Bosch develops user-friendly charging cable
Bosch developed a universal charging cable that can be used at a home power socket and a charging station. The typical ‘box’ attached to the slow home charge cable disappears.
EV drivers often complain about carrying two types of charging cables in their car’s (often small) trunks. One is suitable for charging the car via a charging station on the road, and the other is used for slow charging at a regular (home) power socket when, for example, you go on a family visit or weekend trip with the car to a place where there is no public charging point available.
Bosch is currently developing a cable that integrates both systems into a single cable set and eliminates the clumsy control box between the mobile charging cable.
Safety components become more compact
The Bosch charging cable was unveiled at the IAA Mobility in Munich, primarily focused on electric mobility. Bosch listened carefully to EV drivers’ criticism of this complicated procedure of having two cables in the car.
The large control box also disappears, but its function remains unchanged. This unit communicates with the car in the same way as a charging station or a wall box and checks whether there is a proper earth connection. It also monitors the temperature of the components (battery, inverter) before starting the charging process.
If one of the parameters falls outside the limits, the charging process is immediately interrupted. The components that guarantee this safety have been made more compact to fit into the housing of the connecting plugs.
The charging cable is universal and is, in principle, suitable for almost every EV on the market. It also provides a (retrofit) solution for older existing vehicles. Slow charging (mode 2) from a socket can be done at a flow of 2,3 kW (10 A), and faster charging (mode 3) at a (public) charging station can be done up to 22 kW.
Bosch plans to have the new charging cable on the market by mid-2022. However, an exact price is not yet known.
