4.1.2 Temperature Variation
Maintaining temperature balance across the string is very important for maximum battery life.
Excessive temperature variation will result in the need for equalisation and will shorten battery
life. Sources of battery temperature variation can be the placement of the battery system near a
heat source such as radiators, power equipment, windows or heating vents. Air conditioning vents
can also cause temperature variations. It is recommended that the battery location be designed,
engineered and monitored to minimise temperature variations.
4.1.3 Ventilation
Proper ventilation of VALEN ENLiFEN Batteries is important for two reasons:
1. To minimise battery temperature variations and
2. To reduce the possibility of prematurely triggering the over-temperature sensor.
4.1.3.1 Ventilation & Battery Temp. Variation
Charging and discharging VALEN ENLiFEN Batteries gives off a small amount of heat. Proper
ventilation is important to remove this heat and to prevent temperature differences from arising in
the enclosure. If the VALEN ENLiFEN Batteries are installed in a client’s own enclosure, it should
be designed to allow unobstructed air circulation and prevent temperature build-up. Sufficient air
circulation should be present to prevent temperature-layering effects. In an improperly designed
room, there can easily be a 5°C difference in temperature between the floor and the ceiling.
4.1.3.2 Gassing
Unlike VRLA batteries, VALEN ENLiFEN Batteries do
NOT
emit any gas during normal charging and
discharging. However, ensure some air exchange is present in the ventilation.
4.1.4 Floor Loading
Whilst this is not quite as severe a problem as with VRLA batteries, before installing the batteries,
it should be ascertained that the floor can support the weight of the battery rack or cabinet and
related equipment. The total system weight will be the sum of the batteries, rack or cabinet plus 5%
for the battery connectors and cables. It is the responsibility of the installer to ensure adequate floor
load loading capabilities.
4.2 Seismic Considerations
VALEN ENLiFEN Batteries are capable of withstanding seismic events of UBC Zone 4 magnitude
when properly installed in a suitably designed cabinet or rack. When the seismic capability is
desired, suitable floor anchoring should be provided. Proper floor anchoring is the responsibility
of the installer. Ensure that the anchors used are of sufficient strength to withstand the maximum
seismic load foreseeably.
4.3 Unpacking
VALEN ENLiFEN Batteries are shipped on pallets with cells/modules in the vertical position. All
accessories needed for installation and use are packed in boxes and shipped on top of the modules
or a separate pallet. Unpack all items carefully and note the quantities received.
4.4 Installation
CAUTION! Remove all jewellery before installing the connectors on the batteries. Ensure that all
tools are correctly insulated to prevent shorting. Do not reach or lean across batteries. Remember,
hazardous voltages may be present. Be aware of what you are touching at all times. Do not rush,
take your time
