Saft launches a higher voltage (56 V) Li-ion battery option in its Xcelion line

Saft battery

Saft launched a new product in the Xcelion line, the Xcelion 56V lithium-ion (Li-ion) battery, offering customers a variant on the proven technology behind the Xcelion 6T for applications requiring higher voltage.

As the third Xcelion product, the Xcelion 56V builds upon the existing technology behind the Xcelion 6T, launched in 2015, and the Xcelion 6T-E, a high energy Li-ion battery launched in 2018 that doubles the capacity of lead-acid batteries in the same form factor, allowing customers to take advantage of volume production. The Xcelion 56V offers higher capacity, a longer life cycle, longer calendar life, lighter weight, and smart battery capabilities compared to standard lead-acid batteries. The 41Ah Li-ion battery is an off-the-shelf solution with a nominal voltage of 52.8V and is only half the weight of lead-acid batteries of similar size.

The Xcelion 56V also includes standard safety features such as abuse-tolerant Super-Phosphate Li-ion technology and a battery management system. Smart battery features enable communication with the end user, providing information about the battery state-of-health, state-of-charge, and other functions. Applications for the Xcelion 56V include military ground vehicles, defense, microgrids, solar power systems, electric vehicles, and other applications using 48V power.

Saft also has plans to launch an Xcelion 6T Li-Type 1 battery at the end of 2019.

SolarEdge to offer its own battery as part of full storage solution, among several product portfolio updates

SolarEdge

Word out of Intersolar Europe is SolarEdge Technologies is expanding its StorEdge solution with the launch of new inverters optimized for the combined management of solar, storage, and home energy. The StorEdge expansion will include three new additions to the solution portfolio, plus the company will preview its own commercial and residential batteries to complement its smart solar energy portfolio.

In June 2019, SolarEdge will introduce to the market a single phase inverter with HD-Wave technology that integrates the management of solar, storage, and home energy into one inverter. The combination of all of these functions into one inverter will simplify installation, improve system RoI, and increase self-consumption.

A second enhancement to StorEdge is the planned addition of a three phase inverter that can be DC coupled to one or more 48V batteries to support the growing European solar-plus-storage residential market.

The third addition to be showcased at Intersolar are the SolarEdge commercial and residential batteries, which will be added to the StorEdge offering in order to provide a comprehensive storage solution. Committed to providing flexible solar-plus-storage installation options, SolarEdge batteries are expected to be available worldwide in the beginning of 2020 and the company will continue to support StorEdge’s compatibility with multiple battery vendors.

“As the evolving solar energy market focuses on increasing self-consumption and grid stabilization, PV-plus-storage solutions are becoming a critical factor in the proliferation of smart solar energy ecosystems,” stated Lior Handelsman, SolarEdge’s VP of Marketing and Product Strategy, Founder. “By expanding StorEdge and adding batteries to SolarEdge’s core offering, we will provide a seamless energy experience for both installers and system owners.”

The addition of commercial and residential batteries to its StorEdge offering will allow SolarEdge to offer an end-to-end, compatible storage solution that fully synchronizes PV, battery, and site-level energy management. The Li-Ion, high-voltage NMC batteries will offer energy management by stacking multiple value streams, including demand management (peak shaving), both site-level and aggregated self-consumption maximization, ancillary services, tariff optimization (ToU), in addition to supporting micro-grid applications. As the batteries are designed for full compatibility with StorEdge, the planning, design, installation, service and warranty process are designed to be significantly simplified. The batteries will be able to be either AC or DC coupled with StorEdge, with DC coupling allowing for superior efficiency and PV oversizing.

Morningstar’s Energy Storage Partner Program keeps growing, now includes specs for 12 battery providers

Morningstar Multiwave

At one of the solar industry’s most respected events — the North American Board of Certified Energy Practitioners education conference — Morningstar Corp. announced that its Energy Storage Partner Program (ESP) has more than doubled in size since being introduced just last September.

Morningstar launched the ESP program to make it easier for solar professionals to specify lithium batteries into new systems or drop them into and upgrade existing ones. Initially including five leading advanced battery brands – Discover Battery, NEC Energy Solutions, PowerPlus Energy Solutions, RELiON, and SimpliPhi Power -ESP eliminated the uncertainty and “lithium anxiety” for installers by doing their homework in advance.

How Morningstar designed its software-first solar inverter for the lithium battery age

All critical settings required for switching a system’s electronic control over to lithium-iron phosphate (LiFePO4) chemistry were determined in advance, between Morningstar and the battery brand partner. Installers no longer needed to “ping pong” between a battery manufacturer and a solar system component manufacturer to get the information they needed – ESP provides it up-front in verified documentation. All the installer has to do is access the documentation free of charge, saving them considerable design and set-up time.

Based on its initial success, the next wave of battery partners has joined Morningstar’s ESP program. They include: Trojan Battery, Pylon Technologies, Dragonfly Energy, KiloVault, Blue Planet Energy, Battle Born Batteries, and Lithium Werkes BV.

Lead-acid replacement Tydrolyte named an emerging battery technology by a national battery organization

tydrolyte lead acid battery

Tydrolyte has been selected as one of the top emerging battery technologies of 2019 by the National Alliance for Advanced Transportation Batteries (NAATBatt). The novel electrolyte is a less toxic drop-in replacement for sulfuric acid in lead batteries that enables significant performance improvements.

Lead acid batteries are the oldest and most widely used rechargeable battery technology globally with unsurpassed advantages in cost, reliability and sustainability. Tydrolyte test results show significant improvements in critical lead battery performance metrics enabling longer operating life and improved lead battery economics for both manufacturers and users.

Boris Monahov, a lead battery technology expert and a member of Tydrolyte’s Advisory Board, has called Tydrolyte “one of the most significant technical advancements in the 150-year history of lead batteries.”

Tydrolyte LLC will be among ten featured companies to present at the Battery Innovation Summit during NAATBatt’s annual meeting and conference in Phoenix on March 14. Featured companies were identified by the battery organization as having the most promising new battery technologies available in 2019 for licensing, investment or acquisition.

Lead acid batteries continue to be the dominant global rechargeable battery technology with over 600GWh shipped annually. As a drop-in replacement for sulfuric acid, Tydrolyte can be adopted easily in existing factories without requiring new equipment or process changes. The electrolyte increases battery life, battery efficiency, and charge acceptance—all critical performance parameters needed for stop/start and mild hybrid vehicles, industrial applications, and stationary grid storage. The global lead acid battery market is expected to reach $84.46 billion by 2025, according to market research firm Grand View Research, Inc.

Tydrolyte CEO Paul Bundschuh said the company has signed testing agreements with several of the largest U.S. and international lead battery manufacturers which are evaluating Tydrolyte in their batteries.
