6. Setup and Installation

1. Connect the AC Power Cord: Insert the AC power cord into the charger unit's input port.
2. Plug into Power Outlet: Plug the other end of the AC power cord into a standard 110V AC wall outlet.
3. Connect to Scooter: Carefully insert the DC output connector (round plug) from the charger into the charging port of your electric scooter. Ensure the connection is firm and secure.
4. Observe Indicator Light: The LED indicator on the charger will illuminate to show the charging status.

7. Operating Instructions

The SAYSOLAK charger utilizes a smart 3-stage charging algorithm (Constant Current, Constant Voltage, and Trickle Charging) to optimize battery health and charging efficiency.

Image 6: A graph depicting the three stages of the charging process: Constant Current Mode (T1), Constant Voltage Mode (T2), and Trickle Floating Charging (T3), showing how current and voltage change over time to optimize battery charging.

• Constant Current (CC) Mode: The charger delivers a constant current to the battery until it reaches a certain voltage level. This is the fastest charging stage.
• Constant Voltage (CV) Mode: Once the battery reaches the target voltage, the charger maintains a constant voltage while the current gradually decreases.
• Trickle Charging: After the battery is nearly full, the charger switches to a low-current trickle charge to maintain full capacity and prevent overcharging, extending battery lifespan.

The charger features a fanless design and utilizes imported electronic components for excellent automatic heat dissipation, ensuring silent operation during charging.

The integrated smart copper chip helps reduce power loss and improve overall charging efficiency.

8. Charging Status Indicator

The built-in LED indicator light provides clear feedback on the charging status:

• Red Light: Indicates that the battery is currently charging.
• Green Light: Indicates that the battery is fully charged or the charger is disconnected from the scooter.

9. Maintenance and Care

• Cleaning: Wipe the charger with a dry, soft cloth. Do not use liquid cleaners or solvents.
• Storage: Store the charger in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• Cable Care: Avoid bending or crimping the power cords excessively. Do not place heavy objects on the cables.
• Durability: The charger's shell is made of high-quality ABS material, which is fireproof and flame retardant. It also utilizes wave soldering technology for stronger sealability and added corner reinforcement for better shockproof performance.

10. Troubleshooting

Problem: Green light remains on after unplugging the power supply.

Solution: This is normal behavior. The charger has built-in capacitors that store energy during charging. When the power supply is unplugged, the energy in the capacitors is not released immediately, causing the green light to remain on for a short period until the energy is fully exhausted.

Problem: Charger LED does not light up or remains green when connected to scooter.

Solution:

• Ensure the AC power cord is securely plugged into both the charger and the wall outlet.
• Verify the wall outlet is functioning correctly by testing it with another device.
• Check if the DC output connector is fully and correctly inserted into the scooter's charging port.
• Confirm that your scooter's battery is not already fully charged.
• Ensure your scooter model is listed as compatible and uses a 36V lithium battery with a 5.5*2.5mm or 5.5*2.1mm DC jack.

Problem: Charger gets excessively hot during use.

Solution: While some warmth is normal, excessive heat may indicate an issue.

• Ensure the charger is placed in a well-ventilated area, away from direct sunlight or heat sources.
• Do not cover the charger during operation.
• If overheating persists, discontinue use and contact customer support.
