|Can I install my Aquion stack or module outdoors? What do the IP ratings mean?|
Our stacks and modules are designed for indoor installation. While many of our electrical connections are watertight, some pooling of water can occur on top of the battery stacks as
|What external charger can I use?|
Any 48V charger with current protection should work. We have had good results using the Mean Well PB-300-48 for stacks (http://www.mouser.lu/ProductDetail/Mean-Well/PB-300P-48/?qs=%2fha2pyFadugf8o20W%2fqko4A030oglD8kUUmbwOFGAOBkpMuFTccPYg%3d%3d) and the Mean Well PB-1000-48 for the modules (http://www.mouser.com/ProductDetail/Mean-Well/PB-1000-48/?qs=sGAEpiMZZMsYfYypWaYaEYPGUDGdiaA6jRfzMw%252bIRD0%3d)
|Adding new batteries to an existing bank|
With Aquion, there is no safety hazard when mixing new and old batteries, however, the new batteries will perform as good as the old ones.
|What is the Job of the BMS?|
The Aquion Battery Monitoring System (BMS) gathers voltage, current, and temperature information from each individual modules, VIS (voltage-current sense) board via CANBUS communication protocol. With this data, the BMS
|Tip and Tell (Tilt Angle)|
S-Line and M-Line batteries should be shipped in an upright position and should not be tipped for an extended period of time during shipping.During movement to the installation site and
The power going to or coming from the batteries can be ramped up or down instantaneously; there are no specific requirements for charge and discharge rate as long as the
|Parallel (Low Voltage) Configurations|
Aquion batteries can be arranged in large parallel configurations for the following reasons: The high impedance and overall uniform impedance of the battery makes parallel current sharing more feasible -
|Inspectors Looking for UL certification|
UL certificates for Aquion batteries are available here: http://database.ul.com/cgi-bin/XYV/template/LISEXT/1FRAME/index.html
|End of Life|
End of life is considered a loss of 30% of a battery’s original capacity. The batteries do not experience a “death” at that point. They can be cycled further with a reduction of capacity.
|Battery Balancing (Self-Balancing) & BMS|
Other battery chemistries require battery equalization, hence the need for a BMS or string size limitations. The AHI chemistry does not require balancing and is considered to be self-balancing. Although
For S30 and Aspen 48S-2.2, short-circuit
current peaks at 140A, then levels at 120A per stack.
|How Many Modules Can I Connect to 1 BMS?|
The Aquion Battery Monitoring System has been designed to track up to 16 modules. It can be used with a single module as well.
|Are there any special materials required to extinguish a fire?|
No, Aquion batteries, while highly unlikely to be the root cause of a fire, do not require special material to extinguish - water is fine.
