In Los Angeles, at the Electric Vehicle Symposium, German engineering company Siemens announced that it is conducting pilot projects using trolleytrucks:
"The eHighway concept is the electrification of trucks and select highway lanes via overhead electrified wires similar to how modern day trolleys or streetcars are powered on many city streets."
Trolleybuses and trolleytrucks offer sustainable electric transportation for a bargain. Trolleylines are relatively cheap to build and can be very easily integrated into existing highways and infrastructures. Furthermore, the vehicles do not require large batteries, which means that trolleybuses and trolleytrucks do not have the disadvantages of electric cars. Trolleybuses are still around in many countries, especially in Central and Eastern Europe, but trolleytrucks have become very rare.
Siemens uses hybrid diesel electric freight trucks with built-in technology and software to connect to overhead electrified wires. "The trucks are designed to use both electricity and diesel power and will automatically switch to electric mode when they detect and attach to the overhead lines. Once the truck leaves the lines, it switches back to diesel. As the technology becomes more widely adopted, the company believes every truck equipped with an electric drive system will be able to use the eHighway regardless if it’s a diesel electric, pure battery, fuel cell range extended or CNG combustion engine vehicle."
Previously: "Get wired (again): trolleybusses and trolleytrucks".
