Abstract:
A battery pack (200) includes a power limiting apparatus (230) comprising a power limiting resistor (232) in series with an overcurrent protection device (234). A switch (236) under the control of a data line (202) is placed in parallel with the series coupled power limiting resistor (232) and overcurrent protection device (234). When the switch (236) is enabled via the data line (202), current limiting is provided via the switch and a fuse. When the switch (236) is disabled via the data line (202) current limiting is provided via the overcurrent protection device (234) which limits the maximum battery system current.
