The first electric tricycle

The first electric tricycle in the world was born in 1881. Its inventor was Gustav Truff, a French engineer. It was a tricycle powered by a lead-acid battery. In 1873, the electric tricycle, which was invented by Robert Davidson, an Englishman, powered by a primary battery, was not included in the scope of international confirmation. Later, lead-acid, nickel cadmium, nickel hydrogen batteries, lithium-ion batteries, and fuel cells emerged as electric tricycle.

Other basic requirements for electric vehicles

A main switch shall be used to disconnect at least one electrode in the on-board power supply (such as traction battery). The main switch shall be able to be controlled (on or off) by a manual device accessible to the driver.

An obvious signal device (such as acoustic or optical signal) shall be used to permanently or intermittently show that the driving system is ready for operation.

If the power of the electric vehicle automatically decreases significantly (for example, due to the high temperature of the drive system or power source components), this state shall be displayed through an obvious device.
