Requirements for selecting components of energy storage high voltage box

What is a high voltage box?

to DC and feeding it forward to the high voltage battery. Secondly, the high voltage box carries out the high voltage management in the vehicle, and especially the energy distribution from the high voltage bat tery to the consumers plus providing the DC charging function at high power cha ging points with a three digit kW level of c

Do electric energy storage systems need to be tested?

It is recognized that electric energy storage equipment or systems can be a single device providing all required functions or an assembly of components, each having limited functions. Components having limited functions shall be tested for those functions in accordance with this standard.

What is a modular high voltage box?

Modular extensions are conceivable, such as a high voltage DC booster, the charging communication, a high voltage heater, and the battery management system. The modular high voltage box saves space, weight and cost, for instance on the housing and cabling levels.

What are the design requirements for a battery pack?

An important design requirement is the electrical isolation of the HV components of the battery pack. The HV components include the cell, module, or battery pack terminals and any conductive parts attached to them.

What are the standards for HV battery pack design?

Thus, relevant literature is published in terms of norms and standards as well as patents. An important standard for HV battery pack design is the ISO 6469 “Electrically Propelled Road Vehicles—Safety Specifications,” especially ISO 6469-1 (ISO 6469-1, 2009), and ISO 6469-3, which may serve as a starting point for interested readers.

What is considered a maximum system voltage?

This standard includes preferred voltage ratings up to and including 1200 kV maximum system voltage, as defined in the standard. In defining maximum system voltage, voltage transients and temporary overvoltages caused by abnormal system conditions such as faults, load rejection, and the like are excluded.
