Smart 24 V Battery Switch for a Reliable Redundant Power Supply in Commercial, Construction, and Agriculture Vehicles (CAV)

For highly automated driving, commercial vehicles require an Electric/Electronic (E/E) architecture, which - in addition to sensor fusion - ensures safety-critical processes such as steering and braking at all times. Among other things, a redundant 24 V supply with corresponding disconnection is required. The battery switch is a key component. Commercial, construction, and agricultural vehicles (CAV) need to operate at the highest possible availability and the lowest possible cost of ownership. This is why automated and autonomous driving has the potential to revolutionize the CAV sector. Driverless machines can be operated around the clock and almost non-stop. Platooning allows automated, interconnected trucks to drive in a convoy and very close to each other. Platooning saves fuel. The North American Council for Freight Efficiency has calculated the following: A key function of the system is the battery disconnect switch. This master cutoff introduces an isolator to ensure the batteries in the 24 V main network are properly separated from the redundant 24 V network. For guaranteed reliability in areas with extreme weather, from excessive cold to sweltering heat, a battery disconnect switch design must withstand and work reliably in a range of harsh conditions and environments.
