bl52krz Posted April 4 Share Posted April 4 I took my automobile to the service centre to investigate the cause of the continuous reduction in its battery charge. Initially, the car had a range of 26 miles on a full charge, but it has gradually fallen to 20 miles. The dealer successfully achieved a speed of 25 mph using their charger. What is the reason for this? Quote Link to comment Share on other sites More sharing options...
bentleygt77 Posted April 4 Share Posted April 4 My mileage has consistently risen to 33 miles. Quote Link to comment Share on other sites More sharing options...
xsports Posted April 4 Share Posted April 4 The range of my vehicle has decreased to 17-18 miles on a full charge, compared to the initial range of 25 or 27 miles when I originally acquired it. I believe the reason for this is due to my residence in San Francisco, a city characterised by several hills. The vehicle consumes more energy as a result of navigating these hilly terrains. Furthermore, the car's accuracy is improving as it continuously gathers data from real-world driving experiences. Quote Link to comment Share on other sites More sharing options...
stevenkeyte Posted April 4 Share Posted April 4 The displayed range on both the vehicle and the app is an approximation derived from other factors other than just the charge level. Therefore, there is no need to worry when it fluctuates. On one occasion, you may see an estimated range of 20 miles after charging overnight, but in reality, you are able to go 29 miles before receiving the "EV mode disabled" notification. If you do not see that warning during your regular driving, it is advisable to disregard the anticipated range number. The miles per kilowatt-hour (miles/kWh) figure provides more accurate and dependable information. Three key elements used in the computation of the range estimation are: Load refers to the level of effort or strain that the automobile is experiencing. Is it necessary to significantly raise or lower the temperature within the cabin? Does it exhibit increased velocity or navigate through significant variations in height or wind patterns? Electric vehicles are more susceptible to these factors compared to automobiles powered by petrol combustion. Ambient temperature refers to the current temperature of the surrounding environment, indicating whether it is hot or cold outdoors. The chemical composition of the high voltage battery allows for greater energy storage capacity at temperatures nearing 80 degrees. When the temperature drops significantly, it may seem like there is a significant loss of energy, but in reality, the energy does not undergo any physical changes and will rebound when the weather becomes warmer. Users of battery electric vehicles (BEVs) have seen a significant reduction of around 50% in their estimated driving range due to this issue. Battery State of Health refers to the battery's capacity to store and retain energy. Physical change is an inherent and unavoidable process that occurs gradually over an extended length of time with these particular batteries. Typically, this process takes a significant amount of time, which is why I think manufacturers that sell their products in the United States are obligated to provide a guarantee for the battery that lasts a minimum of 8 years. Manufacturers are becoming adept at avoiding this. Due to the lesser battery size in the PHEV compared to a full EV, I anticipate that any decrease in range, such as a 5% reduction, would be negligible and hardly noticeable, since it would only result in a difference of around one mile, which is insignificant. You need not be concerned about this matter for many years, if at all. For someone with a strong technical background, it should be feasible to get a measurement of the battery's state of health via the OBD port by using a suitable dongle device and application. I use Car Scanner, a well appreciated tool among electric vehicle enthusiasts. The software has connection profiles for a wide range of vehicles, however, the most similar one I could see for the CX-90 is labelled as "Mazda Skyactiv." With the use of this tool, I discovered some intriguing readings. However, I was unable to locate the battery State of Health (SOH) or the total energy, which are the specific aspects that pique my curiosity. I am eagerly anticipating the addition of a cx-90 or Mazda PHEV profile in order to expand the range of possible sensors. EDIT: ** Moderators: Based on past experiences, it might be advisable to create a prominent post detailing the decrease in range for plug-in hybrid electric cars (PHEVs) during colder weather. Within the BEV groups, there is a constant influx of postings from members expressing concern over the decrease in range, both real and projected, as the winter months draw near.

Ken_Lion Posted April 4 Share Posted April 4 I have not achieved a range over 25 miles with a complete recharge. That is the information shown when I start my automobile. Is there any action I can do to enhance the mileage and achieve the 30-mile range that others are achieving? Furthermore, I connect my vehicle to a power source located inside my garage, even though my automobile is positioned outdoors. Does not fit inside the dimensions of my garage. I am aware that temperature has an impact on the charging process. Is there any action I can do to provide assistance specifically during the winter season? Is it snowing? Is it safe to connect my battery pack to an outside power outlet, or would exposing it to harsh weather conditions be detrimental? I appreciate your assistance!

honeycut_mazda5 Posted April 4 Share Posted April 4 Severe weather conditions will impact the battery's lifespan. The capacity of a battery to store charge is influenced by cold weather due to chemical reactions, rather than being a problem of the battery itself. Connecting the vehicle to an external electrical outlet should have no impact, unless you are using an extension cord between the outlet and your charging cable. If you need to do that task, I recommend accessing the internet and purchasing an extended power cord for your automobile. Quote Link to comment Share on other sites More sharing options...
coolguy Posted April 4 Share Posted April 4 My internet connection consistently has frequent disruptions, occurring virtually on a daily basis. I am quite frustrated since I rented this automobile with the intention of reducing my petrol expenses, but it is not achieving that goal. During my daily journey to work. The maximum distance on a full charge is now limited to 14 miles. I feel somewhat deceived by my Mazda, or maybe I have acquired a defective vehicle. We welcome ideas from everyone. The dealership is uncertain about the cause of the problem. Quote Link to comment Share on other sites More sharing options...
torque2me Posted April 4 Share Posted April 4 During the first month of owning the vehicle, I have managed to get a maximum range of 26 miles on a full charge. However, it is important to note that the actual range may vary. I am aware that when I have 5 kilometres or fewer left, the battery charge depletes to 0 overnight, most likely as a result of the low temperatures prevalent in the Boston region. Nevertheless, when I examine the High Voltage Battery Monitor page, it will display a charge level ranging from 15% to 20%, but it will show a range of 0. While operating in Normal mode, I am able to generate electric power while coasting or when stationary, but I am unable to activate the electric vehicle (EV) mode.

coolguy Posted April 4 Share Posted April 4 Thank you for your prompt answer. Perhaps the chilly weather is the cause? Considering my current location in Virginia, the temperature is not too low. However, it is evident that the fuel efficiency of my vehicle has declined since the change in weather. However, it is rather unfortunate that a Mazda battery may be significantly affected by 40 degree temperatures, resulting in a loss of one-third of its capacity.

markjay Posted April 4 Share Posted April 4 Greetings, everyone. I am new to this platform. We have had our CX90 PHEV for almost one month in the cold climate of Colorado. The following is a description of my experience: Purchased the vehicle, transported it to my residence, and regularly recharge it every evening (scheduled via the application to begin at 10pm according to the local time) using a 110-volt power source. At the beginning, the indicated full charge range was consistently 26 miles, and this remained steady for the first two weeks. The current weather conditions remain same, and the battery will only charge up to a range of 16 miles until it reaches 100% capacity (see to the attached photos). I just noticed this after adjusting the charge time setting to start at 10 pm. I am interested to know whether the battery charge is affected by our driving habits, indicating a potential learning problem. Alternatively, a different option altogether. Any updates or comments on comparable occurrences would be much appreciated. Quote Link to comment Share on other sites More sharing options...
