Samsung SDI Unveils Modular EV Batteries at Frankfurt, Eyes Tesla
Samsung SDI introduced a modular battery pack and a new 21700 cell at the 2017 Frankfurt Motor Show, aiming to challenge Tesla’s lead in EV battery technology.
Samsung SDI presented its latest electric vehicle battery technology at the 2017 Frankfurt Motor Show, including a modular battery pack system and a new cylindrical cell designed to compete with Tesla’s approach. The company’s stand focused on flexibility for carmakers and a direct challenge to the Californian EV leader.
Modular battery pack targets diverse EV needs
The centrepiece of Samsung SDI’s Frankfurt display was a modular battery pack system. The design lets manufacturers vary the number of modules in a pack, offering a flexible solution for different vehicle types and price points. According to Samsung, a premium car with 20 modules could achieve between 600 and 700 kilometres of range. For a standard saloon, reducing the pack to 10 or 12 modules would provide around 300 kilometres. The system aims to help carmakers tailor EVs to specific market segments without developing entirely new battery architectures.
Alongside the modular concept, Samsung SDI displayed a new “Low Height Cell”, which is 20 percent shorter than existing cells. This allows manufacturers to free up interior space, a practical advantage for packaging and cabin design.
Direct competition with Tesla’s battery technology
Samsung SDI’s new 21700 cylindrical cell mirrors the format Tesla uses in its Model 3 and energy storage products. The 21700 cell measures 21 millimetres in diameter and 70 millimetres in height, offering roughly 50 percent more capacity than the older 18650 format. By adopting this standard, Samsung SDI positions itself as a direct competitor in the supply of high-capacity EV batteries, particularly as more automakers look for alternatives to Tesla’s in-house production.
Production and supply outlook
Samsung SDI’s battery manufacturing footprint covers Hungary, Ulsan in South Korea, and Xian in China. The company opened its Hungarian plant in May 2017 to support growing European demand for electric vehicles. This expansion signals Samsung SDI’s intent to supply a broader range of global automakers as the market for EVs expands.
With the modular pack, the low-height cell, and the 21700 cylindrical format, Samsung SDI is positioning itself as a flexible supplier for the next wave of electric vehicles. Its challenge to Tesla comes as automakers seek more battery sourcing options for their future EV line-ups.
