No. This is one of the oldest tricks in the book.
When I worked for BMW North America, I was in charge of battery field service. I took a trip to the Deta Douglas battery plant, manufacturing BMW branded batteries in the US, to be used in place of "BMW" Varta from Europe. There are very few actual battery plants left, as working with lead and acid is never a first career choice...
The difference between Diehard Silver and Diehard Gold? (which were made by either Johnson Controls (aka Interstate) or Exide) . . .
Nothing. Well, one thing... the Price!
The battery construction and chemistry are the same. The stickers and decorations are fancier. The price is higher, but the warranty is extended. Instead of 12 replaced and 24 more prorated, you might see 18 months replaced and 42 more prorated.
There are no OEMs that make their own batteries, at least that I know of. They get somebody else to do it (Johnson Controls, Douglass, Exide) with their own colors and branding.
With a dealer branded battery, price is liable to be three times as much, with a warranty more limited than a quality (I'm fond of Instersate) "aftermarket" battery. In fact, OEMs are looking to sell a car, not give you a 5-year battery. Battery aftersales have a different agenda.
Only in cases of extremely odd battery shapes and capacities would I consider dealer replacement.
Are you considering the switch to electric vehicles but have questions about MG battery technology? You're not alone. As the world shifts towards cleaner and more sustainable transportation options, understanding the ins and outs of MG battery FAQs is essential. In this informative blog post, we aim to demystify the most common questions and concerns surrounding MG battery technology.
How do MG electric vehicles regulate traction battery temperature?
Lithium-Ion batteries in MG cars have liquid cooling and heating to ensure the cell temperature is optimal at all times.
Why should I trust the traction battery in my MG electric vehicle?
Battery manufacturing is to the highest standard and, combined with extensive testing, helps to provide the safest product possible.
What protects the traction battery in my MG electric vehicle?
The battery pack casing is made to a very high strength to ensure maximum impact resistance.
Are electric vehicle batteries safe to use and drive with?
Yes, EV batteries are designed with safety in mind and undergo rigorous testing to ensure they are safe for everyday use.
What is the new battery technology in the MG4?
The new MG4 battery technology includes an innovative cell adaptive pressure control system. Additionally, MG4 uses a new horizontal cell design. This results in a fast charging, industry-leading, 110mm ultra-thin battery pack that gives a completely flat battery with no protrusions. (110mm is less than the height of a soft drink can - 123mm - and less than a Tesla Model 3 battery at 122mm).
What tests is the MG4 battery subject to?
There are six different tests, consisting of water wading, temperature, needle penetration, durability, decay cycle and a special in-house test.
Does the battery undergo extreme environment testing?
Yes, there are eight tests, and these include EV range, charging efficiency, door lock freezing, snow cover, air-con heating, defrosting and defogging, low-friction road and a pan-European road test.
How does the slim and flat ‘one-pack’ battery in the MG4 help provide thermal runaway protection?
The horizontal cell design and the physical separation of the cells (by means of the cooling system and heat shields) effectively limits the spread of thermal runaway to adjacent cells.
How is battery cooling achieved?
The battery cooling system uses vertical water-cooling channels to improve heat dissipation efficiency.
What are the main safety features of electric vehicle batteries?
EV batteries incorporate various safety features, including thermal management systems, voltage monitoring, and protective enclosures to prevent overcharging, overheating, and over-discharging.
How do manufacturers ensure the safety of EV batteries?
Manufacturers use advanced materials, thorough testing, and quality control procedures during production to ensure the safety of EV batteries. They also implement safety measures such as battery management systems (BMS) and thermal management systems.
What should I do if I'm involved in an accident in my electric vehicle?
If you're in an accident, follow standard safety procedures, such as exiting the vehicle if it's safe to do so. EV batteries are designed to withstand impact, but it's essential to contact emergency services and follow their guidance.
How should I store my electric vehicle to ensure battery safety?
If you need to store your EV for an extended period, keep it in a cool, dry place with a partial charge (around 50%). Modern EVs have battery management systems that help protect the battery during storage.
Can I charge my electric vehicle in extreme weather conditions?
Most EVs can be charged in various weather conditions. However, extreme temperatures (very hot or very cold) can affect charging speed and battery performance. It's essential to follow manufacturer guidelines.
Are there any precautions when using public charging stations?
When using public charging stations, ensure you're using a reputable station, and follow the recommended charging protocols. Always use charging cables and connectors that are in good condition.
What is ‘thermal runaway’ and how is it prevented?
Thermal runaway is a condition where the temperature of the battery increases uncontrollably. EVs have cooling systems and thermal management systems to prevent and mitigate thermal runaway.
Can I modify or repair my electric vehicle battery myself?
Modifying or repairing an EV battery yourself is highly discouraged. It's recommended to seek professional assistance from trained technicians or authorised service centres for any battery-related issues.
Are there any safety recalls for EV batteries?
Like any other automotive component, EV batteries may be subject to recalls if safety concerns arise. Stay informed about recalls and address them promptly through authorised service centres.
What is the expected lifespan of an electric vehicle battery?
The lifespan of an EV battery varies depending on factors like usage, environmental conditions, and the specific battery chemistry. Most EV manufacturers provide warranties on their batteries, often covering a certain number of years or miles.
Are there disposal or recycling considerations for EV batteries?
Yes, EV batteries must be properly disposed of or recycled at the end of their life cycle. Many manufacturers and third-party organisations have recycling programs in place to ensure responsible disposal.
The shift towards electric mobility has never been more apparent, and MG battery technology plays a vital role in this movement. We hope that armed with this information, you have a clearer understanding of the benefits and considerations involved in owning an MG battery-powered vehicle.
