Toshiba has developed a battery that can be used with PV modules, with a design that charges and discharges at high currents. The new SCiB 20 Ah-HP product has a nominal capacity of 20 Ah, a nominal voltage of 2.3 V and an input power of 1900 W. It measures 116 mm x 22 mm x 106 mm and weighs 545 grams.

Japanese Toshiba has launched a new rechargeable lithium-ion battery for automobiles, industrial equipment and storage battery systems.

“The battery can also be used with solar power generation,” a company spokesperson said. pv magazine. “The new 20Ah-HP cell is particularly suitable for charging and discharging at high currents, such as when used in conjunction with renewable energy sources, which have large output fluctuations. For this reason, we believe it is suitable for applications that require response to large output fluctuations and high frequency charging and discharging, such as when frequency control and peak offset/peak cutoff are used together.

The new SCiB 20 Ah-HP product has a nominal capacity of 20 Ah, a nominal voltage of 2.3 V and an input power of 1900 W. It measures 116 mm x 22 mm x 106 mm and weighs 545 grams.

Toshiba said the new product eliminates the cost of battery replacement. He claimed the offering is superior to other batteries in terms of total cost of ownership (TCO) over the entire product lifecycle.

“In general, when solar power generation systems are combined with storage batteries, the problem is that the storage batteries have a shorter life than the solar power generation system, so the storage batteries should be replaced halfway through the useful life of the solar system,” the company explained. “The new product has even better life performance than the existing product, eliminating the need to replace batteries as their capacity deteriorates.”

He said the battery cell was designed for heavy-duty applications where high power input and output is crucial, where battery cells need to remove heat and operate uninterrupted to facilitate rapid charging of commercial vehicles. , regenerative power systems for rolling stock and industrial equipment. .

“The cell is the same size as Toshiba’s current 20Ah product, allowing current customers to easily upgrade to improved input and output power with the same module pack,” Toshiba said. “Compared to Toshiba’s current 20Ah cell, the new 20Ah-HP cell provides 1.7 times higher input and 1.6 times higher output, thanks to an approximately 40% reduction in resistance in the cell.”
