single wire connection with a ¼” quick connect terminal . The output is a “current sinking”
type circuit (see diagram below) that can handle 100mA (connects the discrete output to
battery ground if a fault is present). This output can be connected to an external 12V LED
or general-purpose discrete input of an EFIS. The fault output has three states: fast flashing
(2 second on/ 2 second off), slow flashing (5 second on/ 5 second off) or solid.
Operating Instruction
Normal Operation
Under normal operating conditions the battery performs as any lead acid battery, storing
energy from the charging system and supplying it when the charging system is off.
Abnormal Operation
Under abnormal conditions that exceed the operating limits of the battery the battery may
stop supplying power. Two such important examples are over-discharge and over-
temperature. The over discharge protection shuts off outgoing power when the battery is
95% discharged (supplied 95% of its available energy). The over-temperature protection
shuts off outgoing power when cells and electronics get too hot as the result of excessive
cranking (i.e. cranking the engine for more than 15 seconds within a 1-minute period).
Monitoring
The slow flashing fault can indicate an improper state of charge or a problem with the cells
internal to the battery. If the battery voltage is outside the normal range of operation, 12.8V
to 14.6V, the battery is over-discharged or over-charged, most likely the result of an issue
with the electrical/charging system. If the battery voltage is within the normal operating
range, with a slow flashing fault, it is indicating an abnormal condition with a cell, such as
one cell ’ s state of charge is very different as compared to the other cells (high cell charge
level imbalance). The slow flashing fault may come on briefly during or following periods
of high current charging, and is not a concern. But if the fault persist, comes on
consistently during changing, or remains (charging or not), the battery will need to be
replaced.
The solid fault indicates a BMS hardware failure. For example, if the micro-controller fails
the fault indication output is activated (on solid). If the fault persist, comes on and stays on,
the battery will need to be replaced.
The fast flashing fault is an indication of high temperature; temperature exceeding the
normal operating or storage limits of the battery.
The table below shows the most common fault conditions and possible causes.
Note: the
same table applies to our 24volt batteries, just double the voltage specified.
