JackB, the question at hand is hot "fires" but fires in LiFePO4 applications. The LincVolt web site makes no metion of LiFEPO4, and the NYTimes refers to that car having a "lithium-ion" battery
, which is usually not how the proud patent holders for LiFEPO4 refer to their products.
Whether the issue is the batteries or the charging
circuits, the question about lithium battery systems
in general, is whether there is a fire danger
. Building a charger
that has no inherent fire hazard is easy, it has been done millions of times. But then again, even wall warts and toaster ovens cause fires.
