Battery state-of-charge (SOC) includes the amount of usable energy currently stored in the battery (i.e. how full is the tank?), whereas battery state-of-health (SOH) is a measure of the battery’s performance relative to a brand new one of the same make, model, and model year.
Ask about the degradation of the battery over time, remembering to check in on the expected lifespan of your EV battery and that it’s covered by a warranty. Ask your dealer, how long will this battery last and what will it cost to replace it? Typically, manufacturer warranties for EV batteries last around 8 years so use this as your baseline. Be sure to include those costs in your end calculations.
2. Charging options
Most new range EV’s come with the option of a dedicated EV charger than you can mount to your garage wall. If you do need a quick recharge, it's worthwhile investing in an onboard charger. Onboard chargers guarantee that you’ll get the most out of your charge in a short period of time. Be sure to get a qualified Electrician in to check on the installation of your wall charger and any connections between your vehicle and home. Keep in mind too that the costs of a wall charger can range from 0 to $2500 depending on what you choose.
The other thing to consider is the public charging network available in your area. Make sure the vehicle you are choosing is compatible with the network. Over time this will become less of an issue but due to the relatively new charging network in Australia, it’s something to be mindful of.
For more information on what’s available in your area, check out the EV Council charge map.
One of the most critical factors to consider is just how far you want to travel in your new EV. While ranges can go up to 500 Km on a single charge for models like the Tesla Model S, daily stop-starting of the average commuter will have an impact on the battery life.
