pv magazine Webinar | Raising the bar on battery energy storage safety

Lithium-ion batteries are generally safe and not subject to failure, when properly
certified and properly installed. Batteries used in stationary storage applications are subject to continuous innovation at material, cell, and system level. These innovations come with a host of advantages, such as higher energy density, however, they also require upgraded safety features to compliment them.

Lithium-ion battery energy storage systems are a key enabler of the global energy transition, but some high-profile incidents have heightened the concerns of some regarding their safety. Against the backdrop of tremendous amounts of engineering efforts to make the batteries more powerful and versatile, safety features are also evolving rapidly to ensure the safe deployment of these important assets.

Many manufactures have already moved away from 280Ah cells to offer 300Ah+ cells.
These higher capacity cells ensure higher capacities at the container level with average capacities rising from less than 4MWh to more than 5MWh in the same 20-foot-equivalent containers. This makes it possible to install more energy in a smaller footprint and thus save on real estate and land usage.

Furthermore, a smaller number of cells per MWh reduces assembly and packaging which enhances efficiency during production processes. However, large cells do pose a greater challenges for management systems particularly in terms of consistent and adequate heat dissipation.

In this pv magazine webinar, we will discuss the latest battery energy storage system design trends along with addressing the perceived safety concerns.
Neill Parkinson, Product and Business development Manager (BESS) for Jinko
ESS, will be joining us to share insights into the manufacturer’s latest technology upgrades and safety strategies.

Together we will take a closer look at Jinko’s latest Utility-Scale battery storage innovation – SunTera. The system boasts not only an upgraded capacity of 5 MWh with the introduction of the new 314 Ah battery cells but also offers a range of accompanying advancements at all levels, such as high charge and discharge efficiencies. Jinko ESS puts safety at the heart of its designs with multiple levels of protection and insulation to avoid cascading system failures.
