Re: Charging Question / New Spark EV Owner

Sun May 12, 2019 4:37 pm

Here's another clue: my car honks 4x in a row when plugged in to charge instead of 1x, but the charge light goes to solid green very quickly and it begins charging immediately.

I took the advice of another poster and tested the 120v charger it came with, and that charger DOES appear to follow the schedule. However, when I plug in at ANY level 2 charger, it ALWAYS starts charging immediately. I don't have fast charging.

So my follow-up question is: is it normal for public level 2 chargers to start charging immediately and ignore the schedule? If yes, then maybe my car thinks my home 240v charger is a public charger - does that make sense?

On page 9-38 of the 2014 Spark EV Owner Manual it states "Solid Green or Slow Flashing Green, four horn chirps, Action:Reason - Insufficient time to fully charge by departure time".

The fact that you experienced a solid green light, four horn chirps and charging starting immediately suggests the car thinks a full charge cannot be achieved by the completion time you have programmed. If you disconnected and reconnected, it may be possible the car reset the charging start time and then calculated there was not enough time to fully charge the battery by the departure time you had programmed. Try setting the charge completion time at least 8 hours beyond the time you plug back in and see what happens.

Thanks for the reply. I think you're asking me if I'm disconnecting and reconnecting the charge cable...every time I plug it in?

I can confirm the charge completion time is set for 12 hours from the current time the car is plugged in. I have more clues though!

1) While the car honks 4 times when plugged in in Rate/Departure Time mode (departure time being set for 12 hours later), it only honks 1x when in immediate charge mode

2) Certain L2 chargers, after being plugged in, are completely unrecognized. and nothing will happen. "Waiting for vehicle" displays on the charger and the charge light on the Spark remains off.

a. 1 horn chirp is normal in the Charge Immediate mode.

b. I have my 2014 Spark EV set to Departure Time charging with the departure time set to 11:15 am every day of the week. I am using my L1 EVSE and I manually set the charging rate in the car to 12 amps. I did not plug into my L1 EVSE last night and I measured my SOC this morning. It was 76.9% or 12.45 kWh (76.9% x 16.2 kWh (current battery capacity). I just plugged in and I expected to hear four horn beeps since there was not enough time to fully charge by 11:15 am. But, I only heard one horn beep, charging started and my completion time on the drivers display is now 1pm which is just about when I expected to have a full charge.

I am soooooo confused! :?: I guess it is possible that some of the software updates have changed what happens during charging. My 2014 Spark EV is current with all software updates for which I received notifications from GM.

Yea I'm in the same boat. My horn chirps and charging behavior does not match what is defined in the owners manual.

Are you digging deep into the menus for these functions?
Used '14 2LT w/ DCFC. +69 K miles.
Mostly free charging! Only one LONG visit to the shop....
GM needs Modern Troubleshooting tools for Modern EV's.
3 step Trouble Tree, 2nd guess not covered by warranty and cost $800. 3rd guess fixed the problem.

Honestly the menus don’t let you go deep enough. You can’t set a charging start time directly. You can only do it indirectly by setting peak/off peak times or a setting a stop time and doing the math.
You can’t set the charge percentage you want it to stop at.

So to answer your questions yes I am very familiar with all the menus and their effect on charging and unfortunately no dice

But can't you turn off the horn alerts?
I don't know. I never used charge times, but I did turn off all the honking.
