CONDITIONS OF ACCEPTABILITY

  1. The battery module including its battery management system has been tested according to the functional-safety requirements of ANSI/CAN/UL-1973:2022, Third Edition. Solid state circuits and software controls relied upon as the primary safety protection, have been evaluated by CSA Group to meet requirement of this standard. Any change to the software and electronic controls of the BMS required additional evaluation by CSA Group.

  2. The enclosure was evaluated only to establish Type rating of Type 3R with standard CSA C22.2 No. 94.2/UL 50E - Enclosures for Electrical Equipment, Environmental Considerations.

  3. Further evaluation for Salt Fog shall be required for the battery system intended to be used in the end product where salt fog condition were applied.

  4. Corrosion due to electrochemical action is to be determined for conductive parts in contact with terminals when subjecting to the installation of the end products.

  5. Equipment Application Location: Stationary

  6. Access Location: Operator Accessible.

  7. The installation was not evaluated. The battery system shall be installed in accordance with NFPA 70 or CSA C22.1 (Canadian Electric Code) or other applicable installation code.

  8. Overvoltage Category (OVC): III

  9. Pollution Degree(PD):3

  10. Altitude for Operation: Up to 3000 m.
