The accumulator must not have a voltage greater than 600V, but does not have a capacity limit. An energy meter is installed at competition ensuring no more than 80kW are drawn. Most teams elect to use lithium-ion cells, but both lead acid cells as well as other energy storage devices such as capacitors are also permitted — this accounts for the commonly referred ''battery pack'' being referred to as an ''accumulator'' in this competition. Cell voltages and temperatures must be monitored and individual cell connected via fusible links. These challenges lead many (especially young) teams to use preconfigured cell modules that are connected together in the accumulator enclosure. The competition organizers attempt to prepare teams for competition EV technical inspection by having teams complete an Electrical Safety Form (ESF) prior to competition — this form outlines many of the parts used in the high voltage system as well as design decisions the team is making.
