Daimler AG takes a brilliant move to chase Tesla Motors The batteries will come in 2.5kWh and 5.9kWh versions. MB will announce costs next month. MB seems to be copying Tesla by venturing into energy storage, perhaps as an attempt to grab some market space early enough, especially at home. Germany is one of the best markets for energy storage due to high solar uptake. Operating on a home turf may give MB some advantage over Tesla Energy. I am curious about MB plans to remain competitive in this space without actively working on driving down battery costs in a similar manner that Tesla is doing. Perhaps MB plans to keep buying cells from Tesla/Panasonic and just add value by integrating cells in a plug in storage unit.
