# www.maruikel.com > Maruikel is a Shenzhen-based manufacturer of commercial and industrial electric vehicle charging systems, offering AC Level 2 chargers, DC fast chargers from 30kW to 360kW+, liquid-cooled high-power units, and V2G-ready stations. The company serves charge point operators, fleet managers, and commercial property owners across Europe, Asia, and the Middle East, with a strong focus on OCPP compliance, modular design, and smart load management. Maruikel provides end-to-end support from site planning and grid assessment to custom branding and maintenance, backed by a library of technical articles and investment analyses. This site targets B2B buyers and engineers, not retail consumers. Product pages are pattern-based (e.g., /products/(.*?).html) and not individually indexed here. Many articles assume familiarity with EV charging standards like OCPP, IEC 61851, and regional grid codes. The blog and news sections contain in-depth guides on heavy truck charging, PV-storage-charging integration, and revenue models. Certified to CE, UL, and TUV standards. ## Charging Products - [All Products](https://www.maruikel.com/product.html): Comprehensive catalog of Maruikel's EV charging hardware, including AC home chargers, commercial DC fast chargers (30kW-360kW+), dual-port stations, liquid-cooled cables, and split-type power units for fleets and public networks. -
