Well I am new driver for EV and still learning. Just wanted to know what's average distance it covers with single full charge with 60% city traffic with 50% AC and 3 passengers..
With a single passenger and blower on 1 AC on 2 and driving typically with 1 to 2 bar efficiency i usually get more than the rated 1.2km per percent SoC ( on e20) 1.3km to 1.4km per percent SoC is common. In summer now I have to increase the blower to 2 AC to 3 to 4 and then it reduces to 1.2 km per percent SoC Note that I use boost very sparingly.. and drive efficiently.. e.g if I am approaching a red light I know will take some time to change I just coast on regeneration slowing down gradually rather than keeping a higher speed and using the brakes at the end.
So to answer your question.. with AC at 50% of full if you drive efficiently, looking at regeneration opportunities I think you should still be able to get the rated 1.2km per percent SoC plus minus 5%. From 1 to 3 passengers does make a slight difference. But note that you will spend slightly more energy on accelerating but will also gain more energy back in regeneration for this additional weight.. AC will consume bit more also for 3 pax
Efficient Driving 1. The most important factor for getting the maximum range out of your e2o battery is to keep a very close watch on the efficiency indicator on the odometer display screen. 🚗💨 1. To ensure best 'mileage' and yet maintain a tolerable driving speed of 45-55 kmph, one must always drive at 2 bars. 2. It is relatively easy to drive at 2 bars at that speed but will need a lot of patience while accelerating at 2 bars. The normal tendency is to accelerate quickly by stomping of the accelerator pedal and on achieving 45-50 kmph, ease off to drive at 2 bars. This should be avoided if you want to get better efficiency. 3. Any driving above 2 bars will not give you the company promised range at all. 2. Driving barefoot / in socks / with lightweight footwear helps as many times the accelerator does not get inadvertently pressed due to heavier shoes. The idea is to literally caress the accelerator. 💛 3. Maintain optimum pressure of 32 psi in tires. 🚙 4. It has been stated that alloy wheels also help with efficiency. I don’t have alloy wheels so cannot say. However, alloys for the e2o can be procured from local vendors. 🚕 5. As far as possible, especially while coming down slopes, take your foot off of the accelerator and let the battery recharge using the magic of regenerative braking. ♻ 6. During hot summers, try and park car in the shade. This ensures that battery cooling load is minimized and hence pressure on battery is also lessened. ⛅ 7. Factors which affect battery range drastically: 🔋 1. Passenger weight 2. AC 3. Sudden acceleration 4. Driving at higher than 2 bars 5. Boost mode 6. Wipers 😊👍🏼
Can i charge the e2o's batteries using only solar power by adding sunroof on the car?
Here are the problems with this Idea. Most solar panels would add too much weight to an EV to be worthwhile. Some newer, lighter, flexible PV technology could generate power for interior climate control or minor tasks, but not enough to power a car a significant distance. So you gotta have that plug. And 95% of the time in a week, the car resides in basement lots. And there is no sunshine there. So there is no benefit Also it is recommended to park a lithium-ion based Electric car in the shade rather than in the sun. The Indian summers can be oppressive to the Lithium Ion battery pack. So its not recommended to park in the sunlight. Bad idea. Ok. One can argue that the car can charge during movement. But the voltage that gets generated will be very minimal. Also this would only add to the cost of an already expensive car. So your best bet is to have a solar power system at home or work and charge ur electric car using solar power.
why does the e2o Plus electric car get the SAFEMODE error message?
This answer is credited to - Mr Sameer Godbole, electric car owner of Pune
SAFEMODE is primarily due to imbalanced Main Battery.
If you observe charging, you would see that car charges till 95% and 104km (For 110km E2O+ car). This happens approx. 1%/3min rate. When SOC is reaches 95% car is charged but batteries are not balanced. So it starts balancing process which takes about 50min to 1 hour. Balancing is required as all batteries are not equal and as a result some are overcharged and some are undercharged. Balancing ensures that all the batteries are equally charged by discharging overcharged batteries and topping up undercharged batteries. If the car has not recharged to 100% in 3 consecutive cycles then the weaker batteries get commutative effect of undercharging and has seriously lower energy level, some times even down to 30% compared to other batteries. In such case if car is driven to 30% SOC one of the undercharged battery is unable to provide enough current required for drive the car. When this is detected by IEMS, it issues SAFEMODE and halts to car to avoid damage to batteries. It is necessary at-least one full cycle should charge car to 100% if you have 2 partial charging cycles.
Charging methodology stated above also applies to fast-charge. When car reaches 93-95% it stops charging car. Even the manual also says 0-95% in specified time (E2O+ P2 and P8). Why it does not say 100%, because it can never charge to 100% using fast charge method, as during fast charge, it do not carry rebalancing process so every two fast-charge cycles there has to be one normal charging cycle to 100%. After finishing fast-charge if you connect to standard power (15amp plug) it would carry out rebalancing of batteries which would take 50min to 1 hour. Also it would consume only one charging cycle, that is fast-charge + regular charge (rebalancing), if you could do it without entering drive mode in between fast-charge and regular-charge cycle.
It is also necessary to charge once charging overnight (minimum nine hours in at-least every 3rd day). Which is critically important for the health of AUX battery.
It is also observed that AUX battery also can cause SAFEMODE. This problem occurs randomly. Typical symptom is Car when started, you get 0% SOC and 0km DTE, with a loud and long beep. Then it boots cluster (goes dark and then turned on) may return proper SOC and DTE. Sometimes this is may happen for multiple times and then proper SOC and DTE are shown. How ever when we move gear to F/B it shows E mode. And the creep mode is off. In such condition it is necessary to switch off car and restart again. And then it works properly.
It is again necessary to charge the Car at-least every 3rd day (at-least) overnight (9 hours or more not necessarily at night).
