Renault Fluence Z.E. were deployed in Israel and around 400 units sold in Denmark through May 2013, when Better Place filed for bankruptcy. Since 2011 a total of 3,935 units have been sold worldwide through October 2014. The Fluence Z.E., called SM3 ZE in South Korea, is the most numerous electric car of the South Korean car parc, with 1,604 SM3 ZE sold till December 2015. Approximately 6,000 Renault Fluence Z.E. have been sold between 2011 and 2015. The lithium-ion battery has a capacity of 22 kWh and weighs . The Fluence Z.E. is longer than the internal combustion model to accommodate the
Latitude of the Gulf Stream and the Gulf Stream north wall index analysis was then used to find the pattern of variation common to the six longitudes. This is preferable to simple averaging of the six latitude estimates which would emphasise the eastern longitudes where the north-south movements are largest, and possibly obscure smaller but coherent north-south shifts further west. Correlation coefficients are calculated between the six time-series and the principal components are the eigenvectors of the resulting correlation matrix. (Empirical orthogonal function analysis proceeds instead from the variance-covariance matrix which again is biased to the eastern longitudes.) Each principal component is calculated as a weighted average of the standardised latitude series
