An AI sales agent's Series 7 charger order, checked before it goes out

An AI sales agent prepares an order for commercial Level 2 EV chargers: head-unit model, ports, connectors, charging current, supply voltage, service panel breaker, cable length, site conditions and the total charging power it states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures Blink Charging publishes for the Series 7 (ISO model) and returns a verdict, every reason and the figures it computed.

Scope: Blink Series 7 (ISO model) commercial Level 2 chargers: models, ports, connectors, current and power per port, breaker limit, cable length and operating environment. See everything this validator covers

This validator models an order for the Series 7 (ISO model) chargers, in the 80A Model 780 and 48A Model 748 versions, based on the public Blink Series 7 product sheet and sales sheet, not just the scenarios shown below.

  • Models, ports and connectors — the Model 780 in single or dual port with J1772 or NACS connectors, and the Model 748, which is dual-port and J1772 only. The seven published product codes are not themselves looked up.
  • Current, voltage and power — charging current up to 80A (Model 780) or 48A (Model 748) per port, 208 or 240 VAC supply, and a service panel breaker no larger than 100A (Model 780) or 60A. Power per port is current times voltage, and the total charging power the order states must equal the computed total.
  • Cable and site — the cable lengths the sheet publishes (23 ft, and 25 ft for the Model 748), the -30 to +50 degrees Celsius operating range and the 6,560 ft altitude limit.
  • Options — the card reader (the sheet lists contactless, magnetic and EMV payment for Model 880 only, not the Series 7) and Tesla vehicles on J1772 ports, which the sheet says need a Tesla adapter and so go to a person.

Any Series 7 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Blink does not publish list prices, so this page shows no price build-up), other Blink models, networking and software plans, installation, incentives and the Model 880. The mounting choice and cable management system are carried in the order but have no rule.

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
Only the models and versions the sheet lists (Model 780 and Model 748)Only with workarounds
The 48A Model 748 is dual-port and J1772 only while the Model 780 is single or dual with J1772 or NACS, so a rules-based CPQ needs a compatibility table or one rule per version, edited whenever the sheet changes.		Model, ports, connectors and cable arrive in one request and are checked against the published limits on every call.
Current, voltage and breaker limits that depend on the modelOnly with care
Each limit differs by model (80A and 100A, or 48A and 60A) and is compared with an entry on another line.		The model fixes the limits and every comparison is made on every call.
Total charging power the order statesOnly with care
The stated total is chargers times ports times current times voltage, so a rule has to recompute it and compare.		The stated total is a field in the request, compared with the computed one 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 person often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases
Click to expand
    
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.

    
1The order sets 49 amps per port; the current must be above 0 and, for this model, configurable up to 48 amps per port.
2The order sets 81 amps per port; the current must be above 0 and, for this model, configurable up to 80 amps per port.
3The supply voltage is 480 V; the Series 7 input is 208/240 VAC.
4The order specifies a 101 A service panel breaker; the sheet gives 100 A as the maximum for this model.
5The order specifies a 61 A service panel breaker; the sheet gives 60 A as the maximum for this model.
6The 48A Model 748 is published as a dual-port charger only; the order lists 1 ports per charger.
7The 48A Model 748 is published with a J1772 connector only; the order asks for NACS connectors (NACS ports per charger: 1).
8A Series 7 charger has one or two ports; the order has 3.
9NACS ports per charger (2) cannot be negative or exceed the ports per charger (1).
10A cable length of 25 ft is not published for this model.
11A cable length of 30 ft is not published for this model.
12The sheet lists contactless, magnetic and EMV credit card payment only for Model 880, not for the Series 7.
13The site ranges from -5 to 51 degrees Celsius; the Series 7 operates from -30 to +50 degrees Celsius.
14The site ranges from -31 to 38 degrees Celsius; the Series 7 operates from -30 to +50 degrees Celsius.
15The site is at 6,561 ft; the Series 7 operates up to 6,560 ft.
16The order states a total charging power of 134,400 watts; the settings give 153,600 watts.
17Tesla vehicles will use J1772 ports; the sheet notes that a Tesla adapter is required, so a person should confirm the customer accepts that.
18The order has 0 chargers; at least 1 is needed.
19The order sets 0 amps per port; the current must be above 0 and, for this model, configurable up to 80 amps per port.

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 commercial Level 2 EV chargers: head-unit model, ports, connectors, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures Blink Charging publishes for the Series 7 (ISO model) 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 6 Blink Series 7 Model 748 chargers with one port, NACS connector, set to 80 amps per port on a 240 V supply. The site ranges from -5 to 38 degrees Celsius at 500 ft. The rest of the request is on screen. The quote states 115,200 watts of total charging power.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with four findings, all in one answer. The 48A Model 748 is published as a dual-port charger only; the order lists 1 ports per charger. The 48A Model 748 is published with a J1772 connector only; the order asks for NACS connectors (NACS ports per charger: 1). The order sets 80 amps per port; the current must be above 0 and, for this model, configurable up to 48 amps per port. The other one is on screen.
    6. 
      
  6. The validator returned four 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 current, voltage and breaker limits that depend on the model, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the model to Series 7 Model 780.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All four earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Four 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.
    14.
