42 follows a disciplined process. At the product architecture phase, engineers apply lessons from predecessor designs to guide material selection and printed circuit board assembly layout, ensuring operating conditions include built-in safety margins. The team uses failure mode and effects analysis to systematically identify potential risks, apply cross-functional input and develop a roadmap for rigorous validation. The validation cycle follows a threephase structure familiar to automotive and aerospace engineers. Engineering validation testing focuses on initial validation of design choices and early failure discovery. Then, design validation testing takes designs nearing production and tests them for durability. Finally, production validation testing confirms that mass-production units meet long-term field expectations. The process is iterative. When failures occur, they trigger immediate root cause analysis, corrective actions and revalidation. Through this continuous feedback loop, ChargePoint aims to ensure that products maintain reliability into deployment. AI-driven quality control ChargePoint has also embraced AI to maintain quality oversight across its contract manufacturing operations. The company deployed the Instrumental’s Manufacturing AI platform across its assembly operations. The results, according to a ChargePoint case study, have been significant. Using AI and traceable data records, the company identified and addressed 17 anomalies during the development phase, preventing potential defects from making it into the final design. The platform provided data traceability and analysis that halved the time needed to identify and solve problems. This AI-driven approach to quality control represents a pragmatic adaptation to the asset-light model – one that relies on data transparency and automated anomaly detection. Pros and cons ChargePoint’s asset-light model enables it to scale production without the capital burden of building and operating factories. It can switch or add manufacturing partners as market conditions change. Additionally, it can focus its engineering resources on software, network reliability and user experience – areas where traditional hardware manufacturers may struggle. However, there are trade-offs. Quality control is indirect, mediated through contract manufacturing relationships. Supply chain transparency is less than what ABB or Kempower achieve with owned factories. Moreover, regulatory compliance (notably NEVI ‘Buy America’ requirements) may be more challenging to demonstrate without a wholly owned US manufacturing presence. Whether this model can scale to meet the demands of NEVI-funded infrastructure projects – where uptime requirements are high and failure penalties are real – remains an open question. But ChargePoint’s explicit bet is that software-defined quality management can match or exceed the consistency of traditional automated factories. Capital intensity versus manufacturing control The four companies considered occupy distinct positions on the spectrum between capital investment and operational control. ABB represents the traditional industrial model: spend heavily on automation, own the entire production process and achieve consistency at scale. The trade-off is reduced flexibility because retooling a line that produces one charger every 20 minutes is costly. Tesla follows a similar capital-intensive path but with an important difference in that the factory is subordinated to the ecosystem, and its production metrics are less important than the reliability of its network. The trade-off is outsiders have limited visibility into its manufacturing processes. Kempower offers a middle path. Its modular architecture reduces the need for retooling when power requirements change, and local sourcing provides supply chain visibility without the capital burden of large-scale automation. The trade-off is geographic concentration – Finland is a stable manufacturing base, but scaling globally requires replicating the local-supplier model in each new region. ChargePoint has made the most radical choice: minimal capital intensity, indirect control, but high flexibility to switch manufacturing partners. The trade-off is that quality assurance must be accomplished through process rigour and AI-driven oversight. QA approaches Each company has developed a distinct quality philosophy rooted in its manufacturing model. ABB’s quality advantage is predictability. With intensive monitoring of each DC charger and 15 test facilities simulating more than 400 sessions daily, the company has reduced July/August 2026 | E-Mobility Engineering Modular chargers based on standardised power blocks enable Kempower to scale charging systems with the same technology to meet the needs of EVs from small to large (Image: Kempower)
