This clarification shifts core responsibility to the vehicle manufacturer’s system integration, not cell manufacturing. Recently, Volvo announced a mass recall of the EX30 model in the United States, Canada, the United Kingdom, South Africa, and other countries. In the process, Volvo confirmed that 10,440 EX30 vehicles in the UK equipped with 69kWh Sunwoda battery packs may have design defects. Meanwhile, the company advised owners to limit charging to 70%, stating this measure could “significantly reduce” the risk of thermal runaway.EX30 EV battery fire warning. EX30 The incident quickly drew public attention, with multiple media outlets pointing fingers at battery manufacturer Sunwoda. Some reports resurfaced a November 2025 incident where a Volvo EX30 caught fire while parked in Maceió, Brazil, further fueling controversy. Amid mounting pressure, Sunwoda Chairman Wang Wei responded in a recent interview: online rumors are untrue—the battery packs in question were not supplied by Sunwoda but by Volvo’s in-house system factory. He further explained that while the battery cells were indeed produced by Shandong Geely Sunwoda Co., Ltd., a joint venture between Geely and Sunwoda, Sunwoda holds only a 30% stake and does not have controlling power. Sunwoda’s official statement also emphasized that while the recalled EX30 battery packs used cells from Shandong Geely Sunwoda, responsibility for the entire battery system’s integration and supply does not lie with Sunwoda. This clarification shifts core responsibility to the vehicle manufacturer’s system integration stage, rather than the cell manufacturing process. EX30 As the Volvo recall gained attention, a legal dispute between Sunwoda and Geely emerged. Sources close to Sunwoda revealed that the recalled battery packs, BMS (Battery Management System), thermal management, and structural components were all designed and manufactured by Geely’s EV technology subsidiary, Viridi E-Mobility Technology. More dramatically, Sunwoda announced on December 26, 2025, that its subsidiary Sunwoda Power Technology Co., Ltd. was sued by Geely Viridi over cell quality issues, with claims reaching RMB 2.314 billion. Viridi EV Sues Sunwoda. Geely alleges that cells delivered by Sunwoda from 2021 to 2023 had serious quality defects, causing widespread issues such as slow charging and inflated range claims in models like the Zeekr 001 WE86. Geely incurred massive costs from large-scale free battery replacements to protect its brand reputation. The lawsuit is currently pending with no further developments.
