Chilye, a Chinese startup that develops high-voltage battery systems for electric vehicles (EVs), has raised around RMB 100 million ($15.7 million) from a group of investors led by Xiaomi, the latest move of the Chinese smartphone maker joining the EV race.

Why it matters: Leading automakers have been embracing high-voltage battery systems, a technology that enables fewer charging times when using fast chargers and a longer driving range with better energy efficiency and lighter car weight, according to Otmar Bitsche, a director at Porscheโ€™s research unit.

Details: Apart from Xiaomi, other investors include private equity firm Yonghua Capital and state-backed Oriza Holdings, according to a Thursday statement (in Chinese).

  • Chilye said that the proceeds from the round will be spent on researching and developing high-voltage car battery systems and ramping up manufacturing for commercial products without revealing further details.
  • Xiaomi will continue to invest in โ€œprominent domestic companiesโ€ in the EV supply chain. The company sees great potential for Chinaโ€™s auto components segment boosted by smart EVs, according to Sun Changxu, a partner at Xiaomiโ€™s industry investment fund (our translation).
  • Headquartered in the eastern city of Suzhou, Chilye said it has secured clients including โ€œmultiple mainstream automakersโ€ and will have the production capacity to equip 3 million EVs with its products annually by mid-2022.

Context: Xiaomi has set a target of mass-producing its first consumer EV model during the first half of 2024 and recently poached a senior executive from state-owned automaker BAIC Motor to lead its EV project.

  • Xpeng Motors is also transitioning to high-voltage technology with the recent debut of its second electric SUV model, the G9, scheduled for delivery starting September. The company claims it will be Chinaโ€™s first mass-produced vehicle model featuring an 800-volt electrical system.
  • Xpeng, backed by Alibaba and Xiaomi, added that an 800V power system and its proprietary superchargers will allow its vehicles to have a 200-kilometer (125-mile) driving range with only five minutes of charging.
