How to Achieve "Fully Automatic Discharge and Charging" Of Battery Capacity? Why Can't the Battery Recovery Idle Time Be Saved?

The most painful part of conducting a 10 hour rate battery capacity discharge test at a substation is staying up late on duty: starting to discharge during the day, it often takes until midnight or even early morning to complete the discharge. Under traditional operation, the tester must stay on site late at night, shut down the discharge box, and then hastily connect the charger to restart it. A slight negligence that causes the battery to discharge excessively or remain idle for a long time may result in the battery being completely scrapped. The "discharge charging integrated cycle mode" of HZCF-400 has completely ended this torment.

One click start, automatic closed-loop

Select the "Discharge Charging" function in the main menu of the tester, and the operator can pre configure the discharge parameters (such as termination voltage, discharge capacity, and cell cut-off value) and charging parameters (equal recharge, float recharge, charging current) in one go. After starting the instrument, perform deep nuclear discharge first. Once the termination condition is triggered, smoothly cut off the discharge circuit immediately.

Key Details: Defined 'Battery Recovery Waiting Time'

After the discharge is completed, the device does not immediately switch to a high current charging state, but automatically enters the "discharge to charge waiting" countdown. The screen will clearly display: "00:30" represents the preset waiting time, "00:01" represents the recovered time, and "00:29" represents the remaining waiting time.

Many on-site personnel do not understand why they have to wait? Because at the end of the high current discharge of the battery, the surface of the electrode plate is in a severe concentration polarization state, the electrolyte density is extremely uneven, and the internal temperature of the battery is high. If a high current is immediately injected at this time, it is highly likely to cause uncontrolled heating or severe gas evolution. HZCF-400 supports customizable static recovery time from default 1 minute to a maximum of 99 hours and 59 minutes, allowing chemical reactions to fully retract and terminal voltage to steadily rise before automatically recharging the battery in a scientific three-stage mode, truly achieving safe and reliable unmanned operation throughout the entire process.
