Jointly with XCMG, China’s largest construction machinery producer, BYD has launched three different models of batteries, namely: super hybrid, super fast charging, and super integration. All three battery types can operate at temperatures between -40 and 65 °C and at altitudes up to 5,500 meters, while their single pack power amounts to 17.3 kWh, 37.7 kWh, and 97.7 kWh respectively.
Parameters for the super hybrid battery are a 4C charging rate, 120 W⋅h/kg density, single pack power of 17.3 kWh, and a 20-80 % SoC in 10 minutes.
The super-fast charging battery has a charge and discharge current of 400 A. Its energy density is 160 W⋅h/kg, and a single pack is 37.7 kWh. The highest voltage is 1,500 V, and the battery pack has a life cycle of 7,000 charges. Despite being called super-fast charging, the global 2C charging rate is far from super-fast charging. However, according to BYD, a 10-minute charge can provide 1.5 hours of use.
The super integration battery also has 400 A charge and discharge current. The energy volume density is 320 W⋅h/l, while the single pack is 97.7 kWh. It’s claimed to be the first mass-produced CTB construction machinery battery. One important consideration for construction machinery and commercial vehicles is vibration. The super integration battery can withstand 6 times the vibration intensity of the old national standard.
All three battery types can operate at temperatures between -40 and 65 °C and at altitudes up to 5,500 meters.
Currently, only around 3 % of construction machinery is electrified. With the emission pollution of a diesel construction machine equivalent to around 200 cars, electrification of construction machinery can have a big impact on emissions.
