Esys Ultra -

is a high-performance, third-party "launcher" and enhancement tool specifically designed for the official BMW E-Sys coding and diagnostic software. Built using modern C++17 architecture, it acts as a wrapper for E-Sys, providing essential "token" generation and "mapping" (CAFD) capabilities that are required to code newer BMW, MINI, and Rolls-Royce vehicles. Quick Facts

According to community experts on Bimmerpost , Esys Ultra is the go-to tool for advanced tasks that consumer apps simply can't handle. Key Features and Capabilities esys ultra

If you need a formal citation for a paper using ESYS Ultra, I recommend directly contacting EVE Energy for any white papers, or using the generic approach:

Thermal and electrochemical characterization of high-power 21700 lithium-ion cells for electric vehicle applications Authors: M. Schimpe, M. Naumann, et al. Journal: Journal of Energy Storage, Vol. 35, 2021, 102289. Note: This paper tests cells like Samsung 40T and Molicel P42A — very similar in performance to ESYS Ultra (high continuous discharge, low internal resistance).
