1 INTRODUCTION. High-performing lithium-ion (Li-ion) batteries are strongly considered as power sources for electric vehicles (EVs) and hybrid electric vehicles (HEVs), which require rational selection of cell chemistry as well as deliberate design of the module and pack [1– 3].Herein, the term battery assembly refers to cell, module and pack that are
The Parallel Hybrid or Hybrid Electric Vehicle abbreviated HEV. Called the “Self-Charging Hybrid” by Toyota as the battery pack cannot be independently charged from a plug. The mechanical output of the electric motor is connected to the engine (fuel to mechanical). This means that the electric motor can be used to assist the engine and hence the engine can be optimised for fuel

The design solutions are assessed from an assembly, disassembly and modularity point of view to establish what solutions are of interest. Based on the evaluation, an “ideal” battery is developed with focus on the hardware, hence the housing, attachment of modules and wires, thermal system and battery management box.
Focus is on heavy-duty commercial vehicles and high voltage batteries. EV batteries are typically divided in three levels namely pack-, module- and cell level. In this project the study will be limited to focus on pack- and module level. Concentration is on the hardware of a battery pack. Access information due high degree of confidentiality.
After the battery module is assembled, it needs to be placed into the battery tray. As this tray is a key structural component of the vehicle as well as integral in protecting the battery cells, it needs to be of the highest strength and stability.
The BMS and power relays can be found inside the pack whereas the DC-DC converter, HV controller and other HV units are mounted in other parts of the vehicle. Furthermore, the pack consist of ten modules, divided in two rows and two levels with the lower modules containing 30 cells and the upper modules 24.
Batteries in general is also revised to get a better overview of what functions and parts are included in a battery in order to map its functions in an Enhanced Function-Means model. This model creates an image of how the functions and design solutions are connected to each other.
The integrated solution offers flexible wireless freedom and reduces the cost of operator training and, in the end, the risk of energy-consuming rework. As with so many stages in the EV battery assembly process, there is no room for error when assembling the electrical components.
