Overview

Traffic congestion is a major problem in densely populated megacities such as Jakarta, travelling from point A to B is very inconvenient especially for the working class. Regular taxis are comfortable, but run the risk of being completely held up by the traffic congestion. Two-wheelers while able to weave through traffic and reach their destination faster; do not offer the same level of comfort and environmental protection as regular taxis. A vehicle combining both safety and comfort of a car with the agility of a two-wheeler would therefore be very beneficial, but is currently not readily available.

MAE and TUM (Technical University of Munich) students jointly develops ‘VOI’ or elephant in Vietnamese which signifies safety, ecological friendliness and comfort. Equipped with a front passenger pod, the electric powered two-wheeler serves as personal transporter or taxi, allowing the passenger a speedy commute through heavy traffic while shielded from the elements. When needed, the passenger pod can be swapped for a cargo carrier or mobile food stand.

Awards and Achievements

VOI team won the Land Transport Excellence Award 2014 in the “Young Innovator” category during the biannual award ceremony on 17th April 2014. This award recognizes the individual/s who has delivered innovative products or services resulting in land transport transformation. Land Transport Authority (LTA) launched the inaugural Land Transport Excellence Awards in 2008 to celebrate the best in the land transport industry who demonstrate commitment and dedication towards Singapore's vision of a people-centered land transport system.

Design

The anthropologic dimensions of Singaporeans and Indonesians are used to determine the package. Thus 95th percentile of Indonesian men (1.83 m) is considered as the tallest allowable passenger sitting in the cabin.


Prototyping

VOI Prototype

 

The passenger cabin is made of CFRP, allowing a light and very stiff monocoque. In order to achieve a comfortable entrance and exit for the passenger, the module employs a front-flip mechanism, hinged on the front, which enables the entire enclosed structure to be lifted up.


Energy Storage

VOI battery system

The 48 V battery box includes 13 battery modules with 20 Panasonic lithium NCR 18650A cells each and has a capacity of 3 kWh. Thermal measurements have been carried out to investigate the heat transmission that occurs during the discharging process.


Conclusion

The presented features, amongst others, will lead to a vehicle perfectly fitted in developing tropical megacities. VOI aims to be able to take passengers as well as cargo quickly and safely though the traffic with its short wheelbase and ability to transport heavy loads. This would fit perfectly in cities like Jakarta. Maintaining the idea provide comparable level of comfort and safety as a car for the passenger, and as agile and economic as a scooter for the driver, VOI aims to provide a novel and interesting experience for both passenger and driver.
