BYD has over 25 years of experience designing and manufacturing advanced battery systems, and today has grown to become of the largest manufacturers of safe and reliable commercial and industrial battery systems in the world.

Unmatched Battery

battery technology

BYD Iron Phosphate Battery Systems are designed and manufactured to provide safe, consistent and reliable energy in the most demanding applications. BYD’s Iron Phosphate chemistry was originally designed for utility-scale energy systems that require up to 30 years of service. This extremely stable and reliable battery chemistry is capable of cycling thousands of times with minimal degradation, making it ideal for powering battery-electric buses.

Rigorous Safety
Altoona Testing

BYD Iron Phosphate Batteries must pass a rigorous safety testing program that includes tests such as crushing, puncture, impact, vibration, thermal shock, water submersion, corrosion, short circuit, and more. BYD batteries are designed to remain stable under the most extreme conditions including destructive testing. With BYD’s proprietary Iron Phosphate Battery Technology, you can be confident that your buses are powered by the safest, longest lasting and highest reliability battery systems in the world.

For BYD buses operators, safety is paramount. This is why BYD is focused on designing its buses to exceed federal safety requirements.

Safety Battery


  • Environmentally friendly: No heavy metals or toxic chemicals.
  • Long life: After 10,000 cycles, the battery retains 70% of its original capacity, which enables us to provide a 12-year warranty—the longest in the industry.
  • Safe: Tested in the most extreme conditions
  • Excellent performance in extreme temperatures: Reliable operation from – 40° F to 140° F.

Safest Battery.

BYD’s lithium iron phosphate batteries are the industry’s safest, longest-lasting and most versatile power source. Founded as a battery company in 1995, BYD is now one of the world’s largest battery manufacturers.


Samples from each batch must pass rigorous impact, drop, vibration and external fire testing befor being released for electrifc vehicle integration.


BYD batteries have been road-proven in over 800,000 passenger cars and over 50,000 electric buses across the world.


A 10-year track record and millions of on-road miles means BYD batteries are built to last.


The BYD Powertrain system provides optimal bus performance and maximum efficiency. Each component is thoughtfully amalgamated in a vertically integrated design approach to yield one synergetic system including the motor, controllers, and batteries – all of which are developed, designed, and manufactured by BYD.

Reliable & Efficient

Efficient Drivetrain

The BYD Electric Bus powertrain system is paired with BYD’s signature Lithium Iron Phosphate Battery packs, which are among the safest and longest lasting in the industry. The powertrain system is also integrated with BYD’s “Multi-in-One” High Voltage Controller to minimize power consumption relative to actual wheel output, and ultimately reduce overall bus operating costs. Due to our years of experience, integrated electric powertrain systems are a BYD core competency, with thousands of electric buses successfully operating globally each day in transit and shuttle service.

Advanced Drivetrain Technology

BYD’s racecar-inspired, twin electric, electronically controlled traction motors are located directly in the wheel hubs on each side of the rear drive axle, along with angle-cut, planetary gear sets. This combination of design factors removes the need for combustion, an engine compartment, a driveshaft, or a transmission—providing safer, lower-maintenance, higher-efficiency, continuous smooth motion. With all major components manufactured by BYD, this system is configured compactly for efficiency, space and weight benefits.
