Evangelion Power Sources

Internal Batteries' Overview

Every Evangelion (except for the Mass Production Evangelions and Eva-04) has an internal battery, which functions as an emergency power pack in cases where the Umbilical Cable would be impractical to use, or if it has been disconnected/severed. The batteries have been used several times throughout the series, notably during the two times (once in Episode 03 and again in Episode 25') that an Evangelion's power cable has been severed.

Uses/Benefits

The batteries are mentioned in-show to provide power for five minutes, or one minute at full power. However, it must be noted that the show itself is not consistent in enforcing this rule - for instance, there is no proper reason why the batteries should last five minutes during the battles against Shamshel and the Mass Production Evangelions but little over one minute in the Israfel battle.

With the umbilical cable connected, the Evangelions must connect a new length of cable whenever the cable reaches its maximum length. The battery allows Evangelions a short period during which their mobility is not hampered by the need to stop and change cables.

Battery Packs on the Eva shoulder pylons

Battery supplies can be extended without the umbilical cable, using large disposable batteries located on the Eva's shoulder pylons. These provide an unspecified extra operating time and are used in the battles against Israfel and Matarael.
