Do you want to ride and enjoy your electric cargo bike when you are taking a leisurely afternoon cruise in the park? To do that, all of your electric cargo bike systems must be working well. One key component is your e-cargo bike batteries. e-cargo bike battery care is vitally important. The battery’s health has a tremendous impact on performance. You want to keep it in good shape, so here are five electric cargo bike battery charging tips meant to help your batteries live a long life.
1. Keep your electric cargo bike battery charged
Lithium batteries are generally best kept fully charged, even after journeys of just a few miles. Completely discharging a lithium battery regularly will significantly reduce its ability to hold a charge, diminishing its capacity. If you can avoid going all the way to zero, your battery will be much happier.
The first 50 percent of a quick charge doesn’t stress the battery much, it’s the last 50 percent that needs to be eased into. While most bikes offer on-the-bike charging, it is good to remove the battery from the bike at least once a month to check the connections. Water, sweat, and general gunk can all potentially cause poor connections and corrosion.
2. Charge your electric cargo bike battery regularly
If you know you will not be using your battery for a few months then it is wise to take some extra precautions: The rate at which a lithium battery self-discharge is highest when fully charged and lowest when almost flat. So over a long time, your battery will lose capacity at least by being partially discharged. However, almost flattening a battery we know is a bad thing to do.
If you’re storing the bike for a few months, a 40 to 70 percent charge is ideal. Check the battery at the beginning of every month. If the battery drops to 20 percent or lower, give it a booster charge to return to the 40 to 70 percent range.
In order to charge your electric bike battery regularly, you need to use it regularly, so let this be another encouragement to get out and ride.
It’s best then to store the battery in the coldest convenient place you can find and then, if possible, give short charges every 5 to 10 weeks.
3. Do not store in extreme temperature
Storage should be done in a dry space between 45 and 85 degrees Fahrenheit. Anything above or below is considered extreme, and not healthy for battery chemistry. This is why it is important not to leave your battery in the car. Even with the ambient temperature being 60 degrees, the inside of your car can exceed these limits in 20 to 30 minutes in direct sunlight. If you can’t take it inside with you, lock it back onto the bike. This will keep it secure and cooler than inside the car.
The lithium powder inside the battery cells decreases its electrical resistance as it warms up. This means that in warmer conditions your battery will discharge more quickly and will need charging more often. You should notice that on cold days your bike will travel less far and this is due to this same property of lithium powder – its resistance increases with colder conditions. This means that you will travel further on warmer days.
While storing batteries in cool conditions is good, always remember to warm the battery to room temperature before charging, charging from frozen can damage the battery.
4. Keep your electric cargo bike battery clean and dry
It is good to remove the battery from the bike at least once a month to check the connections. Water, sweat, and general gunk can all potentially cause poor connections and corrosion. Contacts on the battery should be dried to avoid oxidation and corrosion which would weaken the ability of the battery to power the bike. Check the contacts every few months and clean if necessary. You could use emery cloth if there is any corrosion.
5. Never open an electric cargo bike battery
There is absolutely no point in opening your e-bike’s battery to examine and repair the contents. Opening a lithium battery would be very dangerous! Lithium powder is extremely flammable and will combust on contact with oxygen, explosively! If you suspect your battery is faulty or has lost its capacity you will have to return it for testing and then possible repair.
