Maintaining a power reserve from a battery supply has been tackled from a number of areas. You can isolate part of the load via a power-lockout system, you can switch to a second battery bank. Both have there problems, with power-lockout you loss the use of equipment, when switching banks you get spikes, or even power loss. Our approach has been to treat the battery as one bank, but the critical equipment is supplied from one section, the non critical equipment from another. The two section being linked via a power relay, thus if a low battery is detached, relay opens to isolate the two banks. This has the effect of minimising any spikes, and maintained power continuity for all equipment. Critical equipment being supplied from it’s own reserve bank, while full equipment usage is maintained from the remaining service bank for a limited period. Battery bank continuity is automatically restored once a satisfactory service battery voltage is restored.

A second use for the reserve power system is that on engine starting, the relay can automatically drop out, isolating the critical equipment from starter motor low voltages and spikes.

It is intended to offer this system with an integral remote battery isolator relay in a single package. This allows a remote, or high level reserve battery bank to be installed, with localised drop-out and isolator relay package.
