E electric cars are now whirring through everyday traffic as a matter of course. At the beginning, the trend was to distinguish the Stromer visually from the rest, but nowadays they are hardly noticeable. Just as unnoticed as it is today, a whole fleet of purely electrically powered Mercedes-Benz LE 306 light vans roamed Munich at the 1972 Olympic Games. A short time later, a large-scale test with a total of 58 vehicles followed.

The electric LE 306 was driven by an externally excited DC shunt motor with an output of 35 to 56 kW. A battery weighing 860 kilograms with a voltage of 144 volts and a capacity of 22 kilowatts supplied the motor with energy. That was enough to allow the light transporter with a ton of payload to travel between 50 and 100 kilometers at speeds of up to 80 km /h.

The' push-through cross-change technology 'enables the battery to be replaced within a few minutes .

Rapid battery replacement

However, the special feature of the LE 306 was not just its drive, but the push-through cross-change technology which made it possible to replace the battery within a few minutes. It was pulled out to the side in a charging station, while a new set was inserted from the other side. The whole process should have taken no longer than a normal refueling stop.

In addition to the replacement technology, it was possible to supply the battery in the vehicle with mains power via a charger. In addition, the motor works as a generator when braking and converts the kinetic energy into electrical energy that is stored in the battery. This principleToday's hybrid and electric vehicles have taken over recuperation.
