting a CAN (Control Area Network) interface, the auto industry standard, internal data can be collected and logged in blocks from the battery controlling the CAN interface. |
|
|
Local operation (touch panel/jog dial)
Mounted with Yamabishi’s common touch panel and job dial for charge/discharge devices. Using these, low-capacity bench use charge/discharge tests can be performed without a PC. Moreover, screens can be added for controls that are required as part of user test systems using the customization options (such as conductor ON/OFF). |

|
Compact, highly efficient
By implementing an inverter system, we were able to achieve a charge/discharge device that is not only compact, but also highly efficient (with a charge time of 85%). The regeneration of electrical power during loading creates an environmentally friendly system that uses energy efficiently. |
|
|
A diverse range of control modes
The charge/discharge device supports constant current charge/discharge, constant voltage charge/discharge, constant power charge/discharge, constant resistance, discharge and pulse modes.
|
| |
|
High-speed responsiveness
Using an optimized control circuit, we achieved high-speed responsiveness for our regenerative inverter system (10 msec charge/discharge; 10 msec transient response). (Even higher-speed responsiveness is possible.) |

Simple operation
Dedicated software for performing battery characteristic tests. Even without any knowledge of programming, users can get started with just a few settings. |
| |
|
Scheduled operation
Can be operated automatically using pre-programmed schedules and triggers. |
| |
|
Multi-channel operation
Data logging for multiple charge and discharge devices connected via Ethernet can be controlled individually.
Different schedules can be run on individual charge/discharge devices, and the same schedule can be run on multiple devices, such as for production equipment.
Charge/discharge devices of different capacities and different types can be combined, and additional channels can be set up easily. |
Software specifications |
| |
|
Manual charge/discharge control
You can select from the following operation modes:
Constant current charge/discharge
Constant power charge/discharge
Constant voltage charge/discharge
Controls output (on/off).
Warning indications
Displays warnings, including warnings for excess voltage, current surges, excess power, and excess heat.
Schedule operation controls
Control of schedule operations, including start, stop, and discontinuation, and displays elapsed time.
Reading and saving charge/discharge files
Saves channel allocation and schedule/trigger programs to a disc.

Logical channel settings
Unit no., module no. and channel no. combinations are labeled (logical channel name) and entered. Management of channels is simple using trigger settings.
Module settings
Sets the module inserted in the data logger.
Unit settings
Sets IP address of the unit when collecting data simultaneously from multiple data loggers. |
 |
| |
|
|
|
| |
|
Schedule settings
Performs charging and discharging following pre-set programs (steps). In addition to charge/discharge directions, control directions, such as jump and loop, may be used. Data for scheduled operations is saved as a log file.
Trigger settings
If logical channel values specified during scheduled charging and recharging deviate from the tolerance values, defined operations (next step/suspension of operation) are run. In addition to instantaneous values, variations within a specified period of time can also be selected. For example, you can control the way the device switches over to discharge to prevent a rise in temperature during full charges. |

Data view
Logical channels can be monitored as numerical values. When viewing wave patterns in the Web view, wave pattern color and line width can be specified. |
 |
| |
|
|
|
| |
|
Wave view
Logical channel values are displayed as oscilloscope-like wave patterns. Wave color and line width can be specified for the data view. Time lines can be selected from 10/20/30/60 seconds. Also equipped with a function that displays detailed wave data when specific screen areas are selected. |

Highly expandable
Up to 8 modules, which can accommodate 24 channels each, can be stored in the data logger. Moreover, by linking multiple data loggers using a LAN cable, you can measure the voltage and temperature for up to 1,536 channels.
High-speed sampling
With an AD converter built into the module, the impact on sampling time due to an increase in the number of channels is minimized. The minimum sampling time of 100 ms does not change even if the number of channels is increased.
●Long-life
A semiconductor (high-compression PhotoMOS relay) is used for the multiplexer, so there is no need to worry about the duration of contact as with other logger products that use relay. In addition, DC 200 V is supplied between channels to eliminate channel-to-channel compression problems associated with other semiconductor multiplexer loggers, allowing the cell voltage of batteries connected serially to be measured without any problems. |
