MG ZS EV: Common Charging and Battery Problems (+Solutions)

The MG ZS EV is a popular and affordable electric vehicle that has gained a reputation for its impressive range and features.

However, like any EV, it can experience charging problems that can be frustrating for owners.

In this article, we will explore some of the most common charging problems that MG ZS EV owners may encounter and provide possible solutions to these issues.

Problem 1: Charging Stops After a Few Minutes With Smart Charging

The MG ZS EV is not charging for more than 5 minutes at a time, even when connected to different domestic and public chargers.

Several software updates were rolled out by MG to avoid the car from going into sleep mode and causing problems with Smart Charging delay. Regrettably, these updates did not deliver the expected solution for the issue.

Possible solutions: The first thing to check is whether the charging cable is properly plugged in, as it can be a tight fit when new. If the problem persists, try switching off the car completely and then trying again.

If this doesn’t work, try disconnecting the 12V battery for 10 minutes to reboot the system. Another option is to take the car back to the supplier and ask them to show you it charging on their AC charge point and with your domestic charger to rule out any issues with the car itself.

Additionally, it may be worth trying a rapid charger to see if the issue persists. If none of these solutions work, consider contacting MG customer support or getting a software refresh.

Problem 2: Battery Temperature Sensitivity

Electric vehicle batteries are susceptible to temperature-related issues, especially in harsh weather conditions. To ensure optimal performance, it is important to keep the battery within the ideal temperature range of 65 to 115 degrees Fahrenheit (18-45 °C).

Exposure to extremely high or low temperatures may cause the battery to deteriorate and reduce its lifespan.

Possible solution: As an MG ZS EV owner, it is recommended to avoid exposing the battery to excessive heat or cold for extended periods. Additionally, charging or discharging the battery may cause it to heat up, which can indicate a failing or decaying battery pack.

Problem 3: Wrong Battery Level

Another common issue faced by some users of the MG ZS EV is that the battery charge level gets stuck at the level it reached at the end of the last charge.

Possible solutions: Some users report that this issue resolves on its own after a while, while others suggest resetting both trips prior to charging or charging the battery to 100% SOC and allowing the HV battery to carry out a balance cycle.

Sometimes the battery charge level might be sticking at 80% for a while, which might be attributed to charging to the top end of 80% rather than the lower end.

Important: EV battery replacement can cost $1000s. To avoid high-voltage battery replacement, there are some things you can do. Read this article to find out the 10 best ways to maximize EV battery life and save tons of money!

Problem 4: Slow Charging

A common problem of MG ZS EV is a message that keeps coming up on the car’s dashboard saying “Slow Charge Battery.”

Possible solutions: The message is likely due to the battery cells being out of balance, which can happen if the car is rapid charged too often.

The car should be charged to 100% using a 7kW charger, and then leave the charger connected until the MG badge light goes out completely, which should happen once a month according to the car’s manual.

Moreover, the owner should check the full charge battery voltage, which should be between 449/450v or 454/455v.

If the voltage readings a re constantly low this could indicate a problem with the battery and recommend that the owner bring the car to the dealer for a battery status check and a possible BMS reset.

Top Tips to Avoid Battery Problems with the MG ZS EV

  1. Avoid exposing the battery to extreme temperatures.
  2. Charge the battery to 100% SOC and allow for a balance cycle.
  3. Avoid rapid charging too often, which can cause the battery cells to become unbalanced.
  4. Regularly check the battery voltage readings to ensure they are within the normal range.
  5. Perform regular software updates and maintenance checks as recommended by MG.

By following these tips, MG ZS EV owners can avoid common battery problems and ensure their electric vehicle runs smoothly for years to come.


The most common issues include charging stops with smart charging, battery temperature sensitivity, wrong battery level, and slow charging.

Fortunately, there are possible solutions for each of these problems, such as checking the charging cable, avoiding exposing the battery to excessive heat or cold, resetting trips or charging to 100% SOC, and checking the battery voltage.

If these solutions do not work, it is recommended to contact MG customer support or bring the car to the dealer for a battery status check and possible BMS reset.

Overall, understanding these issues and taking preventative measures can help MG ZS EV owners get the most out of their electric vehicle.
