What You Need to Know About E-bike Battery Safety

It’s no secret that here at Liv we’re huge fans of electric bikes. Just the mere mention of our women’s E-bike range breaks us out in a big smile.

But. we’ll also put on our serious face and discuss electric bike battery safety with you. Because we know that E-bikes, with their high-tech batteries, can sometimes feel complex.

That’s why we’ve broken it down in this article. So read on to discover :

  • What’s inside an electric bike battery (the techy stuff)
  • How we ensure the highest battery safety standards on our Liv E-bikes
  • The 13 must-know best practices for ultimate E-bike battery safety

The techy stuff: What’s inside an E-bike battery?

E-bike battery packs consist of individual battery cells containing lithium-ions. These battery cells store the energy to power the motor.

E-bike batteries are made with either cylindrical, prismatic, or pouch-shaped cells. The shape of these cells is really important. High-quality E-bike battery suppliers like Panasonic, Shimano, and Bosch use cylindrical cells because they handle higher temperatures without deforming.

Aside from the individual battery cells, a critical component inside an E-bike battery is the battery management system (BMS).

The BMS is hugely important as it regulates the individual performance of each battery cell. Regulation is important because even when they’re installed at the same time all the individual batteries don’t drain, deteriorate or perform at the same rate. Some cells last longer than others, some cells will drain slower than others and some will glitch out and cause more problems than others.

Left to their own devices, with so many cells acting independently, you’d encounter performance and safety issues with your E-bike.

So the BMS helps to provide your E-bike battery with long-term consistent performance.

We like to think of the BMS as the competent ride leader overseeing a group of different riding abilities and working to keep everyone together on the trails.

How we ensure the highest battery safety standards in our Liv E-bikes

At Liv, we take your safety VERY seriously. That’s why our E-bike batteries have been co-developed in partnership with the biggest and best battery manufacturer available – Panasonic.

Although other brands may purchase Panasonic batteries Liv has gone the extra mile. or two.

Firstly, we work closely with Panasonic to co-develop our batteries. The output is an e-bike battery that’s completely proprietary to us and designed to the highest safety standards.

Secondly, not only does Panasonic manufacture the cells and the battery management system on our E-bikes but they also assemble and test them for us.

So by investing in a Liv E-bike you can feel totally confident you’re getting a safe, reliable, and high-performing battery that’s developed, assembled, and tested by industry leaders. You won’t find our e-bike battery on any other e-bike on the market.

Liv’s EnergyPak E-bike battery is also distinct from other brands because it has individual separators (rooms) inside. This helps prevent heat from spreading from one cell to another.

Our BMS – aka the capable ride leader – monitors the battery pack and individual cells to make sure each cell is regulated for maximum efficiency and to prevent overheating.

e-bike, battery, pack, market, size, share

While your Liv E-bike is charging, Liv’s Smart Charger continuously communicates with the battery to ensure individual cells are charged at the optimum rate. Also, in extremely hot or cold weather conditions the Smart Charger will adjust the charging voltage for optimal battery efficiency.

simple do’s and don’ts for ultimate E-bike battery safety

E-bike battery safety: The Do’s

  • Do purchase your E-bike from a reputable e-bike brand.
  • Do always use the battery and charger that originally came with your E-bike.
  • Do go to an authorized dealer if your battery is damaged so they can check it before your next ride.
  • Do remove your battery when transporting your e-bike to protect it from damage.
  • Do store the battery at room temperature in a moisture-free environment to avoid unnecessary damage to the cells.
  • Do keep the battery away from children and pets.
  • Do stop the charging procedure immediately if you feel concerned.

E-bike battery safety: The Don’ts

  • Don’t modify your E-bike or let your ‘helpful’ friend tinker with it either. For maintenance, always go to an authorized dealer for your E-bike brand.
  • Don’t charge your E-bike around flammable materials.
  • Don’t store your E-bike battery in a damp place.
  • Don’t subject the battery or charger to high-impact eg. by dropping them
  • Don’t cover the battery or charger or place objects on top of it.
  • Don’t leave your battery at full charge if you’re storing it for a month or more. It is also best to remove the battery from the bike and store it at 60% of its capacity. You can make use of Liv’s Smart Charger which has a useful 60% charge function to ensure safe storage.

Now let’s look at the bikes.

OK. Battery tech talk–done. Serious face–gone. Now for the fun stuff because it’s time for you to start drooling over our awesome range of women’s E-bikes.

powerful and cheaper batteries – Not just for Tesla, but for ebikes too?

