EV industry colossus BYD, in collaboration with XCMG, China’s largest producer of construction machinery, has launched a trio of battery models specially designed for construction machinery. The new batteries are expected to debut in vehicles manufactured by XCMG, potentially giving BYD a first-mover foothold in this rapidly growing vehicle segment.

All three battery models—Super-hybrid, Super-fast charging and Super-integration—are variants of BYD’s lithium iron phosphate Blade battery.

The Super-hybrid battery pack features specific energy of 120 wh/kg, energy capacity of 17.3 kWh, and a 4C charging rate.

The Super-fast charging battery offers a charge and discharge current of 400 A, can operate at a voltage up to 1,500 V, and boasts a lifespan of 7,000 charges. Specific energy is 160 Wh/kg, and a single pack is 37.7 kWh. Car News China notes that the 2C charging rate is far from what most would consider “super-fast.” However, according to BYD, a 10-minute charge can provide up to 1.5 hours of use.

The Super-integration battery is designed for cell-to-body integration into vehicles. As construction machinery does tend to vibrate, this pack is designed to withstand up to six times as much vibration intensity as a standard battery pack. This model features charge and discharge current of 400 A, energy density of 320 Wh/l, and capacity of 97.7 kWh.

Car News China notes that, while the battery capacities may seem quite low, several packs can be installed in a single vehicle, depending on requirements.

All three battery types are designed to operate at temperatures between -40 and 65° C and at altitudes up to 5,500 meters.

Mass production of the new packs has reportedly begun, and they are expected to start appearing in  XCMG construction vehicles soon.
