Electrification is becoming increasingly prevalent in many different vehicle classes and types, and powertrain and vehicle component technology is developing enormously. This is particularly true of batteries, which continue to improve in terms of efficiency, size, charging time and capacity.
In order to increase vehicle performance, there is a clear trend toward higher voltages. Passenger cars are already on the market with a system voltage of 800 V. Heavy vehicles tend to exceed 1000 V, and designers are now planning 1200 V or 1500 V systems. Without higher voltages, current would have to be increased to boost motor performance. This would result in system losses and increase the need for additional copper to carry the current, ultimately leading to heavier vehicles.
Every electric and hybrid vehicle uses many high-voltage components that must be tested for function, safety and reliability during development and series production. In addition, automotive standards require extensive tests to qualify the components.
