Here, a copper bus bar sits in the mould before the thermoplastic polymer is injected (Courtesy of Celanese) Sensing issues. Modern BMSs monitor multiple parameters at the cell, module and pack level, and the need for sensors and associated wiring inevitably has an impact on the main conductors. With busbars for example, voltage sensing leads are now needed to ensure
Busbars play an important role in connecting battery cells in electric vehicle batteries. Thanks to their outstanding advantages, busbars help to enhance the performance, durability and safety of the battery pack. However, to optimize the performance of busbars, careful design and appropriate material selection are required.
For equivalent electrical/thermal performance, however, the cross section of an aluminum busbar will be greater than that of a copper busbar with, for example, a 1 mm copper conductor replacing a 2 mm aluminum conductor. For EV/HEV applications, copper busbars offer excellent solutions where space is tight, while aluminum busbars, enable efficient energy distribution with weight
Busbars are ideal for the high-power applications that are commonplace in EVs. OEMs first started using busbars in EV battery packs as interconnects for battery modules. To support fast charging, busbars have become a vital part of the charging harness. They also make sense wherever high power is required, such as connections to
Busbars transfer power between the battery cells, manage the charging and discharging process, and protect the system from overcurrent, overvoltage, and overheating. Trends in Busbar Technology. In recent years, there have been significant advancements in busbar technology, resulting in improved system efficiency, reliability, and safety. One
Battery system: Busbar connects battery cells together to form a battery pack, helping to distribute power from the battery to other parts of the vehicle. The busbar in the battery system needs to have high electrical conductivity, withstand large currents and ensure safety during the charging/discharging process.
