The TDT-8253 is a Battery Management System (BMS) designed to provide reliable protection and control for lithium battery packs. It is optimized for 13-series (13S) lithium-ion battery packs with a nominal voltage of 48.1V and a maximum operating current of 20A. This BMS integrates advanced circuitry for ensuring battery safety, longevity, and performance.
Features:
- Common Port Design where combines charging and discharging through a single port, simplifying wiring and reducing space requirements.
- Overcharge Protection where prevents overcharging of individual cells to avoid battery damage or hazards.
- Over-discharge Protection where stops discharging when the battery voltage drops below safe levels, preventing deep discharge damage.
- Overcurrent Protection where automatically shuts off power during excessive current draw, safeguarding the battery and connected devices.
- Short Circuit Protection where protects the battery and load from damage due to accidental short circuits.
- Temperature Monitoring where ensures stable operation by monitoring battery temperature and triggering shutdown in extreme conditions.
- Balancing Function where balances individual cell voltages during charging to maintain battery health and extend the lifespan of the pack.
- Compact and Lightweight where designed for integration in space-constrained applications.
