Samsung SDI (Seoul, South Korea) launched
its new energy storage (ESS) products that adopted innovative design
technology at Energy Storage Europe 2017, an international exhibition
held for three days from March 14th, 2017 in Dusseldorf, Germany.
The company showcased new ESS products at
the exhibition, high-capacity E2 and high-power P3 models, whose energy
density is sharply increased.
E2 model is a high-capacity ESS battery that
substantially increased the number of cells integrated in the container
by adopting innovative design technology.
Samsung SDI dramatically raised intensity of space
in the ESS container by upgrading module design and rack arrangement
technology, the company notes.
The company designed a compact module by reducing
its size from 42 liter to 35 liter, while configuring it to increase the
number of integrated cells in the module by 10% from 20 in previous
modules to 22 cells.
Its design is innovated to integrate larger number
of cells in a smaller space. And the container is designed to enclose
larger number of ESS modules by adopting a new rack arrangement method
that removed passages in the ESS container.
The company prevented any problem in managing ESS by
adopting improved cooling technology and installing gates on both sides
of the container while removing passages.
As a result, E2 model realized the high-capacity ESS
battery by enclosing the capacity of 9.1MWh in the container, nearly
twice larger than previous products.
E2 model is developed targeting utility ESS markets
that requires large capacity. Needed for storing energy during
low-demand hours and using it in high-demand hours, utility ESS
batteries are widely used in recent years in connection with renewable
energies such as solar photovoltaic power and wind power. As a utility
ESS with larger capacity can store more energy, it can supply energy to
larger number of facilities.
Samsung SDI also unveiled P3, a further upgraded
high-power model. P3 is designed to maintain high-power for longer time
by using 78Ah high-power and high energy density cells with 15%
increased capacity without changing the size of 68Ah battery cells
adopted for previous models. P3 model can be used for power
stabilization that requires high-power ESS.
The common feature of E2 and P3 is that their energy
density is improved by increasing capacity while retaining the size of
previous ESS containers. ESSs with increased energy density can save
construction and facility management costs by reducing scale of ESS
facilities. Eventually, this will lead to reduction in investment on the
part of customers.
In addition, Samsung SDI displayed two new
residential ESS modules. One of them is an advanced lithium-ion ESS
battery that can replace previous lead-acid battery by adopting a
technology of delivering 48V, the same voltage as the lead-acid battery.
The other is an ESS product that can reduce cost of ESS system by
providing high voltage.
“The new lineup further sharpens competitive edge of
our ESS products. We will lead the world market by developing advanced
ESS technologies ahead of others,” said Sewoong Park, vice president for
ESS Team, Samsung SDI.
