Detailed Charging Voltage Guidelines
For applications involving 36V battery systems, such as those found in solar energy setups or electric vehicles, the correct charging voltage becomes even more crucial. Here are the detailed guidelines:
Recommended Charging Voltage for 36V Systems
A 36V LiFePO4 battery pack typically comprises 12 cells in series, each with a nominal voltage of 3.2V. To ensure complete charging without overcharging, the total recommended charging voltage for the pack is 43.2V. This allows for a per-cell voltage of 3.65V, which is ideal for maintaining battery health and performance.
Allowable Voltage Range
To accommodate variations in charging conditions and battery tolerance, a slight range around the recommended voltage is permissible. For a 36V system, the allowable charging voltage range is 42.0V to 43.8V. Staying within this range ensures that the battery is fully charged without exceeding safe limits.
