BYD eBus B12

Outstanding performance

Unrivalled performance

  • Up to 600 km range with one charge
  • Up to 105 passengers
  • Up to 500 kWh battery capacity

Designed with passenger comfort in mind, the B12 electric bus boasts an impressive capacity, accommodating up to 105 passengers when fully loaded. The spacious interior provides ample seating arrangements while still prioritising passenger comfort during transit.

With up to 600 km range, the all-new B12 is an ideal choice for high-demand routes, ensuring efficient transportation and passenger satisfaction.

Maximum safety, all included

The BYD B12 incorporates as standard equipment the following safety elements and certifications:

  • Advanced Emergency Braking System (AEBS)
  • Driver Drowsiness and Attention Warning (DDAW)
  • Blind Spot Monitoring (BSM)
  • Lane Departure Warning System (LDWS)
  • Headway Monitoring & Warning (HMW)
  • Pedestrian & Cyclist Collision Warning (PCW)
  • Traffic Sign Recognition (TSR)
  • Speed Limit Indicator (SLI)
  • Intelligent Speed Assistance (ISA)
  • Alcolock
  • R29 - Driver protection certification
  • R93 - Front underrun protection
  • R155/R156 - Cyber security certification

Blade Battery in Chassis

The BYD B12 revolutionary battery integration inside the chassis has multiple advantages. The batteries ingeniously form part of the structure of the vehicle,increasing torsional stiffness to an impressive 55,000+N.m/° while reducing the vehicle centre of gravity by 40% and at the same time increasing the vehicle tilt angle by 47%, enhancing stability and maneuverability. The overall bus weight is also reduced by 10% thus increasing the range and reducing the energy consumption.

6-in-1 Integrated Controller with Silicon Carbide technology

The B12 incorporates the unique BYD 6-in-1 controller which allows for quick and convenient 'on the road' changeover and reduces downtime.
In addition, the 6-in-1 BYD controller usescutting-edge Silicon Carbide (SiC) technology. The SiC modules yield an impressive 99.5% efficiency with a 15% weight reduction compared to traditional controllers.

Wheel Hub Hairpin Motor

This innovative bus is equipped with two 150kW wheel hub hairpin motors for maximum energy efficiency.
This advanced technology combines flat wire and an oil-free solution, resulting in a 15% weight reduction.
The motor operates at an impressive 95.5% efficiency with very low motor noise levels. It offers a power boost of up to 600 N·m torque, providing responsive acceleration, especially beneficial on steep inclines and for quick starts, delivering a dynamic driving experience and enhanced overall performance.
By pushing the boundaries of motor design, the B12 ensures optimal power delivery and a quieter, more comfortable ride.

Integrated Thermal Management System

The B12 features an Integrated Thermal Management System incorporating various components for optimal energy utilisation.

This system comprises integrated drive cooling, battery cooling, battery heat pump heating, and drive waste heat recovery.

By effectively managing thermal energy, the B12 battery heating speed increases by 30%~80% and energy consumption is reduced by 10%~50%, contributing to extended range and reduced operating costs.

BYD Active Suspension Control System

Incorporating the Active Suspension Control System, the B12 sets a new standard for ride quality. The electronically controlled CDC shock absorbers provide lower damping, resulting in improved driving comfort.

The suspension can be adjusted in real-time based on the vehicle’s motion status, allowing the driver to better control the vehicle and enhancing both safety and passenger satisfaction.

Flexible and powerful charging solutions

The B12 electric bus provides flexible and diverse charging options with various charging port positions (front, rear, left, right, and top).

The charging power options are also impressive, with a single gun capable of 200 kW, and a maximum charging power of 500 kW with the use of pantograph.

This means that B12 can conveniently be charged in the shortest time from 0% to 100% in just one hour, minimising downtime and maximising productivity for bus operators.
