Pokyny pro nastavení

Follow these steps to set up your UMLIFE charger board:

  1. Identifikujte body připojení: Locate the IN+, IN-, B+, B-, OUT+, and OUT- pads on the charger board.

    Obrázek: Shora dolů view of the charger board. This image clearly shows the input (IN+, IN-), battery (B+, B-), and output (OUT+, OUT-) connection points, which are crucial for proper wiring.

  2. Připojte baterii: Connect your 3.7V lithium battery to the B+ and B- pads. Ensure correct polarity: B+ to the positive terminal of the battery, and B- to the negative terminal.
  3. Připojení zátěže (volitelné): If you intend to power a device directly from the charger board while charging, connect your load to the OUT+ and OUT- pads. Note that the "Battery+" and "Output+" terminals are electrically bonded together. The "Output-" and "Battery-" terminals are electrically isolated.
  4. Připojte napájecí zdroj: Insert a USB Type-C cable into the board's Type-C port. Connect the other end of the cable to a 5V to 6V USB power source, such as a mobile phone charger or a compatible PD fast charging head.
  5. Activate Protection Board: For the first use, it is necessary to connect the power supply to activate the integrated protection board.

Návod k obsluze

Once connected, the charger board will begin charging the lithium battery. Observe the LED indicators for charge status:

  • Indikátor nabíjení: A red LED typically indicates that the battery is currently charging.
  • Charged Indicator: A green or blue LED typically indicates that the battery is fully charged.

Charging Cycle Behavior:

  • The charging cycle automatically terminates when the charging current drops to 100mA after reaching the final float voltage (4.2 V).
  • Pokud je baterie objtage drops below 4.05V (approximately 80% to 90% of capacity), the charging cycle will automatically restart.
  • For batteries with voltage below 2.9V, the board initiates a pre-charge phase with a current of 100mA.

Ochranné vlastnosti:

The board includes an integrated protection circuit to safeguard the battery and the module:

  • Voltage ochrana: Zabraňuje nabití baterie nad bezpečnou úroveňtage limit.
  • Ochrana proti nadměrnému vybití: Prevents the battery from discharging below 2.4V, extending battery life.
  • Ochrana proti nadproudu: Limits the output current to 4A to prevent damage from excessive load.

Údržba

To ensure the longevity and proper functioning of your charger board:

  • Udržujte desku čistou a bez prachu a nečistot.
  • Nevystavujte desku vlhkosti nebo extrémním teplotám.
  • Ujistěte se, že všechna připojení jsou bezpečná a řádně izolovaná, aby se zabránilo zkratu.
  • Nepřekračujte stanovený vstupní objemtage range (5V-6V) or output current (1A charging, 4A protection limit).

Odstraňování problémů

ProblémMožná příčinaŘešení
Baterie se nenabíjí / Žádná LED indikace
  • Nesprávný napájecí zdroj objtage.
  • Loose or incorrect battery connection.
  • Protection board not activated (first use).
  • Faulty Type-C cable or power source.
  • Zajistěte vstupní objtage je 5V-6V.
  • Verify battery polarity and secure connections.
  • Connect power supply to activate the board.
  • Zkuste jiný kabel typu C a napájecí adaptér.
Board gets excessively hot
  • High charging current or excessive load.
  • Špatný odvod tepla.
  • Short circuit in battery or load.
  • Ensure charging current does not exceed 1A. Reduce load if connected.
  • Provide adequate ventilation around the board.
  • Zkontrolujte, zda nedošlo ke zkratům v kabeláži.
Battery not reaching full charge
  • Degradace baterie.
  • Charging current too low.
  • Test the battery with another charger or replace it.
  • Ensure the power supply can deliver sufficient current (at least 1A).
