The battery that powers BYD cars, buses, and forklift trucks

Why the BYD Iron-Phosphate Battery?

The BYD Iron-Phosphate Battery has been developed to power its cars, buses and forklift trucks. Utilizing years of experience in battery technology, the BYD Iron-Phosphate Battery is safe, stable, environmentally friendly and ensures a longer lifetime.

Charging Solution

BYD offers multiple charging solutions, such as 7kW and 40kW AC charging for the BYD e6, 80kW charging for the BYD ebus, and 40kW AC charging. The 200kW pantograph is under investigation. The BYD charging infrastructure is easy to install, use and maintain.

AC Power-Interface

The BYD AC on-board charging system is small and light, easy to operate and suitable for various locations. The BYD AC Power-Interface adds a DTU module which monitors the charging process, collects the vehicle charging information, and uploads all information automatically to the service centre.

Vertical Charging Carrousel

The difference for an electric taxi driver is having to change from a refueling to a charging habit, and learning to solve any charging issues. The BYD specially designed Vertical Charging Carousel makes charging an electric taxi very easy and convenient. Moreover, at least 12 units of the BYD e6 can be charged at the same time in only a 42m2 space.


Space Utility

12 electric vehicles can be charged at the same time in a 42 m2 circulating charging area.

User Convenience

Easy to operate for even a new driver, including entering and exiting the carousel.


This Vertical Charging Carrousel is designed with resistance to strong earthquake (8 of Ritcher Scale).


Based on the various sets of the charging machine, multiple combinations can be chosen.

Vehicle to Grid

During the off-peak hours, BYD EV users can expect to charge the vehicle from the grid and store energy in the internal battery. While during peak hours, the user can opt to transmit power from the internal battery back to the grid as an emergency power source, which can help the grid to achieve load shifting and pressure reducing.

Vehicle to Vehicle

This function can help to realize the"inter-charging"between two electric vehicles in an emergency situation in case one vehicle has run out of battery capacity. In the event of power blackout, one EV (internal battery) can be charged via another.

Vehicle to Loads

When the EV user is isolated from the power grid, an electric vehicle can supply A/C power (i.e. single or three-phase) to any electric appliances under 15kW.

A New Level of
BYD Advanced Technology
in New Energy Vehicles .

The wheel-hub motor provides BYD ebus with greater efficiency, as well as saving space.

BYD's self-developed wheel-hub motor is adopted in the BYD ebus. It is installed in the rear drive axle together with regenerative braking technologies. Compared with a normal motor, the rear drive axle system in the BYD ebus has no gear box, no transmission shaft, and no differential mechanism. The power from the motor is directly transmitted to the wheels, so that significant improvements are achieved in transmission efficiency and reductions in noise and vibration. In addition, the bus weight can be cut by 300kg, and interior space is greatly saved.
BYD wheel-hub motor tech specs:
Motor type Permanent magnet synchronous motor
Max. Power 90 KW(*2)
Max. Torque 350N.m(*2)
Rotation speed 0~7500 rpm
Rated operational voltage 540 V
Speed ratio 17.7 (top speed: 70km/h)
Cooling type Water-cooling

Electric or gasoline?

The motor controller with integrated on-board charger controls the function of battery and motor, allowing the driving motor to run in reverse, changing DC (direct current) to AC (alternating current), and regulating the vehicle speed. The distributed Battery Management System consists of the signal collector and controller, which can inspect every cell’s working status.

Regenerative Braking System

The Regenerative Braking System converts part of the kinetic energy into electricity and stores it in the battery to give additional driving range. The vehicle range can be increased accordingly with lower noise by adopting such a regenerative system.

Dual Mode System

  • The BYD Dual Mode (DM) system allows drivers to switch from all-electric mode (EV mode) to plug-in hybrid electric mode (HEV mode).
  • With the DM system the car can be switched to either pure electric or plug-in hybrid, at the preference of the driver. The car in HEV mode is mainly electric powered and the engine only has an assistive function. Given that fact, this hybrid distinguishes itself from other hybrids and can be called a strong hybrid. The DM system is more energy-saving than gasoline only and more powerful than all-electric ones.

The Advantages of DM System

  • Unlimited Range

    When the car runs out of electricity, you can charge it or simply switch to HEV mode to extend your drive.
  • Save Money

    You can choose to always drive the car in all electric mode, with the gasoline as a backup.
  • Charge at Home

    The DM system can be charged directly from a household power outlet.
  • Environmentally Friendly

    There is no tailpipe emission from the car while in EV mode.

New DM system improves efficiency,  power and energy-saving

The DM system was first adopted in the BYD F3DM, which was introduced in 2010. In 2012, the DMII system was launched with the BYD Qin, offering improvements in efficiency, power and energy-saving.
