BOSCH Powerpack – Powertube – Analyse du Bus CAN – Partie n°2

BMS Bosch Poxertube analyse Bus CAN TLE6251
Sur les VAE Bosch le système est composé de 3 éléments qui communiquent entre eux par l'intermédiaire d'un Bus CAN, Le display, le contrôleur ainsi que la batterie. Voyons ici les trames CAN échangées

TLE6251 Générateur et lecteur du signal CAN

Ce composant s’occupent de générer et de récupérer les signaux CAN sur le Bus. Sur l’image ci-dessus il est possible de le voir sur la carte BMS d’une batterie Bosch Powertube.

Afin de pouvoir suivre un peu la conversation CAN, il va falloir connecter l’ensemble moteur, Display et batterie.
A l’aide du Display Bosch ou de la batterie on va allumer le système.
Il suffit alors de connecter un analyseur de signal CAN sur la prise femelle que l’on trouve par exemple sur les vélos équipées d’une batterie porte bagage.

 

Analyse Bus CAN sur prise Bosch Powerpack ou Powertube

Le fil vert correspond à H.
Le fil jaune correspond lui à la ligne L

"Sniffer" le signal CAN

On lance alors l’analyseur et on enregistre l’ensemble des trames sur le Bus CAN Bosch.

Voici un petit extrait d’une seconde de la conversation …. plutôt bavard le Bus CAN !!

La colonne de gauche correspond à la date
La seconde à l’ID du signal CAN
La 3ème indique la longueur du signal
On trouve ensuite les divers octets de données en Hexadécimal pour chaque ID

Petit résumé des échanges sur le Bus CAN du système Bosch

Une seconde d’écoute suffit à percevoir la majorité des signaux car ceux-ci se répète avec une fréquence comprise entre 100 et 500 ms.

Voici donc la liste des ID
0x101
0x10A
0x111
0x151
0x1C
0x203
0x205
0x206
0x210
0x211
0x220
0x221
0x2AA
0x36
0x37
0x3B
0x3C
0x48
0x59
0x8C
0x9A
0x9B
0xC7
0xD0
0xD1
0xD2
0xD3
0xF1

Ces divers signaux peuvent provenir d’un des 3 éléments.
Reste plus qu’à associer chaque ID a une information précise échangée.
Ceci sera l’occasion d’un nouvel article mais en attendant voici un petit exemple avec les informations envoyées avec l’ID 0x111

08:44:30.051 111 7 0 0 4E 20 0 72 2D  

On peut y lire que la batterie est chargée à 45%.
Intéressant non ?
