Technical FAQs 4

What is a high voltage battery?

The High Voltage system associated with a group of cells strung together in series and/or parallel. The electrical design of the battery pack is associated with fundamental electrical elements.

What is the electrical design of a battery pack?

The electrical design of the battery pack is associated with fundamental electrical elements. These elements are: Busbars, Contactors, Fuses, pre-charge resistors, current sensors, HV (High Voltage) and LV (Low Voltage) Connectors, and wiring harnesses. This will cover: For all of these components we need to consider:

Why is a battery management system important?

This translates into making the battery packs lower cost with higher energy densities. Every single watt-hour stored and retrieved from the cells is critical to extend the driving range. The main function of a battery management system (BMS) is to monitor cell voltages, pack voltages and pack current.

What is a busbar & a battery junction box?

Busbars are the main electrical connections between cells, modules and connect all of the HV system to the outlet connector. Normally made from copper or aluminium. Careful consideration needs to be taken: The HV battery junction box brings together the measurement, control and connections of the battery high voltage (HV) system.
