Abstract :
In the original the paper was intended to review the whole of the position of the electric battery vehicle as it stands to-day. In the present abstract the descriptive sections dealing with the battery, chassis and charging equipment have been omitted, attention being confined to the more important sections. The paper opens with a reference to the early failure of the electric battery vehicle and to the misconceptions which exist as to its proper duty. The battery is not dealt with in detail, but a table showing the characteristics of the two chief types is included, while the motor is dealt with by a brief reference to the main factors controlling its design. The question of transmission is discussed at length, as is also the subject of control. Under the heading of transmission the special circumstances affecting differential action are noted. As information regarding the methods of charging is not readily accessible, it was decided to devote a section to this subject which is probably of greater interest to the user than that of the battery itself. Space does not permit of any considerations of the financial aspect of the question. For information on this point reference should be made to the papers by Mitchell and Watson * and L. Brookman.¿ in which the matter is discussed at length.
