How does an EV battery work?

Electric vehicle (EV) batteries are intricate energy storage systems that fuel the vehicle’s electric motor. They consist of battery cells organised into modules, managed by a sophisticated battery management system (BMS) to ensure efficient operation.

Battery cells, available in various shapes like cylindrical, prismatic, or pouch-shaped, serve as the primary storage units for electrical energy. They store and release energy as needed through chemical reactions, powering the vehicle’s electric motor.

The battery management system (BMS) plays a crucial role in overseeing the battery pack’s performance, regulating temperature, voltage, and state of charge. This management ensures optimal operation, preventing issues like overcharging or overheating and facilitating cell balancing for uniform performance.

What is the process to repair an EV battery?

When addressing an electric vehicle (EV) battery issue, repairs often involve diagnosing and resolving specific issues within the battery modules. These issues can arise from various factors such as cell degradation or environmental conditions like temperature variations. In this particular instance, the repair focused on replacing a module that had developed issues affecting its performance and reliability.

Supervised by a staff member from JLR NZ, Alex, our skilled technician at Archibalds, led the repair process with care and expertise. Here’s a closer look at how the repair was carried out:

  • Preparation: Before beginning the repair, Alex ensured the battery pack was safely powered off and removed any protective covers or enclosures to access the internal components.
  • Isolation: Through comprehensive testing and analysis, Alex identified the specific module requiring replacement and isolated it from the rest of the battery pack. This involved disconnecting inter-module connections to ensure only the targeted module was affected.
  • Module Replacement: With careful attention, Alex removed the damaged module from the pack and replaced it with a new one, following manufacturer guidelines for proper installation.
  • Reassembly: Once the new module was installed, Alex reassembled the battery pack, reconnecting inter-module connections and replacing protective covers or enclosures. Every component was secured to prevent potential issues.
  • Testing: The repaired battery pack underwent thorough testing to verify its functionality and safety. Alex conducted diagnostic tests to ensure proper voltage levels, cell balancing, and overall performance before returning it to service.

Alex’s Key Battery Tip

Preconditioning in the Morning

Preconditioning is vital for getting the most out of your electric vehicle (EV), especially on those brisk Canterbury mornings. Alex, our experienced technician at Archibalds, can’t stress how crucial it is to keep your battery in tip-top condition.

Think of it as giving your battery a warm-up before it hits the road, particularly important on chilly mornings when cold weather can put a damper on performance and range. Luckily, many EVs come equipped with battery preconditioning features, allowing you to prep the battery pack before setting off.

In the morning, a quick session with the vehicle’s climate control system ensures your battery is at the perfect temperature. This not only boosts efficiency but also guarantees maximum power output, especially when you need that extra zip during acceleration. And let’s not forget, it ensures everyone inside stays nice and cozy.

Starting your day with a bit of battery pampering goes a long way in maximizing your EV’s range and performance, especially in colder climates. This insider tip from Alex truly enhances your ownership experience, ensuring your EV is always ready to perform at its peak in any driving scenario.

In a world of rapidly evolving technology, staying up to date with the latest vehicle advancements is essential. With this inside look at EV batteries, we hope you’ve gained valuable insights into the intricate world of electric vehicles.
