Regulation 5.8.3 |
| Question: |
|
For over-current protection with li-ion batteries, is a standard DC fast blow fuse sufficient? also, the regulations don't go into much detail, but the BPS testing precedure document implies that a relay will be used for the BPS. is MOSFET switching acceptable for the battery protection system?
|
| Official Response: |
|
Fast blow fuses are not acceptable for BPS overcurrent protection as their performance is too variable. MOSFETs are not acceptable for BPS shutoff as they can fail shorted.
