The move was first reported by the local media outlet Jipian Lab. It reported that Xpeng will introduce Eve Energy as a second battery supplier for its Mona lineup, reducing dependence on BYD, which currently provides all batteries for the series. According to industry sources, base versions of future Mona models will be equipped with Eve Energy prismatic cells, while long-range variants will continue to use BYD blade batteries.
The Mona lineup currently consists of the M03 electric sedan, launched in China in August 2024 with a starting price of RMB 119,800 (about €14,000). It is the first EV jointly developed by Xpeng and Chinese ride-hailing service provider Didi. There are three variants available, designated 515, 620 and 580 Max. The number refers to the maximum range. The entry version has a 140 kW motor and can accelerate from 0 to 100 kph in 7.8 seconds. Both larger variants use a 160 kW electric motor and can accelerate to 100 kph from a standstill in 7.4 seconds.
According to CnEVPost, the Mona M03 remains Xpeng’s highest-volume model. Deliveries reached 15,334 units in August 2025, marking the twelfth consecutive month above 10,000 units. The sedan accounted for 40.66 per cent of Xpeng’s total monthly deliveries. Currently, all variants feature BYD’s blade battery.
Spy images published last week indicate that Xpeng is preparing a second Mona model, an SUV featuring design elements from the M03. Combined with the new dual-supplier battery strategy, the expansion of the lineup is expected to support volume growth in the competitive Chinese EV market.
The integration of multiple suppliers is expected to enhance cost control and supply security. Xpeng already relies on CALB, Eve Energy and BYD across its wider model portfolio. CALB provides the majority of batteries for the G6, G7, G9 and X9, while Eve Energy supplies the P7+ and the 2024 X9. BYD currently holds an exclusive role in powering the Mona M03. Eve Energy will also supply batteries for the extended-range version of the G7, as indicated in regulatory filings.
The supplier ranked fifth in China in July with 12.21 GWh of installed capacity, according to the China Automotive Battery Innovation Alliance (CABIA). BYD ranked second with 70.37 GWh, while CALB topped the list with 128.6 GWh installed.
