Heltec BMS HT-10C Battery Equalizer User Manual

Inleiding

The Heltec BMS HT-10C Battery Equalizer is designed to maintain voltage balance between two series-connected 12V batteries, including Gel, Flood, and AGM Lead Acid types. This device ensures optimal battery performance and extends battery lifespan by preventing overcharge and over-discharge conditions between individual batteries in a series bank. It actively transfers energy from higher voltage batteries to lower voltage batteries, ensuring all batteries in the series remain at a balanced voltage vlak.

Beeld: Voorkant view of the HT-10C Battery Equalizer, displaying its screen with battery voltage readings and charge status. The screen shows "Bat.1 12.4V" and "Bat.2 00.0V" with a 36% charge indicator, along with "B03" and control buttons labeled "SET" and "DOWN".

Sleutel kenmerke

• Battery Energy Transfer: Functions as a practical and multi-functional battery equalizer, providing protection against battery overshoot and over-discharge.
• Voltage Balansering: Specifically designed for batteries connected in series to maintain equal voltage levels across them.
• Outomatiese werking: The equalizer activates when a voltage difference between two batteries exceeds a specified threshold (e.g., 50 millivolts), transferring current from the higher voltage battery na die onderste voltage battery.
• Duursame konstruksie: Features a robust shell designed for long-serving life.
• Wye toepassing: Compatible with various battery types including Lead-Acid, Gel, Flood, and AGM batteries.

Image: Diagram illustrating the working principle of the Heltec battery equalizer. It shows that the equalizer is an energy transfer device that compensates for voltage differences. When the voltage difference exceeds 50 millivolts, current flows from the higher voltage battery na die onderste voltage battery, automatically maintaining balance. It also depicts how sulfation can occur in unbalanced batteries ("Before") and how the equalizer helps maintain balance ("After") for series or parallel connections.

Spesifikasies

Note: Some specifications are derived from the product data and may represent system-level parameters rather than the equalizer's direct input/output for balancing.

Opstelling en installasie

The HT-10C Battery Equalizer is designed for easy integration into battery systems. Follow these steps for proper setup:

1. Identifiseer batteryterminale: Ensure you correctly identify the positive (+) and negative (-) terminals of each 12V battery in your series connection.
2. Connect Equalizer to Batteries:
   • Connect the equalizer's B1+ terminal to the positive terminal of the first battery (Bat.1).
   • Connect the equalizer's B1- terminal to the negative terminal of the first battery (Bat.1).
   • Connect the equalizer's B2+ terminal to the positive terminal of the second battery (Bat.2).
   • Connect the equalizer's B2- terminal to the negative terminal of the second battery (Bat.2).
3. Reeks verbinding: Ensure your two 12V batteries are connected in series to achieve a 24V system. The equalizer will balance these two batteries.
4. Multi-Module Connection (Optional): For systems with more than two batteries in series (e.g., 48V systems with four 12V batteries), multiple HT-10C equalizers can be connected in parallel to balance each pair of batteries. Refer to the connection diagrams for guidance.

Image: This image includes "Pic.1" demonstrating the balancing process where voltage is transferred from a higher voltage battery to a lower one until balanced. "Pic.2" shows the connection for two batteries (one equalizer) and "Pic.3" shows how to connect two equalizers for four batteries in series, illustrating multi-module parallel connection.

Bedryfsinstruksies

Once correctly installed, the HT-10C Battery Equalizer operates automatically. The LCD display provides real-time information about your battery system.

• Automatic Balancing: The equalizer continuously monitors the voltage of the connected batteries. When a voltage difference of 50mV or more is detected, it automatically initiates current transfer to balance the voltages.
• LCD-skerm: The integrated LCD screen shows the voltage of each connected battery (Bat.1 and Bat.2) and the overall charge percentage. This allows for quick visual inspection of battery health and balance status.
• Aanwyser-LED's:
  • Krag LED: Indicates that the equalizer is powered on and receiving voltage from the battery system.
  • Equalizer LED: Illuminates when the balancing process is active, indicating that current is being transferred between batteries.
• Control Buttons (SET/DOWN): These buttons are typically used for initial setup or to cycle through display modes, if applicable. Refer to the on-screen prompts for specific functions.

Onderhoud

The Heltec BMS HT-10C Battery Equalizer is designed for minimal maintenance. However, periodic checks can ensure its continued optimal performance:

• Visuele inspeksie: Periodically inspect the equalizer and its connections for any signs of damage, corrosion, or loose wiring. Ensure all terminals are securely fastened.
• Netheid: Keep the equalizer clean and free from dust, dirt, and moisture. Use a dry, soft cloth for cleaning. Do not use abrasive cleaners or solvents.
• Omgewingstoestande: Ensure the equalizer is operating within its specified temperature and humidity ranges to prevent damage.
• Battery gesondheid: While the equalizer helps maintain balance, it is important to regularly check the overall health of your batteries. An equalizer cannot fix a fundamentally faulty or degraded battery.
