Analysis
of battery cable faults using a dynamic battery model.
Paper
Nosh K. Medora, Managing Engineer, Electrical and Semiconductors
Practice, Exponent Failure Analysis Associates
Alexander Kusko
Batteries at a low state of charge not only have a lower terminal
voltage, but also have an internal resistance up to three times
the nominal value. Heating of the cables during a fault also increases
the circuit resistance. The consequence can be a low fault current,
with a time delay, or a failure of the fuses to trip, possibly resulting
in a fire. This technical paper uses a battery model to generate
the appropriate terminal voltage and fault current as a function
of the state of charge for different cable power density configurations.

Rate
adjusted battery capacity testing and calculations.
Paper
Steve Clark, Battery and DC System Engineer, South Texas Project
Nuclear Operating Company
This paper does not address all aspects of capacity testing. Rather,
it reviews the less commonly used method of capacity testing known
as “rate adjusted testing.” It then looks at how the
principles of rate adjusted testing can be applied if things go
wrong during a traditional time adjusted capacity test. This includes
real world examples to demonstrate how to calculate battery capacity
using Peukert’s Law and linear interpolation. These examples
illustrate how we can effectively calculate capacity for a time
adjusted test, even if the test is halted early because of equipment
problems or human error.

to fade. Unfortunately, by the time they start developing their
back-up power strategy, batteries at the premises may be failing.
To avoid power-related trouble early on, carriers must map out a
strategy sooner rather than later. This paper discusses that strategy:
quality of service, customer satisfaction, recycling programs, and
product liability as it pertains to replacement batteries.
