What do I need to pay attention to when I change the battery of my e-bike?

Ensure that the battery size is the same as the original size, and also the voltage needs to be the same, the capacity is not required.

How to choose lithium battery for electric bicycle?

Temperature: Li-ion ternary batteries can retain about 70% of their capacity in winter temperatures of -20℃, and LFP batteries can retain about 50% of their capacity, so choosing a Li-ion battery pack that can resist low temperatures is one of the issues you need to consider

Endurance: Choosing a high-capacity Li-ion battery pack can help owners have a longer range.

Safety: Lithium batteries are not at risk of spontaneous combustion and explosion due to high temperatures.

Maintenance: Both LFP, NMC, and LTO batteries do not require maintenance.

Energy Density: In the same volume, NMC > LFP energy density.

Do bicycle batteries need to be fully discharged before charging?
  1. lithium batteries, generally shallow charging, and discharging is best, in the amount of 20% -90% of the most use between the best, charging do not charge too full, discharge should not be discharged completely, such as the amount of power in about 20% need to be charged, 90% or so can not be charged.
  2. lead-acid bicycle, general remaining power between 20%-60% charging, the most friendly to the battery.
How many types of e-bike batteries are there?

Lead-acid battery
18650 lithium battery pack
Soft-pack lithium polymer batteries
Lithium iron phosphate battery

What kind of battery is good for electric bicycle?

Lead-acid batteries
Pros:

  1. high safety
  2. low cost
  3. recyclable

Cons:

  1. large, bulky
  2. Short life span
  3. low energy density

Lithium batteries
Pros:

  1. high energy density
  2. long life
  3. lightweight

Cons:

  1. safety performance needs to be improved
  2. high cost, expensive

 

Lithium battery is divided into: lithium ternary, lithium iron phosphate, lithium manganate

Safety performance: lithium phosphate > lithium manganate > lithium ternary
Energy density: lithium ternary > lithium manganate > lithium phosphate
Lithium ternary battery: the main cathode materials are: nickel, cobalt, and manganese, of which cobalt metal is expensive, mainly relying on imports, resulting in the cost of lithium ternary battery is not controllable.
Lithium phosphate battery: the advantages are high safety, high-temperature resistance, and long cycle life; disadvantages Due to the high cost of materials in the manufacturing cost, and the low rate of finished products, resulting in higher final price, the price of lithium manganese acid battery: the price of lithium manganese acid battery: the price is very high.
Lithium manganate battery: cheaper, energy density, low-temperature performance are good; disadvantages of poor cycle life, in high temperatures, sun exposure is easy to decline.

How to maintain e-bike battery?

Reasonable charging: Overcharging will cause the battery to swell, and riding will be affected if the battery is not fully charged. Choose a standard charger and try to use the original factory charger.

Dry Charging Environment: The battery box needs to be kept in a clean and ventilated environment. Debris in the battery box may wear out the battery or even wear it out. The battery box should be kept ventilated and not used in a closed environment to prevent the battery from generating gases that may accumulate and cause accidents.

Regular maintenance: All equipment requires maintenance, and the batteries should be visually inspected every three months.

How to choose 18650 cells for lithium batteries for electric bicycles?

First of all, you need to ensure that the supplier of the battery cell produces a qualified cell so that no safety accidents will occur, and then by ensuring that the battery voltage, internal resistance, and capacity of the three indicators can not be too big a difference.

Why don't e-bikes use high voltage batteries?

In consideration of safety: High-voltage battery cells and batteries, whether in use or charging will produce high voltage, if not standardized use of short-circuit prone to fire, explosion, and other dangers, so the bike usually uses low-voltage battery cells.

Cost factor: High-voltage batteries require a high level of production requirements, and more stringent requirements for production and raw materials, which makes the cost of high-voltage batteries higher, while the use of low-voltage batteries can better control the cost.

Range Requirement: E-bikes are usually used for commuting to work, which requires a lower range and makes low-voltage batteries able to meet this feature.

Charging Facility Limitations: High-voltage batteries usually require more complex management systems and higher requirements for charging facilities. Since charging is usually done at home or outdoors, low-voltage batteries are not dangerous.

Can I directly replace the lithium battery of an e-bike with a sodium battery of equal capacity?

First of all lithium batteries can be replaced with sodium batteries, but you need to make sure that the battery voltage and capacity are the same as those of the lithium batteries, at the same time sodium batteries charge faster, and it is better to be able to slightly improve the wiring. Note: Sodium batteries are heavier and may involve reinforcing the frame.

Four things you can't do with lithium e-bike batteries:

Regular charging: e-bike batteries also self-discharge when not in use It is recommended that the battery be recharged in 1 month and stored at about 50%.
Can not charge all night: the charger does not have an automatic power-off function, if charging for a long time will cause overcharging, affecting the battery life, there may be fire and other dangers.
Need to use a matching charger: if the charger is not matched, then the damage to the battery is irreversible.
Can’t charge immediately after riding: At the end of riding, the battery generates heat due to discharge, if charging immediately, then the heat generated by charging and the heat of riding will be added together, which will affect the battery’s range and life.
Cannot charge in a high-temperature environment: High temperature will cause the battery to “overheat”, which will easily cause the battery to bulge, leading to dangerous accidents.

What certifications are required for e-bike batteries?

CQC (products meet relevant quality, safety, performance, EMC, and other certification requirements)、EN 15194:2017、UN38.3、UN-package、FCC、CB、ROHS.
