eBike Battery Safety: Everything You Need to Know

It’s no joke that eBikes have truly taken a storm in today's modern society. Becoming a powerful use of transportation and an environmentally friendly one at that. But, the average Joe may lack the knowledge in terms of the technical side of things, leaving questions about what they need to know about an eBike battery and the safety measures involved. This article provides those informational goodies you seek.




Tech time! What's Inside An eBike Battery?

eBike battery packs consist of rechargeable cells, where a lithium compound or electrolyte is positioned between the anode and the cathode. The electrolyte facilitates the movement of electrons or ions from the charging port (anode) to the cathode, enabling the flow of electrical energy within the battery.

eBike batteries also have a Battery Management System (BMS). This is in an electric bike which is a crucial component responsible for monitoring, controlling, and protecting the battery pack. Electric bikes typically use lithium-ion or lithium-polymer batteries, and the BMS ensures the safe and efficient operation of these batteries throughout their lifespan.

You’re probably thinking, “Great! The battery has its own component to manage the battery pack which means less work for me!”. But, it is important to understand how to look after your eBike battery pack as it is ultimately up to you to ensure the uttermost safe practices when charging and looking after your eBike battery pack. Any form of neglect towards your battery pack could result in fatal consequences, such as the battery pack overheating and exploding thus creating a fire that could result in a potential house fire or any form of fire that is. In order to ensure, this isn’t the case, we have put together a comprehensive list of essential tips when looking after an eBike battery pack that you will find very helpful.
