Ratings KingsCrowd Startup Rating Methodology Article

Analyst Report Analyst Report Methodology Article

The most common method for short-term energy storage is the lithium-ion battery. There are so many lithium-ion battery startups on the market that it’s hard to keep up. But Joule Case is different from most of the solutions I’ve encountered. 

Its batteries are portable, stackable, and range in size from small 500-watt batteries to container-sized 540-kilowatt batteries. They can be charged with solar panels — which most customers do — or just plugged into the grid. Joule Case’s batteries are separable from the plug and buttons, so customers can connect them together like Legos depending on their needs, using more batteries for more energy. Joule Case’s modular and portable features are a distinctive — and patented — technological advantage over alternative solutions.
