Where can I buy BattEQ?
Contact one of our distributors. If you would like to become a distributor, contact us.
Can the switched-capacitor based BattEQ move sufficient current to be effective?
Yes. BattEQ has already been proven to move sufficient current to equalize very high capacity batteries. SmartSpark has invested heavily in optimizing its patented technique. Any source to the contrary is very unlikely to have properly designed the circuit as to make a valid claim.
Is BattEQ limited to single-unit implementation?
No. BattEQ is sufficiently modular such that all equalization cells can be implemented as one unit, or each unit can be implemented separately. SmartSpark will provide custom packaging to suit any customer's needs.
Can I use multiple BattEQ units for longer strings?
Yes. As just one example, two four-cell (48-V) BattEQ units could be overlapped to cover seven cells (84 V).
How much battery life improvement will I get?
The answer depends on many factors that vary from application to application. BattEQ generally provides the most benefit in deep, repetitive cycling applications such as electric vehicles. However, it has also shown significant cost benefit in mild applications such as telecommunications backup power supplies. SmartSpark will work with you to determine your cost-benefit.
How does BattEQ save me money?
BattEQ reduces the number of battery replacements. This saves on battery cost, labor, downtime, inventory, hassle, and in some cases, truck rolls. Often labor and downtime are even more expensive than the batteries themselves.
Does BattEQ work with battery chemistries other than lead-acid?
Yes, it has been shown to work well with Li-ion batteries and is under test with NiMH batteries. This is very important for Li-ion since overcharge equalization does not work and Li-ion cells are much more expensive than lead-acid. Essentially the same BattEQ unit suffices for any battery chemistry.
What benefit does BattEQ provide to ultracapacitors?
Ultracapacitors in series strings generally become imbalanced immediately due to tolerance and differences in age. This could result in overcharge and destruction of the capacitor bank. Furthermore, since BattEQ guarantees all voltages are held equal and capacitor lifetime is a strong function of voltage, the lifetime of the capacitor bank is maximized.
Where can I get more information or prior data?
See the applications and publications sections.
