ESS Technology
Improved battery performance for evolving UPS, solar and telecommunication
networks
The operating conditions of modern UPS and telecommunication networks are driving the
development of VRLA batteries and pushing the limits of such back-up systems. HOPPECKE one
of the most innovative battery manufacturer in the world, is pushing back with the improved
product ranges power.com XC, power.com HC, power.com SB as well as the front access version
net.power.
power.com HC / SB / XC net.power
Products designed and manufactured with brand new HOPPECKE ESS technology ensure a
lower sensitivity of VRLA batteries against the harshest environmental operating conditions.
The risk of thermal runaway, a well known phenomenon at AGM batteries, is nearly eliminated by
this technology, which allows a higher flexibility for compact battery arrangements on racks or in
cabinets. It promotes further the conductivity between the electrolyte and active mass with the
benefit of a limited voltage spread as well as an improved charge acceptance over the entire life
time. Service costs caused by equalizing charges can therefore be reduced to a minimum.
Today’s telecommunication networks claim for higher cycle ability exceeding values of standard
AGM batteries, but keeping the electrical performance. Measurements on HOPPECKE AGM
batteries with ESS technology attest a significantly higher cycle life overmatching the base AGM
technology by more than 20%. Latest manufacturing technologies and continuous process
improvements engineered and controlled by German quality standards set HOPPECKE products
apart from the mass market and emphasize the quality demand of a premium manufacturer as
well as our ambitious customers.

ESS - Technology characteristics
Figure 1 shows the temperature development of
a power.com battery at 160 hours overcharging
with 2.65 V per cell. Standard AGM batteries can
be affected by a thermal runaway under these
operating conditions with a temperature rising of
up to 100°C. The minimized sensitivity against
overcharging limits the risk of hazardous
temperature deviations within compact battery
strings, assembled on racks or in cabinets.
HOPPECKE ESS technology promotes more
flexibility in the battery assembly while exhibiting
none of the disadvantages of standard AGM
batteries.

Solar applications as well as telecommunication
networks require more and more cycling abilities
exceeding values of standard AGM technology.
Figure 2 shows an extract from an ongoing cycle
life test acc. DIN EN 60896-21. After already 400
cycles with 40% DOD the final discharge voltage
still remains clearly above the test criterion of
10,8V respectively 1,8 V/Cell. With regard to the
suboptimal cycling conditions related to float
charge and prescribed at DIN EN 60896-21, it
can be derived that the brand new HOPPECKE
ESS technology will provide even more than 1000
cycles.
