2.3 Battery Management System (BMS)
The Battery Management System integrated in each LiFePO4 battery monitors and protects the
battery from damage due to improper handling or incorrect parameters. In addition, the BMS
performs an active internal cell balancing to always maintain maximum performance.
In detail, the tasks of the BMS are:
• Protection against overload due to excessive charging current or excessive discharging current.
• Protection against excessive charging voltage or overvoltage
• Protection against too low a discharge
• Protection against overtemperature
• Protection against short circuit
• Automatic cell balancing (equalisation of the individual cells in the battery to be at the same
charge level)
If one of the aforementioned protective devices causes the cells to be switched off and thus dis-
connected from the terminals, no voltage can be measured at the pole connections. If the reason
for the disconnection no longer occurs, the battery switches on again automatically. Switching
on again after protection against too deep a discharge can take up to several hours.
3. INSTALLATION
3.1 General
• Please check the battery for external damage before installation. If there is visible damage, do
not install or operate the battery, please contact your vendor immediately.
• The battery must always be operated with an appropriate external fuse in the consumer circuit.
• The battery can be installed in an upright, standing or lying position.
• The battery must be firmly and securely installed in the vehicle or system, in motorhomes the
existing mounting can very often be used.
• The connection poles and terminals must be covered after installation to protect against short
circuits, existing round pole terminals can be used.
• Never connect batteries with consumers switched on to avoid sparking.
• Do not expose battery to direct sunlight and install indoors, do not install near heat sources.
• Charge before commissioning, during transport the battery is only charged to 40-60%.
