The Cell Interface has been designed to meet the requirements of SAE J2464 (shock) and SAE J2380
(random vibration).
Standards and Certifications
The Cell Interface meets industry standards CISPR 22 Class A and IEC/EN 61000-4-2 for EMC/EMI
and ESD respectively. It has been designed to meet EN 60950 high voltage creepage/clearance
distances for reinforced insulation rated to 1250 V DC. All components are EU RoHS / China RoHS
compliant.
Standard/Certification
Stationary Battery Safety
UL Recognized
UL 1973 (file no. MH64071)
Functional Safety
UL Recognized
UL 991 (file no. MH64071)
UL 1998 (file no. MH64071)
UL 1973 recognition ensures safe battery operation and significantly reduce the effort of certifying the
energy storage solution to meet UL 1973 and UL 9540.
Maximum Stack Deployment
Cell Interface modules are deployed as a daisy chain to monitor the cells of a stack. The maximum
number of modules that are supported in a stack depend on two metrics:
▪
the maximum number of modules that can be powered over Link Bus power (if required)
▪
the required scan rate of the cell voltage measurements
