Many thanks to Opel, that they made avaivable the auditorium in Rüsselsheim. And for the presentation of the Opel Monza Concept, as well as other interesting cars.
The high voltage accumulator
Our high voltage accumulator consists of 192 LiPo cells from the manufacturer Melasta Ltd. assembled in a 96s2p configuration. The nominal energy content is 5.63kWh at a total weight of only 48kg, holding system included. One stack consists of 24 cells in a 12s2p configuration, of which we have eight in our accumulator. We want to thank ASP Lasertechnik a lot for laser welding our cells. We also want to thank AVG Oberflächentechnik very much for the nickel coating of our aluminium busbars and also thank Müller Ahlhorn GmbH. for sponsoring the fireproof and nonconductive Macrolon for our accumulator housing. Thanks a lot also to ISW Wiesbaden Technik for gluing the housing. Our self designed BMS system monitors our cell temperature and voltage steadily and is able to react very quickly in cases of danger through our generic can bus.
We are all already very excitedly thinking of the performance test. We are going to test charging and discharging at maximum permissible values of the cells and check the temperatures of the cell and busbar connections using an IR camera. We will also test all safety electronics like the pre- and discharge system and the emergency circuit.
After a few exciting minutes we have been informed that we made it to be one of the participants at the Formula Student Germany 2014 event.
The event takes place from July 29th to August 3th in Hockenheim.

New pump for the cooling system: We want to thank our new sponsor VOVYO Technology Co., Ltd. for the new high power cooling fluid pump. By using this new and high power 50W pump we reach a 50% lower weight compared to the last years pump. We also higher the flow rate and by the way also the cooling power of our system. Through a customized control we are able to manage the speed of the pump by using an analog.
