Taiwan-based Delta Group, the world’s largest provider of switching power supplies and DC brushless fans, as well as a major supplier of power management solutions, components, visual displays, industrial automation, networking products, and renewable energy solutions, is entering the electric powertrain market.
Taiwan-based Delta Electronics has integrated existing automation, motor, servo-motor and electrical electronics technologies to develop its own gasoline-electric series hybrid propulsion system—the first gasoline-electric hybrid propulsion system developed by a Taiwanese electronics company. The design includes battery pack, power inverter, power control unit, traction motor and vehicle control unit.
Delta has installed the system in a test vehicle, which is now undergoing road tests.
As supplies of fossil fuels dry up, the energy crisis makes the development of alternative energy sources the most important issue facing us today. Transportation in particular is relatively energy intensive and produces air pollution. Currently all of the world’s car makers are looking at electric or hybrid propulsion vehicles. As Delta Electronics has always been a leading provider of power management and automation solutions, this gives us an advantage when it comes to the design and manufacturing of electric vehicle propulsion systems.—Delta Vice Chairman and CEO Yancey Hai
The original gasoline engine and transmission system were removed and replaced with a hybrid propulsion system developed by Delta. The engine in the system is not used for propulsion and is only run to charge the 18 kWh lithium-ion battery pack.
Road tests show that depending on the road and traffic conditions, each liter of petrol used by the engine is sufficient to generate enough power for the car to travel 20 to 30 kilometers (3.3 to 5 L/100km or 47 to 71 mpg US). The prototype system as an output of up to 100 kW (134 hp) and 830 N·m (612 lb-ft) of torque. This level of performance is more than adequate to propel a car weighing 1660 kg (3,660 lbs), according to Delta.
Delta Electronics can provide a complete propulsion system solution whether it is a purely electric, tandem or parallel gasoline-electric hybrid propulsion vehicle, said Simon Chang, General Manager of Delta’s Industrial Automation Business Unit. The system includes:
- Battery Management System (BMS)
- Power Control Unit (PCU)
- Integrated Stator & Generator (ISG)
- Traction Motor
- Vehicle Control Unit (VCU)
Delta’s strategy in automobile electronics is based on the pure electric and petrol-electric hybrid vehicles’ propulsion systems described above. The vehicles will then require advanced components such as LED lighting, high-efficiency brushless DC fan cooling systems, electric power steering (EPS), passive keyless entry (PKE) and various types of DC/DC and DC/AC inverters. This naturally includes a Charging Station that no electric vehicle can do without.
Delta Electronics has already accumulated extensive design and manufacturing experience in many automobile electronics components. As we are now a certified supplier for electromagnetic components, cooling management products and stepped motors to the world’s top car makers; this gives us an advantage over the rest of the electronics industry when it comes to the automobile electronics market.—Simon Chang
