Accu Oerlikon - battery power

All exposed metal parts of a battery are live and so there is a danger of injury from electric shock and of accidental short circuits. Be carefull with non insulated tools, bracelets and rings. Touch the battery on the plastic surfaces only.

Compact-Power™ cells and monoblocs have very low internal resistance and can deliver large short circuit currents. These currents have been determined with the two current level pulse method according to the International Standard IEC 896-2,1996. Compact Power™ units can withstand their own short circuit current for 1 minute. Battery installations should be protected according the equipment power output and cross-section of the installed cables. The fuse or disconnecting equipment used must be capable to interrupt the current within 10s of the onset of the short circuit condition. Eventual magnetic forces arising from the short circuit current flow have to be considered. Fuse blowing or switch operation shall not causes a possible ignition of electrolysis gases.

The short-circuit current I_SC of Compact-Power™ batteries is determined according to International Standard IEC 896-2. The following formula is used: I_SC=(U₁) (I₂) - (U₂) (I₁) / U₁-U₂ R_I = U₁ - U₂ / I₂ - I₁
