History of Battery Electric Vehicles in 1900
Prior to 1900, battery electric vehicles held many speed and distance records, the most famous of which, was the breaking of the 100 km/h (60 mph) speed barrier. It was by Camille Jenatzy on April 29, 1899 in a rocket-shaped vehicle named Jamais Contente (Never Happy) which reached a peak speed of 105.88 km/h (65.79 mph).
During the early 20th Century, battery electric vehicles outsold gasoline powered vehicles and were successfully sold as city cars to upper-class customers. Because of high technological limitations, these cars were limited to a peak speed of about 32 km/h (20 mph). The cars were marketed as "appropriate vehicles for women drivers". Electric vehicles did not need hand-cranking to launch.

The History of Battery Electric Vehicles
Battery exciting Vehicles or BEVs, predated the Internal Combustion Engine (ICE) vehicles. It was between 1832-1839 that Robert Anderson, a Scottish businessman, imaginary the first electric carriage and Professor Sibrandus Stratingh from the Netherlands designed the first small-scale electric car which was built by his assistant Christopher Becker in 1835.
The storage battery better, firstly by Gaston Plant, a French physicist who invented the guide acid cell in 1859 and the first rechargeable battery. Then, in 1881, Camille Faure residential a more efficient and reliable battery which became so successful in the early electric cars. This discovery caused battery electric vehicles to flourish, with France and Great Britain being the first nations to support prevalent development of electric vehicles.

Battery
A battery is a device consisting of one or more electrochemical cells, which store chemical energy and make it accessible in an electrical form. There are many types of electrochemical cells, together with galvanic cells, electrolytic cells, fuel cells, flow cells, and voltaic cells. Formally, an electrical "battery" is an array of similar voltaic cells ("cells") joined in series. However, in many contexts it is universal to call a single cell a battery. A battery's individuality may vary due to many factors including internal chemistry, current drain, and temperature. Generally, battery life can be prolonged by storing the battery in a cool place and using it at an appropriate current.
Although an early form of battery may have been used in ancient times, the development of modern batteries started with the Voltaic pile, invented by the Italian physicist Alessandro Volta in 1800. Since then, batteries have gained recognition as they became portable and useful for many purposes. Unfortunately, the well-known use of batteries has created many environmental concerns, such as toxic metal pollution. Many reclamation companies reprocess batteries to reduce the number of batteries going into landfills. Rechargeable batteries can be charged hundreds of times before draining out; and even after wearing out they can be recycled.
There are two types of batteries disposable and rechargeable both of which convert chemical energy to electrical energy. Disposable batteries can only be used once because they use up their chemicals in an irreversible reaction. Rechargeable batteries can be recharged because the chemical reactions they use are reversible; they are recharged by running a charging current through the battery, but in the opposite direction of the discharge current.

Postal Marking
A postal marking is any kind of marginal note applied to a letter by a postal service. The most frequent types are postmarks and cancellations; almost every letter will have those, less common types include forward addresses, routing annotations, warnings, postage due notices and explanations, such as for smashed or delayed mail. A key part of postal history is the credit of postal markings, their purpose, and period of use.
Service marks give in sequence to the sender, recipient, or another post office. Advice marks notify about forwarding, miss ending, letters received in bad condition, letters received too late for delivery by a certain time, or the reason for a delay in mail delivery. Dead letter offices would use a variety of markings to keep track of their progress in finding the addressee, such as a notation that the letter had been advertise in the local newspaper. The tracking process for register mail may entail many marks and notations.
Shortly after the eruption of the American Civil War, the Northern authorities affirmed the existing postage stamps invalid and issued new types. Letters using the demonetized stamps received a marking "OLD STAMPS NOT RECOGNIZED", an accidentally humorous comment much prized by collectors today.
