Battery Repair System Product Description And Overview

In the system, a large-scale battery professional comprehensive treatment equipment integrating charging, detection, battery repair system, and activation can process 22 batteries at the same time, with a maximum processing capacity of 220AH batteries, which is especially suitable for the detection, maintenance, and repair of lead-acid batteries in various electric vehicles, and the use of extended batteries. Life expectancy has obvious effects.

Performance Characteristics-

  1. The equipment adopts an independent modular structure design, which is easy to maintain, and each module does not affect the other. Even if individual modules fail, it will not affect the normal use of other modules.
  2. The circuit is connected by a plug-in, which is convenient for replacement.
  3. There will be no overcurrent or overvoltage at work.
  4. It has polarity protection, anti-reverse connection, and other functions.
  5. Built-in fan to help heat dissipate heat and improve stability.
  6. Pulse repair: High-frequency pulse desulfurization technology is adopted, which has a good non-destructive repair effect on sulfated batteries. The current is adjustable during work to accommodate different specifications of batteries.
  7. Activation repair: The battery is specially strengthened with a pulsed high current (peaking up to 200A), which has a significant effect on activating severely vulcanized batteries (which cannot be charged or discharged).

Special Tip: Taking advantage of the large activated output pulse current, batteries with a capacity greater than 24AH can be charged and pulsed repaired.

Layer 3: Second-way high-frequency activation

The sixth activation is a single-way output. Through high voltage and low current, the activation and activation of the battery (no charge and no discharge) is completed to achieve the purpose of repairing the battery.

The Operation Process is as follows:

1. Screw the current knob to the minimum,
2. Press the reset button,
3. Turn on the activation power switch. The red indicator light in the switch is on.
4. Clamp the battery (red clip to the positive electrode of the battery, and the black clip to the negative electrode of the power supply). The range of the voltmeter is 18V and 50V. At this time, the ammeter shows that the current is 0, and the voltmeter shows the current battery voltage.
5. Pick up the reset button

6. Adjust the “Activation Current Adjustment Knob”, and the ammeter is displayed as the current size of the battery processing. The current adjustment range is 0~10A (clockwise twist knob, increased current; reverse clockwise twist knob, reduced current)

Special Tips:
1. When the output line is short-circuited or the battery polarity is reversed, the instrument will be automatically protected within 2 seconds, and the output current is zero. At this time, the red “replace” button should be pressed after troubleshooting. At this time, the instrument protection is unlocked and normal.
2. Turn on the power switch without connecting the battery, the voltmeter shows that the voltage is activated output voltage. The voltmeter pointer will hit the head.

3. Because the whole machine consumes large power, the power supply line section requires >-2.5 square millimeters.
