the most stringent access? TOP10

Germany is the largest household storage market in Europe.

In 2022, the total installed capacity of German household storage is about 220000 units, accounting for 47% of the total installed capacity in Europe. In the first half of 2023, Germany's household storage capacity was 250000 units, up 170 per cent year-on-year.

Germany is a global highland for the commercialization and standardization of energy storage applications, with more stringent standards than elsewhere.

Germany is almost the world leader in energy storage applications, quality control, technology research and development, and the development of safety standards for energy storage systems.

VDE-AR-E 2510-50 is a standard developed by the German Electrical and Electronic Association (VDE) specifically for the safety of lithium-ion energy storage. This is currently the world's first standard for comprehensive evaluation of energy storage.
