If the number of electric vehicles (EV) increases in the near future, the situation of parking lots combined with public charging stations will steadily become more difficult in urban and suburban areas. Not all EV drivers have the opportunity to charge their EV privately e.g. by using a Homecharger. This Problem can be solved, if light electric vehicles (LEVs) operate with portable batteries, in order to enable a battery charging as flexible as possible. Therefore the LEV should offer the option to recharge on-board by wire as well as external charging, for example at the apartment or office, due to the battery portability. Compared to usual EVs, the battery capacity and thus the size and weight of LEV batteries are smaller and lighter, which facilitates a portable battery concept. For the development of a portable battery concept, a lot of factors have to be considered for a user-friendly fitting and removing of the batteries such as weight, size, shape, but also installation space, height, and position. Furthermore, a lot of requirements like health protection, ergonomics and technical design have to be taken into account. Within this project, all these factors were researched and moreover a portable battery concept was developed. Additionally three different prototypes of battery packs were engineered and built with additive manufacturing.