Elon Musk wants to reduce battery costs by over 50% – that’s one of the key takeaways from the Tesla Battery Day 2020. Given that our beloved ebikes and Teslas alike have all been powered by the same type of battery cells until now, the announcement of the new 4680 cells made us prick up our ears. Will our ebike batteries, and in turn our future ebike purchases, become more affordable and more powerful?

Elon Musk announces a new generation of battery cells

Battery manufacturing costs are high and currently contribute significantly to overall vehicle costs. During the three-hour live broadcast of Tesla’s Annual Shareholder Meeting and Battery Day on YouTube, Elon Musk announced a new generation of cells that will be used in future Teslas and are intended to lower the barrier for entry into electric mobility. We explain how Musk wants to make this reduction in costs possible:

New cell design = 14% cost reduction

Up until now, the battery cells used in our ebikes have been 1865 (also 18650) or 2170 (also 21700) cells, which have a cylindrical shape. The number designates the size of the cell. For example, the 18 refers to the diameter and the 65 to the height, both in mm. The 2170 cells, which have been in commercial use since 2017, as well as the older 1865 cells, are the same as those currently found in Tesla vehicles.

Advantages of the 4680 cell: – 16% more range – 5 x more energy capacity – 6 x more power

The new 4680 cell announced by Elon Musk has a diameter of 46 mm and a height of 80 mm. That makes it significantly larger than traditional battery cells. The new design is to be manufactured at the new Tesla factory in Brandenburg.

The traditional (1865 and 2170) have a tab design, meaning that the electrons powering the circuit have a relatively long path to flow through

The new 4680 Tesla cells use a tabless design, not only shortening the path the electrons have to travel but also consisting of less individual parts, making them easier to manufacture. The cells aren’t yet production ready and Tesla is in the midst of testing them.

New materials in the anode = 5% cost reduction

Integration of the battery into the car chassis = 7% cost reduction

In the future, Tesla want to integrate battery cells as an integral structural element in the base of their cars. That should result in a vehicle weight reduction of 10% with a possible range extension of up to 14%, as well as a reduction in the number of parts.

Conclusion:

We’re convinced that the grandiose announcements of the visionary Elon Musk regarding more powerful and simultaneously cheaper battery cells will become reality. That might also have implications for ebikes – even if there is a bit of a delay. The idea to use the battery as an integral part of the chassis and to reduce vehicle weight, as well as increase range, could easily be a feature of future urban ebikes were it not for the practical issue of removing the battery. The innovations announced in terms of the electrode materials and optimised production methods may even find applications in the traditional 1860 and 2170 cell sizes and improve and reduce their cost. As of yet, it’s unclear whether the new 4680 cells will find use on ebikes due to their size.

Description

The re-celling of a battery of the electric bike saves money and nature! Replacing the new battery cells is a cheaper way to get the wheels rolling again. The battery usually dies in winter because its voltage drops too low (less than 2.5V in the battery).

Batteries for use in electric wheels

In Finland, almost all e-bike batteries use li-ion or li-po battery cells. The advantage of lithium batteries is light weight and high capacity and power supply in relation to the size of the battery. The weakness of lithium batteries is sensitivity to overcharging or undercharging. For example, the battery cell 18650 li-ion, which is the most used battery cell for electric bikes, requires a charge of 2.5V to 4.2V. Therefore, aBMS (Battery Management System) (Battery Management System) has been added to the battery packs.

The function of the BMS is to monitor the cells in the battery pack and to interrupt the discharge or charge when the battery reaches the programmed voltage level. Due to bms, lithium batteries are quite simple because the cyclist does not have to measure the battery charge, but the BMS stops the power supply. Thus, the battery runs out before it reaches dangerously low voltage. So it’s the same as on the phone. The phone reports a battery charge of 0%, but in reality the battery still has power to prevent deep discharge from damaging it.

Probattery tips for maintaining the battery of an electric bike:

  • Do not disassemble the battery too empty! If possible, do not disassemble the battery in less than 20% of the charge. The lithium battery starts to oxidize in too low a charge. Keep the battery in a 60-80% charge, especially when storing. In winter, it is a good idea to charge the battery every three months.
  • If the battery is hot, allow it to cool down before charging. The battery may warm up when discharged with high current. Heat is especially the enemy of the li-po battery. Battery chemistry stays smoother and in good condition for longer if you do not charge the battery when it is hot.
  • Keep the battery close to room temperature. The frosty winter in Finland absorbs the juices from the batteries if the battery is left cold. Similarly, temperatures above 40ºC over time interfere with chemical reactions in the battery. Take the battery in for the winter and in the summer store in the shade.

How long does the e-bike battery last?

