The transition to electric mobility implies an increasing need for charging.<\/p>\n\n\n\n

Indeed, the larger the fleet of electric vehicles becomes, the more electricity storage and distribution infrastructure needs to be deployed.<\/p>\n\n\n\n

This is the specialty of the MOB-ENERGY<\/a> group, in the Lyon region, which has been deploying charging station solutions for customers & visitors, for employees or for vehicle fleets for many years now in the territory.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

What are the technical challenges surrounding the deployment of these terminals?<\/h2>\n\n\n\n
\n\n\n\n

Maximize the energy efficiency of the facilities to be able to charge the maximum number of vehicles at the same time, with optimal performance and reliability that withstands all weather conditions.<\/p>\n\n\n\n

But “energy storage and distribution” implies “precise and reliable temperature management<\/strong>,” especially since the devices are often installed outdoors and are subject to large variations in ambient temperature, which can damage the internal components and the efficiency of the entire system (condensation, humidity, excessive ventilation: everything must be optimized to reduce energy consumption).<\/p>\n\n\n\n

And it is naturally EURODIFROID that is supporting the ramp-up of this deployment, on the “cold” brick, with an initial industrial specification with a strong “design-to-cost” orientation.<\/p>\n<\/div>

What is “design-to-cost”?<\/h2>\n\n\n\n

“Design to Cost” (DTC, or Target Cost Design) is a product design methodology that aims to control the development and manufacturing costs of a product from the earliest design phases.<\/p>\n\n\n\n

Costs are built into the product from the earliest conceptual decisions and, by making the right design decisions early on, unnecessary costs can be avoided in later phases of the product lifecycle.<\/p>\n\n\n\n

This approach allows teams to design high-quality devices while respecting predetermined cost targets from the outset. It also avoids costly and late engineering change orders, and brings new products to market more quickly.<\/p>\n\n\n\n

Unlike “target costing”, which aims to achieve a defined cost, DTC takes into account costs throughout the development cycle to avoid unnecessary expenses.<\/p>\n<\/div>

Specifically, regarding these ERI 25\u2026<\/h2>\n\n\n\n

On paper, an ERI 25 water cooler is not a very complex device to design: we are used to dealing with much larger and more complex devices!<\/p>\n\n\n\n

But precisely: the challenge of cost optimization (components, assembly, etc.) becomes all the more pressing when the product is simple and compact.<\/p>\n\n\n\n

During the initial redesign, the chassis, for example, was completely revised: instead of a 2-tier assembly, the entire cooler is now assembled on a single base, which is much more compact and economical.<\/p>\n\n\n\n

Thus, with the same performance as the initial product, our design has enabled a significant reduction in the cost price (of around -20%), going hand in hand with an improvement in production capacity (simplified assembly).<\/p>\n\n\n\n
