ovms

The Open Vehicle Monitoring System - allows a user to connect to the CAN bus in a vehicle so that the user can view and monitor several parameters of vehicle operation, such as state of battery charge for an electric vehicle. The system includes hardware (a board that connects to the vehicle), a server, and mobile device software. Early work on this system was done by enthusiasts of the Tesla Roadster ; the system is also being adapted for use with the Nissan LEAF, Chevrolet Volt / Opel Ampera, Renault Twizy, Think City, Tazzari Zero, Mitsubishi i-MiEV and Kyburz and has a Generic OBDII module. OVMS has similarities to Nissan's proprietary CarWings system.

    Hi all, I was wondering if the guys manage to get the OVMS preheating function to work in the 2019-2021 ZS model? I know there was a password needed issue, but I can’t find any newer status regarding this. Br., Niclas

    OVMS readings. Starting SoC 50%. 4 hour charge so would have one hour of balancing A01 BMS release so the early BMS gate fix Never seems to get to the highest reading on OVMS, which was typically 98%+for most. SoC not that far off though. 40k OG ZS from the original 1000 batch in 2019 OVMS#...

    OVMS module and MG dealers?

    I have an OVMS module that I occasionally use to check the SOC remotely. (I also used it on a long journey to feed ABRP with live SOC info) Wondering if it's advisable to remove it before taking the car into the dealer for servicing. Given polling with the car locked tends to set off the...

    Replacing MG ZS EV 12v lead acid with Lithium Phosphate battery (LiFePo4)

    After 2+ years, my MG ZS EV 12v battery died. Rather than replacing it with a lead acid battery, I decided to go for a LiFePo4 or Lithium Phosphate battery. After the battery died, I jumped with a smaller LiFePo4 battery and it came back to life. So I was pretty sure that it would work. Plus I...

    SMS Alert setup in OVMS?

    Hi, I'm using an OVMS unit with my ZS EV. All looks good - I can get data to the app, I can see things like my SOC and it would appear that the sim card I've inserted has been recognised and functions. I understand that I can send myself SMS messages to tell me when charging has reached a...

    OVMS 3.2.017 EAP and Edge Builds

    Based on personal experience, the above recently started keeping the car alive, charging the 12V and in the case of the latest edge build, the 12V reading was 5.4kV! Returning to the main branch resulted in correct idle and shutdown of the car's systems.
