Part of the EV Charger Procurement Guide<\/a><\/p>\n

EV Charger<\/a> RMA Cost<\/strong> Breakdown\uff1a Chargers offered at discounts of up to 50 euros per piece have a catch. If the device later breaks, there is a risk of financial loss of over 1200 euros. When determining the actual total cost of a charger, you should not only look at the unit price ex-factory. Carefully consider all hidden costs, such as round-trip shipping, repair costs, costs for on-site electricians and even the complete loss of customers and future orders. Smart buyers should not be fooled by price traps in their purchasing decisions. Instead, pay close attention to the efficiency of RMA processing<\/strong> (returns and exchanges), the speed of customer service and most importantly, the actual failure rate.<\/p>\n\n\n\n

What each section tells you<\/strong> about RMA costs<\/strong><\/h1>\n\n\n\n
    \n
  1. What happens if your charger breaks? An average RMA costs<\/strong> around \u20ac 1200 This is 20 to 30 times what you save by buying cheap spare parts <\/li>\n\n\n\n
  2. Six cost points do not appear on the invoice: repair costs, downtime for the customer (\u20ac 150 to \u20ac 400 per case) and cheap, easily defective parts (contactors, surge protectors, communication boards, power modules) With 500 devices purchased and an annual failure rate of 10 %, the RMA cost<\/strong> alone amounts to over \u20ac 60, 000 <\/li>\n\n\n\n
  3. Ask five questions before choosing a supplier: failure rate, RMA procedure, on-site labor costs, on-site spare parts warranty and on-site spare parts availability Avoid suppliers who can withhold parts manufacturers or fail to provide data from on-site procurement <\/li>\n\n\n\n
  4. The actual cost calculation looks like this: Total Cost of Ownership (TCO) = (Price x Quantity) + (Failure Rate x RMA Cost x Quantity) + Customer Losses + Reputational Damage Paying more per unit for a high-quality product will save you thousands of dollars in the long run <\/li>\n\n\n\n
  5. Frequently asked questions: High-quality chargers have an annual failure rate of less than 5 % The warranty period is usually 3-5 years OCPP supports you with remote maintenance repairs, thus reducing unnecessary on-site visits<\/li>\n<\/ol>\n\n\n\n

    What Actually Happens When an AC Charger Fails<\/h2>\n\n\n\n

    Let’s look at a concrete example of a charger failure A 22kW charger<\/a> is installed in a German commercial establishment Eight months after Installation the contactor fails-a common weak point in cheap products The charger no longer works You get a call from the operations manager<\/p>\n\n\n\n

    First you spend 45 minutes on the phone to determine the cause The employee’s working time costs you about 85 euros Then you learn that photos, serial numbers and Installation documents are needed to get an RMA number from the manufacturer This means another 1 hour of paperwork <\/p>\n\n\n\n

    Then you send an electrician on the first visit he checks the device, on the second he builds the replacement parts The two visits cost 180 euros each, so a total of 360 euros Additionally you order a replacement device from the manufacturer Shipping, Customs and fees cost 120 euros Returning the defective device costs 90 euros Processing warranty claims is lengthy By now you have already paid for the new device: 480 euros in total, the cost of a single failure is around 1230 euros The potential loss of revenue for Website operators and the risk that they will never work with us again are not yet taken into account in the calculations<\/p>\n\n\n\n
