Predictika · DC fast-charging site configuration: power unit, power modules and charging satellites

An AI sales agent's DC fast-charging site configuration, checked before it goes out

An AI sales agent prepares a configuration for a DC fast-charging site: a power unit of 50 kW power modules, the charging satellites hanging off it, the cable length, the connectors and the power the site needs at peak. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published data sheet limits and returns a verdict, every reason and the figures it computed.

Scope: Power Unit C501, C502 and C503 with Satellite V2 charging outputs: power modules, number of outputs, site demand, cable length, CHAdeMO and CCS2 current. See everything this validator covers

This validator models site configurations built from one product line, the Kempower Power Unit (C501, C502, C503) with Satellite V2 charging outputs, not just the scenarios shown below.

  • Power modules — each module is 50 kW; a single-cabinet C501 takes up to 4 modules (200 kW), a double-cabinet C502 up to 8 (400 kW) and a triple-cabinet C503 up to 12 (600 kW). The power stated on the quote is compared with the installed power, and the site demand at peak must fit within it.
  • Charging outputs — one power unit supports up to 8 charging outputs (a single satellite has one, a dual satellite two), or 6 with adaptive voltage systems.
  • Cables and connectors — satellite cables of 5 m or 7 m; CHAdeMO outputs limited to 125 A and available only on a dual satellite with CCS2 and CHAdeMO; CCS2 above 300 A goes to a person to confirm the cable and terminals.

Any configuration of these power units with Satellite V2 outputs is in scope — not only the scenarios pictured here. Not covered: prices (no public price list was found, so this validator produces no price build-up or line-item quote), grid connection and fuse sizing, output voltage and power sharing between outputs, the C800 power unit and other satellite versions, liquid-cooled cables, software tiers, installation and service terms.

The AI sales agentBuilds the charging site configuration 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
Module count that depends on the cabinetOnly with care
Each power unit holds a different number of 50 kW modules, so the limit depends on the cabinet chosen and needs a rule per cabinet.		The cabinet and the module count arrive together and are checked on every call.
Output count that depends on the voltage systemOnly with workarounds
A dual satellite counts as two outputs and the limit is 8 or 6 depending on the voltage system, so the count and the limit depend on several choices at once.		Satellites and voltage system are in one request; outputs are counted and compared with the limit on every call.
Connector limits across linesOnly with care
CHAdeMO current and CHAdeMO availability on dual satellites relate separate lines of the quote, which needs cross-line rules.		Connector, current and satellite type are checked together on every call.
Stated power that must match the modulesOnly with care
A stated figure is a free-entry field; a rule can compare it with the installed power, but someone has to write and maintain that comparison.		The stated power travels with the configuration and is compared with the computed power 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.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a configuration for a DC fast-charging site: a power unit of 50 kW power modules, the charging satellites hanging off it, the cable length, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published data sheet limits 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 a Kempower power unit: a single-cabinet C501 with 6 power modules, 4 single and 3 dual charging satellites with 6 m cables. The quote states 400 kW of installed power. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings, all in one answer. The quote has 6 power modules of 50 kW; the selected power unit takes between 1 and 4. The quote has 10 charging outputs (a dual satellite has two); one power unit supports at most 8 (8, or 6 with adaptive voltage). The site needs 350 kW of charging power at peak; the installed power modules give 300 kW. The other two are on screen.
    6. 
      
  6. The validator returned five 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 stated power that must match the modules, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the power unit to C502, the power modules to 8, the dual satellites to 2, the cable length to 7 m and the site demand at peak to 380 kW.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All five earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Five problems caught in one call, fixed in one pass, 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.
