As electric vehicles (EVs) become more popular, BMW has been among the top contenders in the market, offering a range of electric models such as the i3 and iX3. However, one common issue that some BMW EV owners face is the discharging of their car’s batteries, resulting in decreased range and potential inconvenience.
Causes of BMW’s Discharging Batteries
- Parasitic drain: A parasitic drain is an electrical load that draws power from the battery even when the car is not running. This can occur due to a faulty component, such as a malfunctioning module, or if the car is left parked for an extended period without being driven or charged.
- Cold weather: Cold weather can cause a significant decrease in battery performance, particularly for BMW’s lithium-ion batteries. When temperatures drop below freezing, the chemical reactions inside the battery slow down, reducing its capacity and output. Additionally, heating the cabin and other components in cold weather can also drain the battery.
- Battery age: Like all batteries, BMW’s lithium-ion batteries degrade over time and lose their capacity to hold a charge. Depending on the usage, this can occur after several years or sooner.
- Overcharging or undercharging: Overcharging or undercharging can cause permanent damage to the battery cells, reducing their lifespan and capacity.
- High power consumption: Using high power-consuming features such as air conditioning, heating, and entertainment systems can drain the battery faster, particularly if the car is driven at high speeds or in traffic.
Solutions to Discharging Batteries
- Drive the car regularly: Regular driving can help prevent parasitic drains and ensure that the battery stays charged. If you are leaving your car parked for an extended period, consider disconnecting the battery or using a battery maintainer to prevent it from discharging.
- Keep the battery warm: In cold weather, keeping the battery warm can help improve its performance and reduce the risk of discharging. You can do this by parking the car in a garage or using a battery heater.
- Check and replace the battery: If your BMW’s battery is old or showing signs of degradation, consider having it checked or replaced. BMW recommends replacing its batteries every 5 years, although this can vary depending on usage and conditions.
- Charge the battery regularly: Regular charging can help maintain the battery’s capacity and prevent it from discharging. BMW recommends charging their EVs at least once a week, or more frequently if the car is driven less frequently or in cold weather.
- Avoid high power consumption: Using high power-consuming features such as air conditioning, heating, and entertainment systems can drain the battery faster. Consider using these features sparingly or at a lower setting to preserve the battery’s charge.
- Use Eco Pro Mode: BMW’s Eco Pro Mode can help improve the car’s energy efficiency and reduce the drain on the battery. This mode adjusts the car’s power output, throttle response, and climate control to optimize performance and reduce energy consumption.
- Plan your route: Planning your route in advance can help you avoid traffic and reduce the strain on the battery. Additionally, using regenerative braking can help recharge the battery while driving.
BMW’s discharging batteries can be a frustrating issue for EV owners, but with some preventative measures and careful use, it can be mitigated or prevented. Regular driving, charging, and maintenance, as well as using energy-saving features and planning your route, can all help ensure that your BMW’s battery stays charged and ready to go.
