Our Australian team have received several issues reported with zappi scheduled charging integrating with BYD vehicles – particularly the Atto3.
Thanks to them for having found a workaround while the rest of the world waits for the EV to reach their markets.
We’re seeing customers plug their vehicles in on ECO+, and then during the Waiting For Surplus…
period of charge, the BYD will go to a ‘sleep’ mode to preserve the 12V battery. Current Zappi
features such as Plug-In Charge do not rectify this. It’s currently unknown precisely how long it takes
for the car to enter this state, but almost every case of this issue is when customers are leaving the
Zappi set to ECO+ to wait for their off-peak tariff during the night, so it may be upwards of 30
minutes, or a couple of hours.
The problem is on the vehicle side, and the only way to ‘wake’ the vehicle is to interact with it in
some capacity, such as locking or unlocking it. The current best workaround for the charging to
remain autonomous is to set synchronous schedules on the vehicle’s Reserve Charging feature and
the Zappi for when the off-peak tariff comes on.
From the BYD home screen, enter the vehicle seƫngs page by pressing the button in the bottom right corner of the screen.
From the BYD home screen, enter the vehicle settings page by pressing the button in the bottom-right corner of the screen.
Then, enter the New Energy menu from the right sidebar menu
Then, enter the Charging Settings menu from the top navbar
Then enter the Smart Charging settings
Turn Reserve Charging to ON and set a time that is very brief after the Zappi is set to start.
Hopefully, BYD will release a software update in the coming months to fix this problem. We’re aware of a couple of other instances with non-BYD vehicles that this can happen to, and it’s typically been plug-in hybrid vehicles.
