Telescopic current collector for delivering power to electric vehicle from overhead transmission line. A telescopically extendable and retractable mast includes plurality of hollow mast sections with collector head coupled to top mast section. Pneumatic assembly selectively regulates air pressure in mast sections. Winch assembly includes rotatable winch drum and winch cable wound around winch drum and coupled to top mast section. In deployment configuration, mast is extended by selectively extending winch cable and selectively increasing pressure in mast sections to propel successive telescopic extension thereof, raising and engaging collector head with contact line of transmission line. In storage configuration, mast is retracted by selectively retracting winch cable and reducing pressure within mast sections, to propel successive telescopic retraction of mast sections, disengaging and pulling down collector head from contact line to enable foldable storage. Cable displacement measurement of winch cable may be used to regulate height of extended mast.
