Fatti chiave dell'applicazione

Settore


Test in linea dei riscaldatori HV in base alle fasi di produzione

Applicazione


Verifica del funzionamento dell'elettronica di controllo.

Parametro misurato


Tensioni da 100 a 900 V CC e corrente corrispondente

Requisiti chiave


Vengono applicate tensioni fino a 900 V CC, a seconda del prodotto testato.

Le alte tensioni devono essere misurate in modo sicuro e accurato, durante i test di assemblaggio/in linea

Flessibilità nella selezione della tensione d'ingresso necessaria per le diverse configurazioni applicative

Conferma della funzionalità dell'elettronica di controllo

Descrizione dell'applicazione

Il processo di produzione degli HVH prevede numerose fasi, alcune delle quali sono manuali. Vengono eseguiti diversi test in linea, in base alle corrispondenti fasi di produzione. A seconda del tipo di riscaldatore, vengono applicate tensioni da 100 a 900 V CC direttamente sull'unità dello strato riscaldante. Allo stesso tempo, questa tensione e la corrente corrispondente vengono misurate per verificare il funzionamento dell'elettronica di controllo. Poiché esiste il rischio di scosse elettriche, durante questo test non è possibile eseguire alcun montaggio sul pezzo.

Requisiti dell'applicazione

Per ottenere risultati di prova affidabili, è importante utilizzare apparecchiature di misura precise e affidabili. L'uso di apparecchiature di laboratorio in un ambiente di produzione non è sempre pratico. Per questo motivo, per i banchi di prova di fine linea, oltre che per le fasi di ricerca e sviluppo, vengono utilizzati dispositivi di alta qualità collaudati in applicazioni industriali.

Perché Knick?
Il Knick P29000 è un trasduttore di tensione in grado di misurare in modo sicuro tensioni fino a 1000 V CC. La precisione è garantita da un errore di guadagno < 0,2% del valore misurato. La sicurezza è garantita dall'isolamento elettrico basato su un trasformatore a 3 canali a una tensione di lavoro di 1000 V CA/CC. Un'ulteriore sicurezza elettrica è dimostrata dalla tensione di prova del P29000, pari a 5,4 kV CA. La flessibilità è garantita dalla possibilità di selezionare gli intervalli di ingresso e di uscita tramite i dipswitch integrati.

With the help of hardware in the loop (HIL) tests, prototypes of devices like the traction inverters, for example, can be evaluated in various battery, load, and error situations without having to test the converter itself on test benches or in vehicles.
Test systems generate control voltages in a battery model in order to simulate temperature conditions for battery management systems (BMS) and evaluate the temperature management of the BMS.
During battery tests, the charging and discharging operations (battery cycles) are continuously simulated in a HIL (hardware in the loop) configuration that corresponds to the typical use profiles when the electric vehicle is in operation. In the process, a series of parameters are measured, including capacity, battery efficiency, and self-discharging.
For battery electric commercial vehicles, there is a quick-charging option via pantographs. This requires a contact between an external infrastructure system (with movable pantographs) and permanently installed charging rods on the vehicle roof. A DC roof container contains components that check the charging connection and the corresponding voltage, and establish the connection to the other on-board systems.
The test cells used in the manufacturing process are often protected by protective enclosures and voltage detectors.
