| Summary: | E-Trike is a three-wheeled electric vehicle that is being developed at ITB. Current development focuses on battery technology and design refinements. Currently there are three battery pack prototypes consisting of cylindrical and prismatic cells. The battery pack prototype is still experiencing various problems and has not met the expected performance. The prototype battery pack has overheating problems, poor cable management and substandard protection. This research was conducted to redesign the existing battery pack by considering the general protection system on the battery pack, namely electrical protection, thermal protection, ingress protection, impact, and vibration protection. In the electrical protection section, electrical components such as batteries, BMS, busbars, nickel strips and cables are selected according to standards. Thermal protection is carried out by initiating the idea of air-based active battery pack cooling using a ducting system to circulate outside air which is sucked in through a blower. For ingress protection, rubber seals are added in each hole to prevent dust and liquid from entering the battery pack. It is also recommended to choose an air filter for further cooling system design. In terms of impact protection, an indentation test was carried out using the simulation method to determine the energy absorption capacity of the battery pack enclosure. The modal analysis simulation produces 20 vibration modes which all have nothing in common with the street and electri motor frequency of 0 – 50 Hz. The battery pack is designed using aluminum plate material and the manufacture of the battery pack prototype includes cutting, bending and Welding processes. The estimated cost of making a battery pack prototype is Rp25.890.466,00. |
