-Older cars will have largely mechanical or individually wired systems for brakes and instruments etc. These systems will largely not care what power plant is installed and keep working. Later cars will likely use LINBUS or CANBUS. And the most recent cars might use formats like FlexRAY. In order to re-use existing systems you will need to find a way to integrate your new drivetrain with the existing systems. For some vehicles, this work has already been done and may be included in the code for the ZombieVerter. For others there might be standalone solutions, or existing knowledge on the forum/wiki.

	Batteries are most easily mounted in simply-shaped boxes. Consider where you might put these when choosing a car. Will you give up the boot? Is there space under the bonnet with the ICE removed? Really small cars can be challenging.		Batteries are most easily mounted in simply-shaped boxes. Consider where you might put these when choosing a car. Will you give up the boot? Is there space under the bonnet with the ICE removed? Really small cars can be challenging. Google underbody pictures of cars that you're considering, especially if variants with alternative fuels (PHEV, CNG etc.) exist.

	Think about the size of battery pack you need. A relatively small hybrid pack (<10kWh) can make for a very capable city runabout. But for longer ranges you would need a larger pack or multiple packs.		Think about the size of battery pack you need.

Fleshed out component options

	~~You will want Integrated components that fulfill multiple functions in your build at the same time:~~

	- cheap ~~motor & inverter~~, ~~ideally combined units ([[Toyota Prius Gen2 Inverter]], [[~~:~~Category:Nissan\|Nissan]] LEAF "stack", [[Mitsubishi Outlander Rear Drive Unit]] & [[Mitsubishi Outlander Rear Inverter\|Inverter]])~~		==== Motor and Inverter ====
			To keep things simple (and cheap), you will want integrated components that fulfill multiple functions in your build at the same time. Proven combinations include:

	~~- cheap batteries, this will be your biggest expense (~~[[Nissan ~~Leaf BMS~~]]~~, BMW i3, repurposed PHEV batteries)~~		* [[Toyota Prius Gen2 Inverter]] and transaxle
			* Toyota Prius Gen3 Inverter and transaxle
			* [[:Category:Nissan\|Nissan]] LEAF "stack"
			* [[Mitsubishi Outlander Rear Drive Unit]] & [[Mitsubishi Outlander Rear Inverter\|Inverter]]

	- ~~smaller battery packs~~ can ~~be compensated for by enabling [[Rapid Charging\|rapid charging]]~~		==== Batteries ====
			Batteries are likely to be your biggest cost other than the car. Perhaps the cheapest option is re-use a PHEV pack from a BMW or VW, though the market is fluctuating all the time. This will typically provide you with 8-12kWh of batteries in a small number of compact modules, interconnects to hook them up, and a 'safety box' from which you can re-use the contactors, fuse, pre-charge resistor and relay.

	~~- DC/DC converter; this replaces~~ the ~~alternator to keep the 12v systems running~~ in ~~your car~~. ~~([[Mitsubishi Outlander DCDC OBC]] )~~		Alternatives would be the Nissan Leaf battery modules and BMS, though these can be more work in repurposing.

	- ~~charger ( integrated into existing units, such as~~ Nissan Leaf PDM, ~~Mitsubishi Outlander charger & DCDC, Prius Inverter & charger )~~		==== AC Charging & DC-DC Convertor ====
			Low power chargers from the likes of the [[Mitsubishi Outlander DCDC OBC\|Mitsubishi Outlander]] are available relatively cheaply and also provide an easy-to-use DC-DC converter. Likewise the Nissan Leaf PDM gives you everything you need.

			The Prius inverters can also be used to provide charging and DC-DC conversion for a truly compact option.

			==== DC Charging ====
			Smaller battery packs can be compensated for by enabling [[Rapid Charging\|rapid charging.]] ChaDeMo and CCS are both now available as DIY options, using a variety of control options - notably the BMW i3 LIM for CCS.

+Cars can be converted to electric at very reasonable cost, as long as you have the skills and realistic ambitions. Pay attention to the warning above.
-=== Rule number One ===
+With that out of the way, here’s how you might go about building a cost-effective EV conversion.
-<u>Don't buy a rust bucket.</u> This is the quickest route to making a cheap conversion into an expensive one. You would be spending time and resources on fixing additional parts of the car and are not able to focus time and effort on the actual conversion process. Ideally start with a reasonably maintained, working car (some funds recovered from component sale) or one that would be uneconomical to fix (big engine/gearbox overhaul required).
