A new classification of various DC fault interruption concepts, including simple mechanical means, solid-state circuit breaker (SSCB), hybrid circuit breaker (HCB), converter-based breakerless protection, and fault current limiter …
A battery protection unit (BPU) prevents possible damages to the battery cells and the failure of the battery. Such critical conditions include: Over-charge: is when the battery is charged over the allowed maximum capacity. High & low temperature: is when the internal temperature of the battery cells exceeds their safe operational temperature ...
Scope: This recommended practice provides guidance for the design of stationary dc power systems. The components of the stationary dc power system addressed by this recommended practice include the following: - Storage batteries - Static battery chargers/rectifiers (including sizing) - Distribution equipment - Protection equipment - …
Use MOSFETs with low Vt because the battery protection IC may only have 2–3 V to drive the gate. Conclusions.

It is important to understand the fault characteristics in DC microgrid in order to design an appropriate protection scheme. The most common faults in DC microgrid are pole-to-pole (PP) fault and pole-to-ground (PG) fault [40], [41].The first one has very low fault resistance since two poles of the DC bus are directly short-circuited, whereas the latter …
