Check out some of the discussion here https://www.mychevysparkev.com/threads/chinese-diesel-heater-mod.9556/ really quick, the windows are fogging up because the relative humidity at the panes is 100%. Heat will warm parts of the window up and increase the dew point, but you're battling a...

The TPM sensors use a coincell, CR2050 rated for high temperatures and they should run down over 6-8 years. However, they are not typically serviceable because the battery and circuit board are both fully potted for a harsh environment (vibration heat moisture). These sensors could last longer...

I haven't personally tried the 150W heaters but it would have to be very close to me and quite well placed to have a direct warming benefit. On the other hand, having a small tank of diesel to heat with is like having a second spark battery just for heating. If I had to try 12V electric heating...

I don't think what the prime mover is, whether it's an electric motor or a combustion engine, matters so much (yes the toque is very different). I think the strategy, transmission, and tires matter far more. A fair comparison might be to ask whether a Chevy Spark would have a better time in the...

Tl;dr I think it's just a matter of the preheating stage of cabin heating that's throwing you off on cold days. Even though it's electric, the Spark EV doesn't provide instant heat because it's designed to heat a water coolant reservoir first. If you already assumed as much, then pardon me, we...

Once the pack drops to freezing temps it will run the 2.5kW battery heater while charging or driving until temperatures are 3-4 degrees above it. While unplugged and off the pack can go sub-zero and no action will be taken. Im waiting for winter to confirm this again but I believe departure...

This link is safe, but we've had online owners manuals available forever. What would really help is downloadable service manuals... The link takes you to a 2013 gas spark manual, not EV. If the user is a bot, they're getting smarter.

Welcome, 2014 EV in Vegas! I like the name, very descriptive. Though I might have a hard time referring to you!

I'm drawing a blank on sensor location, but you might be interested in a post I made about how coolant and HVAC refrigerant are related to battery cooling. https://www.mychevysparkev.com/threads/effects-of-fast-charging-and-efficiency-miles-kwh.9553/post-29928 In other words it really could...

Yeah of course Kermit has no idea what he's talking about for a 2013 spark... This is the Spark EV forums for 2014-2016 models!

I'll keep my eyes open for something like that, but I have a feeling rather than a highly integrated single centralized unit, the more typical solution will be single independent units, or a stack of 16-cell or greater units that communicate via serial data communication...

I want to know too. It would be helpful to dig into it. I have a strong feeling the logs were given by the DCFC tech support to the user after they shared their charge session ID, where the user could then share these logs to the OEM dealer to troubleshoot or replace modules. Otherwise the PLC...

Are these machine answers or a legitimate person reporting at the scene of the forum post?

They're definitely around. Reach out to https://batteryhookup.com/ , https://www.greentecauto.com/ , maybe EV West https://www.evwest.com/catalog/index.php . There are also DIY EV forums where members have all sorts of knowledge and connections to share. There are a lot of companies popping up...

Something seems wonky for sure if your data isn't updating or displaying persistently. PID 2243A5 is correct according to the spreadsheet. Is there a chance the .CSV is messed up? That or a communication issue polling all the data... There isn't a custom PID for those, but I have working...

Correct, the BMS presumably uses passive balancing involving a switched shunt resistor for each of the 96 / 112 groups (simple and cheap), and not between cells, so the only option to balance is to do so while charging to 100%. I would hazard to guess the reason EVs don't balance with their...

Time snip 1 Time snip 2 prof John Kelly goes over the battery construction and cell measurement/balancing in the Chevy Volt (similar architecture to Spark EV). What does the BMS do? The BECM (Battery Energy Control Module) monitors the state of the 96s2p (96 series and 2 parallel) cells in...

Welcome to the forums, juanricos!

The biggest challenge is for Spark EV owners who can't stay plugged in overnight, and temperatures start dipping below 32ºF. This is because below freezing, lithium chemistries can't be recharged, and with regen, this would cause cell damage. So the car limits (but still allows) the regenerative...

I'm not sure if battery conditioning includes cooling. I've only seen it count up in very cold weather. Also with 80 kWh since your last full charge the resolution on battery conditioning is only 0 kWh or 8 kWh at 0%/1%, very poor resolution to make heads or tails of it, but if there were other...
