Product Functions and Advantages

Fast uniform charge and discharge of batteries

Series battery packs are widely used in various fields as power sources, but the series structure results in the inability of each individual battery to automatically balance during charging. Excess energy can only be dissipated in the form of heat, thus damaging the heat-generating individual batteries. This greatly affects the performance and lifespan of the battery pack.

The ITS5300-003 battery uniform charge and discharge test system monitors the voltage of individual batteries in real time, and can independently charge and discharge individual batteries with unbalanced voltages in the group, thereby effectively improving the usable capacity of the battery pack and extending its lifespan. During the setting of each step, the voltage, current, and voltage difference of uniform charge and discharge can be set simultaneously. When the voltage difference between individual batteries meets the set value, the bipolar uniform charge and discharge power supply will perform independent charge and discharge operations on the individual batteries.

Modular Design Structure
 

The ITS5300 battery charge and discharge test system consists of an industrial computer, electronic load, power supply, internal resistance analyzer, and temperature acquisition instrument. It provides professional test steps to help users greatly improve testing efficiency. At the same time, with the help of system software, synchronous remote control of all devices in the system can be achieved. The modular design allows users to select instruments suitable for their own testing needs to build an automated testing platform, thus providing greater flexibility and scalability to the system architecture.

Power-off Memory Protection Function

Compared to the single protection setting of traditional integrated charge and discharge units, the ITS5300 battery charge and discharge test system features a power-off memory function.
The power-off memory function is specifically designed and developed for long-term aging tests. It effectively ensures that data collected during long-term aging tests, under conditions such as abnormal power failure or computer crashes, can still be perfectly preserved. After the system resumes normal operation, the program continues from where the error occurred, avoiding the trouble of repeated testing and improving testing efficiency.
Similarly, if the system remains powered off, it will automatically disconnect the charging or discharging circuit, preventing overcharging and over-discharging of the battery, and protecting the safety and reliability of the battery experiment.
 

Real-time Monitoring of Charge and Discharge Status of Each Channel

Battery packs are usually composed of series-connected individual batteries. During the charge and discharge process, the charge and discharge characteristics of individual batteries vary, therefore monitoring individual batteries is particularly important.

In addition to the important parameters of each channel, the ITS5300 system can achieve real-time monitoring of individual voltage, internal resistance, and temperature values by setting up a temperature meter and internal resistance meter.

During the test, users can also clearly observe the test information of each channel through the test software interface. Using colored block diagrams to warn whether the individual characteristics are normal or abnormal, intuitive and clear at a glance, improves test reliability. This includes channel configuration information, voltage, current, discharge capacity, and other parameters of the corresponding battery in each channel, facilitating observation and recording.
