3. Setup Instructions
3.1. Connecting the Battery Pack
- Connect Main Battery Terminals: Solder and connect the equalization cable on the total positive and negative electrodes of the battery pack. The total positive is typically blue, and the total negative is black.
- Connect Individual Cell Wires: Use the provided cable clamps to clamp the corresponding batteries in sequence. Ensure each terminal wire is connected to a clamp at the end, with a wire sequence number marked on it.
- Insulate Excess Clamps: Insulate any excess cable clamps that are not used.
3.2. Wire Sequence Test
After connecting the battery pack cables, they need to be tested using the wire sequence detection board to confirm correct wiring and prevent damage to the equalizer.
- Connect the battery pack cable to the wire sequence detection board.
- Each wire sequence corresponds to a light on the board. When the light is on, it indicates that the wire sequence is correct.
- If any light does not illuminate, it indicates a wiring error. Use a multimeter to measure the voltage between the corresponding string and adjacent strings to identify and correct the incorrect wire sequence.

3.3. Connecting to the Equalizer
After confirming the wire sequence is correct, connect the battery pack cable input ports and the battery total positive/negative input terminals to the D1524/D1024 equalizer in sequence. Each input port of the battery pack is clearly labeled with a numbered prompt.

4. Operating Instructions
4.1. Initial Setup on Device
- After powering on, touch the display screen to confirm the user guide and press the START button.
- Navigate to the 'Parameters Set' page. Enabling equalization involves three simple steps:
- Select the type of battery pack (Li-ion, LiFePO4, or LTO).
- Set the number of connected battery pack strings.
- Set the equalized start control voltage. Monitor the voltage of a single string battery of the battery pack, and if it is lower than this value, it indicates that the wire sequence is correct.
- Press 'Enter' to save settings.

4.2. Equalization Modes
The D1524/D1024 supports both charge and discharge equalization modes.
4.2.1. Discharge Equalization Mode
In this mode, the equalizer discharges individual battery strings that have a voltage higher than the set value until all strings reach a consistent voltage. This helps balance the battery pack by reducing the voltage of higher cells.
Figure 4.2: Discharge Balance Mode
4.2.2. Charge Equalization Mode
When charging, the equalizer ensures that all battery strings are charged to a unified voltage value. Strings above the set voltage will be discharged, while others will continue charging, preventing overcharge.
Figure 4.3: Charge Balance Mode
4.2.3. Integrated Operations (Charge and Discharge)
Pressing the START button simultaneously with CHG ON will initiate both discharge equalization and charging, achieving integrated operations for comprehensive balancing.
4.3. Monitoring and Control
- Main Parameters Page: Displays the battery pack's state of charge (SOC), total voltage, current, and power.
- Status Display Page: Provides real-time voltage changes for each of the 24 series batteries, total voltage, charging current, charging power, and temperature changes.
- Control Buttons: Use the 'STOP' button to pause discharge equalization, 'CHG ON' to start charging, and 'CHG OFF' to pause charging.
4.4. Bluetooth APP Control
The device supports mobile Bluetooth APP monitoring and long-range control. Connect your mobile phone via Bluetooth to the equalizer and use the dedicated applet to control and monitor the machine remotely.

4.5. Language Switching
The D1524 series equalizer supports both Chinese and English interface switching. To switch to English, press the equalization pressure difference setting button, enter the code '28972123', and select English from the menu.
5. Maintenance
- Ventilation: Always operate the equalizer in a well-ventilated environment due to the heat generated during energy consumption balancing.
- Obstruction: Strictly prohibit inserting foreign objects or metal objects into the heat dissipation area behind the equalizer case to prevent explosion.
- Environmental Conditions: Avoid balancing in humid, salt-fog, or high-temperature environments.
- Moisture: The interior of the equalizer is composed of precision electrical components. Strictly prohibit the instrument from entering water or mist, as it may cause damage.
- Power Sockets: Ensure the equipment is used with properly grounded power sockets.
- Connection Cables: Use only the battery pack connection line that is randomly matched with the equalizer. Do not add or modify the connection line, as this may lead to accidents.
6. Troubleshooting
6.1. Wiring Errors
If the wire sequence detection board lights do not illuminate correctly, it indicates a wiring error. Use a multimeter to measure the voltage between the corresponding string and adjacent strings to identify the incorrect wire sequence and adjust it before connecting to the equalizer.
6.2. Damaged Battery Packs
The equalizer cannot effectively balance or repair damaged battery packs. This includes, but is not limited to, packs with:
- Increased battery internal resistance.
- Voltage at the battery end lower than the discharge termination voltage.
- Short circuit or open circuit inside the battery.
- Damaged battery module BMS (protective board).
6.3. Protection Features
The device is equipped with various protection mechanisms:
- Total Voltage Overvoltage/Undervoltage: Enters protection state, forcibly shutting down charging/discharging MOS.
- Single Cell Overvoltage/Undervoltage: Enters protection state, forcibly shutting down charging/discharging MOS.
- Overcurrent Protection: Enters protection state when charging/discharging current exceeds limits, forcibly shutting down MOS.
- Over/Low Temperature Protection: Enters protection state when internal temperature is too high/low, forcibly shutting down MOS.
