Additional components required to assemble a BACS:
BACS Battery C-Module
The control of the charging and discharging processes of each accumulator during the
EQUALIZATION procedure as well as the measurement of the actual battery state are
carried out by so-called BACS® battery C-modules. These modules are mounted on each
individual accumulator. The according C module to be used in your battery system depends
on the battery used and must be dimensioned accordingly.
The key figures of the available C modules are documented in the current BACS data
sheets
BACS measuring cable
This cable is used to measure the voltage and impedance of the connected battery.
It is a 4-pin cable with 2 fuses in the positive cable (red) to protect the BACS
system against high currents or short circuits. When installing, the connection order
is important:This cable must be firmly connected to the battery poles BEFORE
connecting the BACS modules:
With wrong handling, the integrated fuse is sensitive and may trigger.
BACS bus cable
The patented BACS bus allows high-speed communication between all BACS
modules within a battery system. This cable is specially designed for use with
BACS only. It is shielded and calibrated against EMI to ensure communication even
in harsh environments.
Before you start …
like the CS141, when using BACS there are many things that should be considered before starting an installation - there are many
individual installation options to be used. One of the most Important thoughts coming with this context, is whether and how to extent the
technical possibilities of existing systems. Eine der größten Probleme ist hierbei, dass unter Umständen völlig unterschiedliche Systeme
miteinander koordiniert werden müssen, um gemeinsam auf dasselbe Ziel hinzuarbeiten.
One of the biggest problems is that different systems may have to be coordinated with each other in order to work together. In fact, the
BACS system makes it easy to be added:
It does not care whose batteries should be managed unless different UPSs are combined to charge the batteries - this should be
avoided, because a BACS Web Manager will expect one UPS for the connected batteries is responsible. Otherwise the measurements
are strange and not suitable analyses. However, as long as this framework condition is met, it would be a quite useful information if the
UPS could communicate its own operating state, but it is not needed.
Due to this fact, a BACS system can be fitted seamlessly into almost any infrastructure in order to manage the batteries The
Central task of BACS inside an existing infrastructure
In addition to the monitoring of the battery conditions, the central task is care and active regulation of the batteries during the complete
charging / discharging cycle. Thereby BACS takes into account the needs of each individual battery in relation to the overall system in
order to ensure improved lifetime as well as maximum performance if an emergency situation occurs.
For the operation of BACS, it is not important to know UPS that will charge the batteries or which discharge circuit will be used - as a
standalone sytsem, BACS can detect the basic system states with its own sensors inside eacht BACS module:
- charge status
- discharge
- trickle charging status
