Lithium battery for low- and also high-voltage storage

• Dubai-based Weco has actually introduced a new lithium battery solution that can operate in parallel as a low-voltage storage space system or in series as a high-voltage battery without hardware changes. The batteries can be mounted on wall surfaces or set up in a pile setup.

Weco, a battery supplier based in the United Arab Emirates, asserts its new lithium battery option can run in parallel as a low-voltage storage system or in series as a high-voltage battery, with no hardware modifications.

The 5K3 LV/HV battery pack can deal with both low- as well as high-voltage inverters thanks to a dual circuit and also an embedded battery monitoring system that runs without the demand for an extra battery monitoring device.

The battery can be deployed as a wall-mounted option or in a stack setup, as well as the systems are simple to install, thanks to a special unit, the producer claims. "The internal components are safeguarded by a tough steel situation which can be wall surface placed, self-standing on the flooring, or piled, providing the individual the optimum versatility," Giorgio Tibolla, the business's sales supervisor for EMEA, told pv magazine. "The battery module can be adjusted to various sort of rooms."

Tibolla stated the battery, when it should run in low-voltage setting, can be attached in parallel to form a low-voltage system with up to 25 batteries, providing for a storage capacity of as much as 130 kWh. In high-voltage mode, the storage systems be connected in series to create a cluster with an optimum voltage of 940 V (DC), with the collections stacked in nine towers, giving a storage ability of as much as 620 kWh.

The company's managing supervisor, Donald Anderson, claimed the battery is compatible with around 25 various inverter methods and also can be attached immediately with many low-voltage and high-voltage crossbreed inverters in the market.

Each battery unit has a storage capability of 5.2 kWh, with overall measurements of 450 mm by 510 by 155 mm as well as a weight of 50 kg. The lithium-ion system uses LiFePO4 as the cathode product as well as has an ambient operating temperature level variety of -20 C to 45 C.

"The lithium cell technology inside the 5k3 LV/HV component utilizes WeCo's maximized chemical composition to give the best efficiency as well as greatest variety of cycles," Anderson stated.

Nanographene made use of in the chemical remedy adds to the security as well as period of the LiFeP04 chemistry used in the battery, the manufacturer claims.

Weco currently runs a production line in China, as well as will certainly activate an additional assembly line in the 3rd quarter at its center in Florence, Italy. "The very first set will certainly be sold in Italy as well as throughout Europe from July 2020, yet from November the brand-new 5K3 will be offered additionally in U.S., Australia and South America," Tibolla claimed.

Tibolla added that the price of the battery is in line with existing single-voltage devices. Its main benefit is that the exact same battery can be made use of for both residential or commercial demand, and can be related to both reduced- and also high-voltage tasks, he stated. The systems additionally include Wi-Fi connection to allow for real-time surveillance by means of WeCo's proprietary application.
