Description

Battery Management System (BMS) 150A/750A

Battery Management System (BMS) 30A the Tiny BMS is an essential component of every Lithium battery. Enepaq Tiny BMS supports lithium batteries of any chemistry and up to 60 V nominal. Battery capacity from sub-1 Ah to 655 Ah can be managed easily. Tiny BMS measures individual voltages of parallel cell groups and manages switching of load and charger. During charging, cells are balanced by bleeding-off higher cells to accomplish full balance and maintain good health of battery pack. State-of-Charge is calculated as well, and is available via communication bus to be displayed for user.

FLEXIBILITY

User-upgradeable firmware allows quick updates, bringing bugfixes, new features and other improvements, such as client-specific functionality. Integrated communication bus allows easy reconfiguration and streaming of real time data, while extension I/Os enables operation with various external peripherals: current sensors, contactors, Enable switches, SOC gauges and more.

SAFETY

To ensure the security of you and your surroundings, please read these rules and follow all the guidelines contained installation instructions of our Battery Management System (Tiny BMS):

• DO NOT use the system where it may cause interference (eg. medical equipment);
• DO NOT use the system in an explosive environment;
• The system is NOT resistant to the chemical environment and mechanical stress;
• All electrical equipment MUST be rated for the voltage of the battery and battery management system;
• Use double-insulated tools;
• DO NOT short-circuit the battery or battery management system terminals, this could cause the damage to the product or the personal property;
• DO NOT lay tools or metal parts on top of the batteries or near the battery management system cable lugs;
• Before establishing connections, make sure to verify polarity.

This list is not exhaustive, and it is the responsibility of the system designer / installer to conduct their own failure mode analysis and determine what is required.

Working around batteries is DANGEROUS. Risk associated with improper use of the battery with the Tiny BMS device includes: short-circuit, fire or explosion.

Read the ENTIRE documentation to become familiar with the Tiny BMS device and its features before operating. Failure to operate the product correctly and safely may result in damage to the product, personal property and cause serious injury.

Throughout the literature the term “Note:” will be used to indicate procedures which, if not properly followed, create a possibility of physical property damage.

Using Tiny BMS device requires at least basic knowledge in electronics and electrical engineering. Enepaq will not be held responsible for damage to the battery or any consequence, if the Tiny BMS device is used improperly and no warranty is provided in such case.