The cyclist’s driving style affects the life of the battery. Hard accelerations require more power from the battery. The lithium battery can withstand about 500 recharges. This can be greatly reduced if the battery is constantly discharged with high currents. Some wheels prioritize the range and battery age by limiting the battery output.

Lithium battery performance is always a compromise between capacity and power supply. The maximum capacity of the 18650 battery is practically 3500mAh or 3.5Ah. The maximum power is approximately 35 amps from a battery cell of that size. However, these features can never be obtained in the same battery cell.

A high range is obtained by selecting a high-capacity battery sensor, such as Samsung 35E or LG MJ1. These 18650 batteries offer 3.5 Ah capacity, but the maximum discharge current is only 10 amps. If you want more power off your bike, you can choose between high discharge battery cells such as the Sony VTC5A or Molicell P26. These batteries have only 2.6Ah capacity, but a wild 35A power supply.

Of course, by connecting the batteries in the chest and series, you can get more familiar readings, such as 36V and 418Wh. Well, what do we just talk about amps and now all of a sudden watt lessons?

The Shimano BT-E6000 e-bike battery is powered by 18650 li-ion cells with a rated voltage of 3.6V. It can therefore be calculated that the battery is connected in a series of 10 batteries. 36V / 3,6V = 10.

The amps are obtained by dividing the wattage hours by voltage, i.e. volts. 418Wh / 36V = 11,61 Ah. Then, when it is known that shimano’s battery has 40 cells, 11.61Ah can be divided by four. Four because we already know that there are 10 batteries in a row, so in parallel 10 sticks there are four.

11,61Ah / 4 parallel connections = 2,9 Ah. So we know that the battery uses 40 pcs of 18650 batteries with a capacity of 2900mAh.

This is a good idea to know if you’re wondering which battery cells you’d use to update your e-bike battery.

What should I take into account in the battery of an electric bike?

The e-bike battery package can be built according to the user’s needs using high-capacity cells or high discharge cells. The most common need is to maximize travel, meaning we usually put LG MJ1 18650 cellsto provide 3.5Ah capacity per sensor. Another excellent, slightly cooler option is the Panasonic-Sanyo NCR18650GA 18650 battery cell,3.5Ah capacity and 10A discharge.

The lithium battery possible bms is also the hardest element in the battery. The BMS charge control circuits from the manufacturer have pre-programmed in-control. It involves not only monitoring battery performance, but also discussion sup with the bike management system. For example, the battery tells information about its charge to the bike’s driving computer, which requires much more complex programming. Of course, e-bike manufacturers do not sell separately BMS circuits, but directly from new batteries.

BMS is the biggest challenge for the do-it-yourself construction. The battery pack may keep the battery dead if it has been empty for a long time. Even if the cells are loaded separately back into a good reserve, the programming of BMS cannot usually be changed at home. In this case, you will need to buy a new battery or put in a generic bulkkiBMS that monitors the battery cells, but does not know how to do anything else. Then the electric bike can run on an old battery, but it no longer knows the same tricks as the original.

Do-it-yourself e-bike battery

Only BMS status is an obstacle to those who are handy with their hands. If the BMS is very awake in the battery, but the battery cells are tired, the cells can be replaced.

Here’s a good example for english speakers in the video:

The video makes 13S2P, or 13 cells in series, 2 parallel battery packs. It uses Samsung INR18650-25R 18650 battery cellsthat provide 20A continuous discharge current and 2.5Ah capacity. The parallel connection of two cell lines means 5Ah capacity and 40A discharge current in the battery pack. 13 cells in a stick, i.e. when connected in series, make the battery pack 13x 3.6V = 46 V.

What does it take to get a battery?

When building the battery pack, the battery cells must be as close as possible to each other. In the worst case, if the battery has a high voltage difference, you can build a battery that has not worked.

Connecting the batteries into a battery pack is done by spot welding. Spot welding is practically the only working way, as knocking heats the battery too much and at worst spoils the entire cell.

Spot welding supplies electrical current to the welding site, which provides the heat required by the weld. The result is a very neat welding result and the battery cell remains intact.

Custom-made e-bike battery

If your battery is running out of time, you can also send it to us. We’re analyzing the potential for that condition and re-encapitsion. After the measurements, we agreed with the customer which direction to go with the project. We can order any battery cell from the battery pack, including the new 20700 and 21700 battery cells.

The cost of work consists of battery cells and work done. Depending on the complexity of the battery, the work can cost 150-200 euros. As a result, we’ll send back a battery that probably has better features than original ones. (No need to use the most cheap cells, so you can maximize, for example, the capacity of the battery size within the limits allowed.)

The cells of the e-bike batteries depend a lot on the battery structure and desired features, so please contact us by email info @ proakku.fi
