DC/DC converter

The power electronics that step the high-voltage pack down to 12 V or 48 V for the auxiliary systems, replacing the alternator of a combustion car. Boost converters also appear between an 800 V pack and a 400 V charger.

Direct and alternating current

A battery stores and delivers direct current, flowing one way; the grid and most motors use alternating current, which reverses many times a second. An inverter converts one into the other, and every conversion loses a few percent.

Energy management system

The site-level controller of a storage system that decides when to charge and discharge according to prices, grid signals and the battery’s limits, and dispatches those commands to the BMS and inverters.

IEC 62477-1

The general IEC safety standard for power electronic converter systems and equipment rated up to 1 000 V AC or 1 500 V DC. It is the safety basis for many inverters and DC–DC converters that connect batteries to loads and to the grid, and a reference for product standards on bidirectional converters.

Pre-charge circuit

A resistor and small contactor that charge the inverter’s capacitors slowly before the main contactor closes. Without it the inrush into empty capacitors can reach thousands of amperes and weld the main contactor shut.

Stationary storage

Batteries installed in a fixed place — a container at a solar farm, a cabinet in a home — to shift energy in time or support the grid. LFP cells dominate because cost per cycle and safety matter more than mass.
