Battery Management System (BMS) TINY BMS v2.2

The Tiny BMS – v2.2 High Power battery management system is an essential element of any lithium battery. Enepaq Tiny BMS supports lithium batteries of any chemistry and up to 60 V nominal. It is easy to manage battery capacity from below 1 Ah to 655 Ah. Tiny BMS measures the individual voltages of parallel cell groups and manages the switching of the load and the charger. During charging, the cells are balanced by draining higher cells to achieve full balance and maintain the good condition of the battery pack. The state of charge is also calculated and is available via the communication bus for display to the user.

Advanced features:

• Dissipative balancing up to 150 mA
• Support for up to two external temperature sensors and one dual-range current sensor
• Event log and usage statistics for detailed analysis
• Free firmware updates to keep the BMS always up to date
• Programmable inputs and outputs for extended functionality

Compact design:

Ultra-compact dimensions (95 × 65 × 10.8 mm, only 114 g) ensure maximum space utilization efficiency in your application.

Current sensor connection:

Facilitates integration with external current sensors.
