# EVC BMS Frontend

SvelteKit webapp for the BMS for Purdue's Electric Vehicle Club's high voltage battery.

## TODO:

- [ ] Build system to automatically push to BMS SPIFFS if connected?

- Display all faults (high voltage, big diff, etc)

	- And make it persistent

- Parameters/GUI inputs for all hardcoded values:

	- [ ] Name change (apSSID)

	- Voltage

		- [x] Per cell min [`vMin`]

		- [x] Per cell max [`vMax`]

		- [x] Average cell min [`vMinAvg`]

		- [x] Average cell max [`vMaxAvg`]

		- [x] Max cell delta [`vDiff`]

			- [x] Add bar

	- Temperature

		- [x] Per thermistor min [`tMin`]

		- [x] Per thermistor max [`tMax`]

			- [x] Doesn't apply to temp fet

		- [x] Max temp delta [`tDiff`]

			- Doesn't apply to FET

			- Not critical (no cutoff) but should throw fault code

			- [x] Add bar

		- TODO: 4 temps now

		- 2 new balance temps

		- [ ] Max FET temp [`tMaxFET`]

			- 50-80C

		- [ ] Max balance temp [`tMaxBal`]

			- TODO: implement into the UI

			- 40C restart

			- 50C stop

	- Current

		- [ ] Max instantaneous current [`iMax`]

		- [ ] Max continuous current [`iMaxCont`]

		- We will need to change some logic for this

		- NOTE: negative current is fine (charging vs discharging)

		- [ ] Better current bar

			- Maybe uses the abs for the width and a color for the direction

				- (And maybe different sets of colors for balancing vs monitor mode)

	- [ ] If BMS sees current being drawn and it shouldn't -> complain

	- [x] Logging speed [`logSpeed`]

	- Bypass

		- [x] Bypass enabled [`bypass`]

		- [x] Bypass voltage [`vBypass`]

			- Not critical

	- [ ] Battery/fault check rate

	- [ ] SPIFFS usage bar

	- Notes:

		- Defines for starting parameters in battery.h

		- Actually use the Parameters struct/dict when doing the checks

			- On the frontend and the Arduino

- [ ] Automatically create a graph from `log.csv`

- Save all past valid IPs

- Actually fix CORS

- Fix: 5 sec fetch timer?

	- The fetch seems to not go off at exactly 5 seconds??

	- [ ] Also it would be interesting to have an input for the fetch timer

- Svelte components (or snippets) for:

	- [ ] The collections of bars and bars (instead of repeating the same code)?

	- [x] And all the inputs

		- Did this with a component, might make more sense to use a snippet

- Appearance:

	- [ ] Better button colors

	- [ ] Use a table for stacked inputs so they all line up

	- In general, better CSS

	- Ex: better color diversity (and maybe some less aggressive colors)

	- [x] Update mobile CSS
