isolation of all electrical energy sources is not possible. Even with the wiring disconnected, individual battery cells or packs will be live at their terminals. there may be multiple points of isolation for circuits in the remainder of the electrical installation, particularly if the system is intended to operate off the grid.
With larger capacity energy storage installations, thermal management may prove cost-effective for improving performance and increasing time between maintenance replacements of batteries of certain technologies.
The EESS controller may be connected to sources of energy via a.c. coupling or d.c. coupling. Necessarily, the connection to the grid supply will be via a.c. coupling. Coupling to other energy sources at standard voltages and frequencies defined in BS EN 50160 provides ready compatibility in the ratings of devices.
