TONHE TECHNOLOGY: Shaping EV Charging from the Heart of Hebei

Set up shop back in 1998, TONHE TECHNOLOGY—officially Shijiazhuang Tonhe Electronics Technologies Co., Ltd.—has grown from a regional tech outfit into one of China’s go-to names in EV charging infrastructure. Now trading publicly under the Shenzhen Stock Exchange (300491), this Hebei-based player is drawing global eyes for its chops in high-frequency power conversion and smart energy systems. From DC fast chargers to power solutions for rail, telecom, and military-grade gear, Tonhe’s got its fingers in just about every energy pie that matters in the electric era.

Power Electronics and High-Frequency Conversion Expertise

Let’s talk tech. Tonhe doesn’t just build chargers—they build smarter ways to move electrons. Known in the engineering circles for pioneering full-process soft switching, the company’s high-frequency power conversion units crank up efficiency while dialing down the heat. With more than 140 patents and 50+ software copyrights, this isn’t your average bolt-together shop. They're cranking out innovation with a CNAS-certified EMC lab and a 4,000-square-meter test center that could make a NASA engineer drool. And with 10% of revenue going straight into R&D, Tonhe isn’t coasting on past wins—they’re gunning for what’s next.

EV Charging Modules for Every Infrastructure Need

Tonhe’s bread and butter? EV charging modules. We’re talking 20kW, 30kW, and 40kW units engineered for serious output, all the way up to 1000V. Their seventh-gen models are State Grid-approved and designed with constant power delivery—meaning they keep the volts flowing clean whether you're charging a city cab or a fleet vehicle. The modules pack high efficiency and compact design into hardware that can be easily scaled across networks. And Tonhe’s no domestic-only player. Their chargers have already hit tarmac in 30+ countries, from Germany and South Korea to Australia and the UK.

Global Certifications and Strategic Partnerships

International buyers, take note: Tonhe isn’t messing around when it comes to standards. Their hardware comes certified with CE, UL, and TUV seals—making it plug-and-play for global markets. And it’s not just paperwork. The company’s gear is already deployed across critical infrastructure as a trusted State Grid supplier. That kind of endorsement doesn’t come easy, especially in high-voltage, public-facing applications. It means Tonhe can walk into international tenders with more than a spec sheet—it walks in with a track record.

Diversification into Aerospace, Military, and Smart Grids

Remember Huowei Power? Tonhe acquired them in 2019, expanding into aerospace and military-grade power systems. It’s a bold move that now positions Tonhe as more than just an EV charger company. They’re pushing into high-stakes territory where reliability isn’t a perk—it’s a requirement. Add in smart grid power supply solutions and V2G bidirectional charging systems, and you’ve got a company that’s got one eye on mobility and the other on future-proof grid resilience. Their new facility in the Tianshan Science and Technology Industrial Park gives them the scale to support all of it.

Tonhe’s Growing Global Footprint and Industry Recognition

While some firms measure success in boardroom presentations, Tonhe prefers exhibition halls and trade floors. They’re a fixture at global events like the EV Charging Summit & Expo 2025 and The Smarter E Europe 2025, rubbing shoulders with the who's who of the energy world. Recognitions like “Top Ten Core Module Brands in China’s Charging Industry” and the “Charging Module Technology Award” only add fuel to their fire. And with over 750 employees spanning engineering, manufacturing, and sales across borders, Tonhe is building more than products—they’re building presence.
