Marlowe, yes try to be easy on the battery. Should only use it continuously at 1 bar of power or less. If the road/incline required extended 2 bars of power, start the engine especially if its hot then go back on the battery. On the highway for sure start the engine and save the battery for later.
Things to think about:
a) if you are driving a trip 100% EV, take the shortest way there, avoid highways. If you have to go on the highway, limit your speed to 45-50mph in EV power.
b) in 100% EV trip also, any hills limit the power to 2 bars tops, or 1.5 bars and let the car slow down some up the hill. You can try to pickup a little speed before the hill and let it slow down in the climb.
c) if the engine is already in use and hot, always start the engine when the power demand is higher. To climb a hill and then you can go back on battery, or to go on the highway.
d) when you DO start the engine, you have to actually WAIT until the engine is hot before you can use the power. If you try to use the power right away you're actually stressing out the battery by taking 3/4 of the load from the battery and maybe 1/4 from the engine as its limited to 1500 rpms max. Look at the engage screen, you will see the battery load and engine load. Wait until the battery load drops off before stepping on the gas. What does this mean?
What it means is that when you get on the highway and switch to EV later, you need to STAY at 45-50 mph for a couple of minutes until the engine warms up and actually takes the load before you speed up to 65mph. This is only from a cold start. Once the engine is hot you can get on the highway from a side street and switch to EV later and go. If its cold, wait for it to warm up first. Its not EV later and you're on the engine, its EV later and you're warming up the engine preparing it to take the load off the battery and during that time you're STILL on the battery! Once warmed up, wait for the next downhill and then speed up to 65mph - never try to accelerate uphill, its inefficient you want to keep the engine at 2 bars of power while accelerating for most efficiency. It will take longer than "normal" to get up to speed but your MPG numbers will shine and you'll be in the max efficiency range of the engine.
Hope that helps!!
As far as charging, don't charge during the day in the sun. You can go out in the evening and charge in the evening or night no problem. Just avoid charging in the heat. Also another tip is to flip the right seat seat forward and remove the hatch for the HVB disconnect to let the heat out while charging. Also roll down the windows in the car as if you don't it gets hot inside and the hot air circulates around and warms up the HVB (not what you want). In my garage my windows are down while charging in the summer all the way. On the road they are down 1 inch each. At home if I'm charging and I hear the fan racing, then I stop charging and wait for a later time. A fast fan means the HVB/charger are hot, not the best time to be adding more heat charging. I realize you don't always have a choice, but given a choice, if its hot, wait for later.
Don't charge the battery every night to 100% if you don't need it the next day. If its all used up let it rest the day you get home (or night). Wait several hours maybe even until the morning for it to cool, and then charge it a little bit in segments so you're not full but you're not empty either. Right now my Angel (cmax) is sitting at 41%. For example I came home Saturday night, it was 0%. On Sunday morning I charged it to 10% and left it as I knew I needed to go to the grocery store later and 10% is enough to get there. Once at the store Sunday evening, I plugged it onto their HV charger while shopping. It went up from around 0 to 50%. Then I drove home and I got 41% left. I let it sit like that, since I didn't need to use the car today. Sitting partial charge is better than sitting for a couple of days at 100% charge. And, at partial charge its only a couple of hours from a full charge. So if and when I need to go out, I make a determination of how much charge I need, and charge it before I go. Might be 100%, might be nothing if I'm going somewhere to a public charger, or might be something if I can't reach that charger with 41%. I know how much % I need to go somewhere, so I'll put in what I need and go. If there is no charger at the destination then I put in 100% and go. Make sense?
