Schematic diagram of the design principle of the high-voltage box of the energy storage cabinet

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

What are the parameters of a battery energy storage system?

Several important parameters describe the behaviors of battery energy storage systems. Capacity [Ah]: The amount of electric charge the system can deliver to the connected load while maintaining acceptable voltage.

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.

Why is spacing important in high voltage design?

Spacing is more important in high voltage designs because the voltage across your board makes it much easier for an arc to occur between two conductive elements on your PCB. Any arc that does occur poses a significantly higher risk to both the product and your users.

Why is partitioning a high voltage PCB important?

Partitioning a high voltage PCB is important to provide a gradual decrease of voltage across the board. After you’ve isolated the highest voltage regions on the board, you should still lay out the rest of the board in “zones” that let you step the voltage down gradually.

Do PCB design rules apply to high-voltage PCBs?

Not every PCB design has the same rigorous rules on spacing that a high-voltage PCB design needs. In general, if the normal operating voltage of your product meets or exceeds 30 VAC or 60 VDC, then you should be very diligent about spacing rules in your board design.
