Every custom assembly, high-voltage component, and liquid-cooling loop is engineered to conform with ISO 9001 and IATF 16949 standards, mitigating thermal degradation and optimizing current transfer efficiency.
Overcoming the thermal limits and voltage barriers of modern e-mobility energy distribution.
Increasing system voltage from 400V to 800V reduces current flow for the same power delivery, minimizing resistive heat generation in wiring. This requires special insulation materials and highly advanced busbars to maintain safety and compliance.
Integrating wide-bandgap SiC semiconductors in DC/DC power conversion stages limits switching losses, driving efficiency to over 98.5%. This enables smaller profiles in onboard chargers and motor drive units.
High continuous charging currents cause significant heating. Our thermal designs use dedicated coolant plates and high-conductance plates to manage temperatures, keeping battery modules below 45°C during rapid charging.
In modern fast charging topologies, thermal management is key. High currents (exceeding 250A continuous) create significant heat challenges. Under IATF 16949 standards, high-power systems must run below critical limits to prevent thermal degradation and failure. Our specialized aluminum liquid cooling plates integrate direct coolant flow paths to dissipate heat from IGBT modules and power storage compartments.
Our high-voltage wire harnesses feature specialized flame-retardant CPVC and custom tin-plated copper jumpers. These components offer low resistance and high heat endurance, preventing overheating during DC rapid charging. Using premium raw materials and automated processes, we produce systems that remain stable over long operational lives.

Analyzing intent, mitigation strategies, and custom engineering frameworks for Tier-1 automotive and industrial purchasers.
Global companies need tailored designs to fit their specific spaces. Our ODM engineering services cover custom cable lengths, high-voltage connector layouts, and specialized bracket assemblies to match your exact vehicle configurations.
Large scale projects like 5MWh energy storage systems require reliable thermal management and robust power management units. We optimize layouts for steady temperature distribution and reliable electrical performance under full continuous loads.
We maintain structured relationships with raw material suppliers to buffer against market volatility. This helps us ensure steady manufacturing schedules, secure lead times, and predictable pricing for our long-term contracts.
For automotive applications, components must undergo environmental testing (from -40°C to 125°C), high-voltage isolation checks, salt-spray testing for outdoor parts, and vibration profiling. This testing ensures reliable performance over long service lifetimes.
Electric vehicle and battery storage installations are subject to strict regional safety laws. Sourcing from a factory with strong regulatory alignment prevents expensive design changes and delivery delays. DCI Autos designs components to comply with international regulatory frameworks, facilitating smooth local approval processes.
Our components are deployed in diverse environments around the world, from hot and humid conditions in Southeast Asia to cold regions in North America. We tailor insulation materials and thermal structures to deliver reliable performance wherever they are used.
Additionally, our localized sales engineers and distribution partners provide fast troubleshooting, on-site technical support, and component replacement services. This support minimizes system downtime for our industrial clients.

Direct technical answers to help guide engineering and procurement decisions.
For customized wire harnesses, engineering layout and initial sample creation typically take 10 to 15 business days. Once the first sample is approved by the client, validation and manufacturing setup require 3 to 4 weeks. High-volume delivery times depend on material requirements, such as special flame-retardant CPVC or custom tin-plated copper profiles.
Our cooling plates are built from premium 6061-grade aluminum alloys and undergo pressure testing to prevent leaks. The internal channels are designed to optimize coolant distribution across hot spots. This keeps temperatures uniform and prevents battery cells or IGBTs from overheating during high-current charging.
Yes. We offer configuration and engineering support for our motor controllers, including the Curtis 1515-5201 series and our high-torque VCUs. We can adjust firmware parameters, current limits, voltage settings, and interface protocols to match the specific needs of your application, whether it's an electric pallet jack or an EV utility vehicle.
We manage export logistics, custom clearances, and shipping paperwork. Our components are certified to international standards, including CE, UL, and RoHS. We package our high-voltage wiring, controllers, and liquid cooling components in robust, export-grade shipping containers to prevent damage during transit.
Every production batch undergoes comprehensive testing in our quality labs. This includes high-voltage isolation testing to confirm insulation strength, electrical resistance tests, thermal imaging under load simulation, and vibration testing. These quality control steps ensure that all shipped parts are ready to perform reliably in demanding environments.
