Safety Features of Custom Built eBike Batteries: Harnessing the Power of Branded Cells, BMS, and Fused Chargers

Ebike batteries have understandably been a topic of discussion in recent weeks, particularly concerning their safety. As eBikes gain traction worldwide due to their eco-friendly and cost-effective nature, understanding the safety features implemented in the design and manufacturing of our batteries becomes critical. In this regard, our company only use branded cells from reputed companies Samsung, Panasonic, and LG; each battery contains a Battery Management System (BMS) with a temperature sensor; and we only provide customers with fused chargers to ensure safety.
Here’s how:

1. We Only Use Branded Cells: Samsung, Panasonic, LG

The heart of any eBike battery is its cells. The quality of these cells significantly influences the performance, longevity, and most importantly, the safety of the battery. This is why we only use branded cells from leading global companies Samsung, Panasonic, and LG.

These brands have a long-standing reputation for producing high-quality, reliable battery cells that have undergone rigorous testing for safety and performance. By opting for these branded cells, we can ensure that the battery packs in our eBikes are not only efficient and long-lasting but also safe.

These cells are designed to offer built-in safety measures, such as venting mechanisms and thermal separators, to prevent overheating or catastrophic failure. They also use chemistries that are intrinsically safer, such as lithium iron phosphate (LiFePO4), which have lower risk of thermal runaway.

2. Incorporated Battery Management System (BMS) with Temperature Sensor

A Battery Management System (BMS) is an essential component of any eBike battery. The BMS controls the charging and discharging of the battery cells, maintaining their health, and prolonging their lifespan. Moreover, the BMS is designed to shut off the battery if any cells are overcharged or overheated, preventing any potential fire risks.

Adding to this, our BMS is equipped with a temperature sensor that continuously monitors the battery’s temperature. This feature is crucial for preventing overheating, one of the most common causes of lithium-ion battery failure. If the sensor detects a temperature that surpasses the safety threshold, the BMS immediately disconnects the battery to prevent any damage or risk of fire.

3. Using Fused Chargers

Fused chargers play a significant role in battery safety. A fuse is a simple device designed to interrupt the flow of high current, thereby protecting the battery pack from potential electrical faults.

Our eBike batteries come with fused chargers, ensuring that the charging process is both efficient and safe. If a fault or an overload is detected during charging, the fuse will blow to stop the current flow, thereby safeguarding the battery and the charger from damage. This makes fused chargers a fail-safe against short circuits or current overload that could otherwise compromise the safety of the battery.

In conclusion, the safety of our eBike batteries is a result of meticulous design and manufacturing processes, coupled with the use of high-quality branded cells, a smart Battery Management System with a temperature sensor, and fused chargers. With these robust safety measures in place, riders can experience the benefits of eBikes with peace of mind, knowing that they are using some of the safest batteries on the market.

We would recommend charging your battery in a shed or workshop. If you do charge your battery inside your home, never leave it charging unattended or overnight.
