An AI sales agent's EV charging station order, checked before it goes out

An AI sales agent prepares an order for Eve Single Pro-line charging stations from the public datasheets: single-phase or three-phase, socket, socket with shutters or fixed cable, the article number, the power setting and current, load balancing and how many stations share a network. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of those datasheets and returns a verdict, every reason and the figures it computed.

Scope: Eve Single Pro-line charging stations: phases, connector, article number, power setting, current, load balancing with a smart meter and stations per network. See everything this validator covers

This validator models orders for the Eve Single Pro-line as set out in the public Alfen datasheets and product pages, not just the scenarios shown below.

  • Variants and article numbers — six Pro-line variants: single-phase or three-phase, each with a Type 2 socket, a Type 2 socket with shutters or a fixed cable (article numbers 904460003, 904460005, 904460007, 904460023, 904460025 and 904460027). The article number the agent states must match the phases and connector it ordered.
  • Power and current — a maximum design power of 7.4 kW single-phase and 22 kW three-phase, and a maximum of 32 A per phase; a power setting below the 3.7 kW start of the listed charging capacity goes to a person.
  • Networks — up to 100 single-socket stations per network, and active load balancing is described as enabled in combination with a connection to a smart meter.

Any order for this charging station that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Alfen publishes none for this product, so this validator produces no price build-up or line-item quote), the S-line and the Double models, the Pro-line DE, accessories and installation, grid connection design and local code. Assumptions: every station in the order is a single-socket Eve Single and counts toward the network limit of 100; load balancing without a smart meter is treated as an error.

The AI sales agentBuilds the charging station order from the conversation and says it is ready.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
An article number that must match the phases and connectorOnly with workarounds
The article number is a free field that has to be compared with a lookup of the chosen phases and connector.		The stated article number is part of the request and is compared with the derived one on every call.
A power limit that depends on the number of phasesOnly with care
The limit changes with the variant, so each variant needs its own comparison.		The maximum is derived from the phases and compared with the power setting on every call.
Load balancing that needs a smart meterOnly with care
A dependency between two options that a rep can easily leave inconsistent when editing the order.		The two options are in one request and the dependency is checked on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for Eve Single Pro-line charging stations from the public datasheets: single-phase or three-phase, socket, socket with shutters or fixed cable, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of those datasheets and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 24 three-phase Eve Single Pro-line charging stations with a Type 2 socket, each set to 25,000 W and 32 A per phase, with active load balancing. The order states article number 904460027. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The power setting is 25,000 W per station; this variant is listed with a maximum design power of 22,000 W. The order states article number 904460027; the chosen phases and connector are article number 904460023. Active load balancing is described as enabled in combination with a connection to a smart meter, and the order has no smart meter.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for load balancing that needs a smart meter, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the power setting per station to 22,000 W and the smart meter connection to yes.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The order states article number 904460027; the chosen phases and connector are article number 904460023.
    12. 
      
  12. Two findings cleared. Still blocking: stated article number does not match the variant.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the stated article number to 904460023.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Three problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
