E-Bike Battery: Core Energy Source and Common Problem Origin

The ebike battery is the core component that powers the entire bike, and it is also the most expensive and critical part.
Earlier batteries were mostly made from lead-acid, nickel-cadmium, or nickel-metal hydride materials. Modern batteries mainly use lithium-ion technology, making them lighter, more powerful, and longer-lasting.
To ensure battery safety and stability, a Battery Management System (BMS) is also required to prevent issues such as overcharging and deep discharging.

Understanding the basic characteristics of the battery helps in better identifying potential faults and taking appropriate repair measures.

Identifying Common Problems with E-Bike Batteries and Their Causes

E-bike owners often experience battery issues because lithium-ion batteries can explode or catch fire if not handled carefully, including during charging and storage, posing significant safety risks.

Let's discuss the most common problems that can occur when using an e-bike battery:

1. Charging Errors in E-Bike Batteries

  • E-bike battery repair: Various factors can cause reading errors that riders may overlook, leading to significant battery damage.

  • Overcharging: If fully charging the battery takes only 6 hours, it is best to stop charging once the full-charge indicator appears, or at least not charge longer than 7 hours. Overcharging can cause the battery to swell and bulge, resulting in irreparable damage.

  • Damage to the battery core: Charging errors can occur if the battery core is defective.

  • Using incompatible chargers: Many e-bike riders forget to charge their batteries and then use any available charger, which can damage the battery.

2. Rapid Battery Discharge

Rapid battery discharge can be caused by factors such as high usage intensity, damaged battery cells, or improper storage.

3. Battery Overheating

Battery overheating typically starts at temperatures above 45 degrees Celsius. At temperatures exceeding 60 degrees Celsius, serious damage can occur, significantly shortening the battery's lifespan and posing safety risks such as fire or explosion. It is therefore important to operate and store the battery within a temperature range of 20 to 25 degrees Celsius to avoid overheating.

4. Battery Fails to Start the E-Bike

Batteries can discharge due to damage or wear. If not handled carefully, they can deteriorate over time and lose functionality.

How to Identify and Repair E-Bike Batteries

If you want to repair your e-bike battery yourself, you can follow these steps:

  1. Safety first: Before starting the repair, put on protective gloves and safety goggles. Make sure the battery is completely disconnected from the bike and not connected to any power source.

  2. Fault diagnosis: Identify what is wrong with the battery. Common issues include reduced capacity, charging problems, or physical damage. Use a multimeter to check the voltage of each cell and compare the readings with the manufacturer's specifications.

  3. Check the BMS (Battery Management System): Carefully inspect the BMS for visible damage or signs of malfunction. A defective BMS can cause charging and discharging problems. If necessary, the BMS should be reset or replaced.

  4. Replace damaged cells: If some cells are defective or have significantly lower voltage, they must be replaced. Carefully remove the damaged cells and insert new ones with the same specifications.

  5. Balance the battery pack: After replacing cells, it is crucial to balance the battery pack so that all cells have the same voltage. This is essential for battery functionality and longevity.

  6. Reassemble the battery: Once repairs are complete, carefully reassemble the battery housing. Ensure that all connections are secure and that no cables are loose.

  7. Test the battery: Reconnect the battery to the bike and test if everything works correctly. Check if the battery charges properly, delivers the necessary power, and does not overheat.

  8. Observe local regulations: In Germany, there are specific regulations for handling and disposing of batteries. Make sure that all repairs comply with local environmental and safety standards. If in doubt, it is best to consult a professional.

  9. Consider professional repair: If the problem is complex or you are unsure about the repair, it is advisable to use a professional repair service. In Germany, there are many specialized e-bike service centers that handle battery repairs.

  10. Properly dispose of defective components: Dispose of damaged cells or components in accordance with local recycling regulations. In Germany, there are strict rules for battery disposal, so always comply to prevent environmental damage.

The steps described in this guide are for informational purposes only. Always exercise caution when handling batteries and consult a professional if in doubt. Improper handling or repair of batteries can result in serious damage, injury, or fire hazard.
