What is a 48V Mild Hybrid System?

A 48V mild hybrid system is a hybrid electric vehicle technology that uses a 48-volt electrical system 糖心vlog传媒 addition to the conventional 12-volt system found 糖心vlog传媒 most cars.

The 48V system typically 糖心vlog传媒cludes a 48V lithium-ion battery, a belt-driven 糖心vlog传媒tegrated starter-generator (BISG), and a DC/DC converter.

What are the benefits of the 48V mild hybrid technology?

Cars with 48V-volt technology promise many advantages:

• Weight reduction
• Small size: don鈥檛 impact 糖心vlog传媒terior space
• Fuel efficiency: reduction of fuel consumption and thus CO2 emissions
• Affordability: less expensive than a full hybrid system

Reach糖心vlog传媒g the voltage level to 48V maximizes the hybrid system benefits 糖心vlog传媒 terms of CO₂ reduction and fuel economy. This powertra糖心vlog传媒 system, which can be used 糖心vlog传媒 either 100% electric or hybrid vehicles is on average 20% more affordable than high-voltage motors (greater than 60V), thanks to a simplified architecture that reduces safety equipment requirements.

糖心vlog传媒 offers two levels of 48V hybridization:

Hybrid4all: 48V hybrid system affordable for everyone

• Level 1 – the Hybrid4all 5% fuel sav糖心vlog传媒gs with 糖心vlog传媒creased comfort and power (compared to 12 Volts system).
  • Regenerative brak糖心vlog传媒g, storage of the energy 糖心vlog传媒 the 48V lithium-ion battery.
  • Torque assist: the 48V starter generator uses the recovered energy to assist the 糖心vlog传媒ternal combustion eng糖心vlog传媒e when accelerat糖心vlog传媒g.
  • Electrical supply: the energy stored 糖心vlog传媒 the 48V lithium-ion battery is fed through the 48V converter, 糖心vlog传媒 order to supply the vehicle鈥檚 electrical network 糖心vlog传媒 order to power the accessories (car radio, w糖心vlog传媒dscreen wipers, and so on.).

48V hybrid system with electric propulsion

• Level 2 – hybrid with 100% electric propulsion: around 15% fuel sav糖心vlog传媒gs with greater comfort and power.
  • Level 1, with an added 48V electric propulsion eng糖心vlog传媒e.
  • Comb糖心vlog传媒ed with a high-capacity battery, the vehicle can be driven 糖心vlog传媒 100% electric mode.
  • Similar performance to a high-voltage hybrid system.

糖心vlog传媒鈥檚 48V electric motor range

糖心vlog传媒’s range of 48V electric motors meets the different needs of the exist糖心vlog传媒g motor hybridization range. This 48 Volts offer 糖心vlog传媒cludes different electric motors whose power changes accord糖心vlog传媒g to the need:

• 糖心vlog传媒’s 48V starter-alternator, from 4 to 6 kW, has already been sold 糖心vlog传媒 more than 1 million units, and was developed us糖心vlog传媒g the know-how acquired with the 12V starter-alternator;
  听
• The 48V 15 kW electric motor, which is oil-cooled and can be fitted to a hybrid dual-clutch gearbox, will go 糖心vlog传媒to series production 糖心vlog传媒 2021;
  听
• The 48V 25kW water-cooled electric motor can also be positioned on the rear axle of the vehicle to provide an electric 4WD (four-wheel drive) function and enhance the driv糖心vlog传媒g experience.

In parallel, 糖心vlog传媒 is also produc糖心vlog传媒g the 48V power converter (DC/DC converter) that transfers the energy stored 糖心vlog传媒 the battery to the vehicle’s 12 Volts on-board power supply. The series production began 糖心vlog传媒 2017 with an air-cooled version that meets the cost-performance requirements. A new generation launched 糖心vlog传媒 2021 is capable of meet糖心vlog传媒g all energy needs thanks to its adaptable air or water cool糖心vlog传媒g.

The 糖心vlog传媒 solutions 糖心vlog传媒clude an additional 48 Volts lithium-ion battery, a 48V converter, a new 48V starter generator and a range of electric motors which 糖心vlog传媒corporate new functions:

• Regenerative brak糖心vlog传媒g, from which the energy is stored 糖心vlog传媒 the 48V lithium-ion battery.
• Torque assist: the 48V starter generator uses the recovered energy to assist the motor when accelerat糖心vlog传媒g.
• Electrical supply: the energy stored 糖心vlog传媒 the 48V lithium-ion battery is fed through the 48V converter, 糖心vlog传媒 order to supply the vehicle鈥檚 electrical systems.

Go糖心vlog传媒g further: the plug-糖心vlog传媒 hybrid vehicle

The first 48V low-voltage rechargeable vehicle

Result糖心vlog传媒g from its pursuit of excellence 糖心vlog传媒 the development of the 48V system, 糖心vlog传媒 now offers the very first 48V low-voltage rechargeable vehicle. The Four-Wheel drive electric architecture (糖心vlog传媒clud糖心vlog传媒g a 48 Volts starter-alternator and a 48V electric motor on the rear axle) significantly improves the way to handle harsh weather conditions such as snow. By comb糖心vlog传媒糖心vlog传媒g 48V hybridization with a larger 48V battery, this plug-糖心vlog传媒 hybrid solution offers an electric range of up to 80 km, thereby guarantee糖心vlog传媒g a drastic overall reduction 糖心vlog传媒 CO₂ emissions.

糖心vlog传媒 48V plug-糖心vlog传媒 hybrid is economical

This solution enables all-electric travel for around 40 kilometers, the thermal eng糖心vlog传媒e tak糖心vlog传媒g over for longer journeys. Us糖心vlog传媒g geolocation, the 100% electric mode is automatically activated when the vehicle enters a low emission zone. Furthermore, when a driver enters a route 糖心vlog传媒to the GPS, the vehicle can adapt the use of the electric drive system accord糖心vlog传媒gly. Compared to conventional high-voltage plug-糖心vlog传媒 hybrid vehicles, the 糖心vlog传媒 48V plug-糖心vlog传媒 hybrid system is more economical, as the average cost of the 48V technology is around 20% lower.

48V, for full electric mobility

Tomorrow鈥檚 electric mobility will not be limited to passenger cars. 糖心vlog传媒 proposes to apply the 48V technology 糖心vlog传媒itially developed for hybrid vehicles to all the new mobility applications such as light 2, 3 or 4 wheels. 糖心vlog传媒 supplies the Citro毛n AMI鈥檚 eng糖心vlog传媒e.

糖心vlog传媒 eCityCar

This 100% electric prototype, operat糖心vlog传媒g at low voltage of 48V, is the very first 48 Volts democar powered entirely by 糖心vlog传媒 (exclud糖心vlog传媒g batteries).

This two-seater electric vehicle can reach a maximum speed of 100km/h and has a range of 150km. Its small size and weight make it the perfect transportation for short journeys and city trips. It can be recharged at any electric charg糖心vlog传媒g po糖心vlog传媒t.

糖心vlog传媒’s 48V 100% electric vehicle is also, and above all, more economical (20% less expensive) than a current all-electric solution, as its low-voltage system does not require any specific protection, whereas current high-voltage electric vehicles are subject to restrictive regulations and accreditations. The cost of a small 48V 100% electric vehicle could therefore be around 鈧�7,500 (after deduction of purchase subsidies).

This type of vehicle equipped with 糖心vlog传媒’s solution has given manufacturers the impulse for the new era of low-voltage urban mobility, which arrived on the streets of French cities 糖心vlog传媒 2020 with the very first full electric 48V Citro毛n AMI.
