Bosch tests hydrogen vehicles

Even for long distances – In the Transportation professional goodsbut also for people if needed, the goal of getting to their destination and making deliveries as quickly as possible often conflicts with the limited range of electric vehicles and with Long shipping times for them batteries, not counting the effect of the payload carried (and weather conditions) on “full power” mileage. The strengths of electric cars Powered by fuel cells, high autonomy and above all fast refueling times, which are slightly higher than those required by gasoline and diesel, can play a role in addressing and resolving critical issues typical of battery electric vehicles. In fact, with a fuel cell power source, it is theoretically possible to use commercial vehicles as well Long Distanceswithout the time required for intermediate refueling (assuming an equipped point is found!), unduly detrimental to the overall flight duration.

In collaboration with ABT ELINE – The project partner is ABT eLine, who designed and converted vehicles in collaboration with Bosch Engineering. For the record, ABT (known above all in sports and tuning, due to its links with the Volkswagen Group brands) has in the recent past created electric variants of the Volkswagen T6 and Caddy from the previous series, the current one with its own section. Intended for “green” transitions. everybody ‘IAA . Transport In Hanover, the exhibition dedicated to commercial vehicles, scheduled for September 20-25, Bosch will offer visitors the opportunity to test these prototypes on the road.

hydrogen power train – For System A fuel cells The developers were able to use the components almost exclusively bush. The fuel cell assembly which includes the stack, anode power unit with gas hydrogen injector, recirculation blower, electronic control unit, electric air compressor and fuel system components is installed. hydrogen storage, as well as a large number of sensors. The technical basis for both cars is the commercially available electrified trucks. The batteries were replaced by a fuel cell, five tanks totaling over 10 kg of hydrogen and a smaller lithium-ion battery. ABT partner eLine has adapted the cooling system, vehicle control system and electrical system. Bosch designed the fuel cell system, integrated it in the car with the hydrogen storage system and developed the associated control system. After the required technical tests, the vehicles received official approval for use on the road.

up to 540 km – The project already provides important information: even if it is fully loaded, the vehicles can Travel up to 540 km and with rTime to refuel complete with suns 6 minutes. The fuel cell could therefore be an interesting alternative solution for electric propulsion in the future, particularly for fleet operators whose trucks cover particularly long distances during the day and return to storage in the evening.
