Bora uses 12V60AH batteries, depending on the brand:
1 The price ranges from around €340 to €450 based on recycled batteries from the auto parts market;
2. In 4S stores, the price is about 600-800;
There are currently two types of car batteries, one is the traditional lead-acid battery, which is divided into charged lead-acid batteries dry and in maintenance. free lead acid batteries. The general manufacturer of this type of battery promises a lifespan of more than 2 years. Depending on individual differences and usage conditions, it is normal for the battery life to be between 2 and 8 years.
There is also a new type of wound lead acid battery. The characteristics of this type of battery are smaller size, larger starting current, better resistance to low temperatures and resistance to over-discharge. For example, Bora used toOriginally a 60 Ah battery, and a winding battery of around 35 Ah can meet the requirements. However, the price of wound batteries is 3-4 times that of traditional lead-acid batteries, and since they are relatively new, their lifespan has not yet been verified.
There are many reasons, the main ones are:
1. The safety of lithium batteries, due to the impact of the past explosion of lithium batteries. incidents, Its residents are skeptical about the safety of lithium batteries.
2. The price is half that of an electric vehicle with a lithium battery (the one with a longer range is higher).
3. It is convenient. People already have many tools for short-distance travel, including shared bikes.
The “lithium battery” is a type of battery that uses lithium metal or lithium alloym as the negative electrode material and uses a non-aqueous electrolyte solution.
Lithium batteries are generally divided into two categories:
1. Lithium metal batteries generally use manganese dioxide as the positive electrode material and lithium metal or its metal alloy. Negative electrode material, batteries using non-aqueous electrolyte solutions.
2. Lithium-ion batteries. Lithium-ion batteries generally use lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and use non-aqueous electrolytes.
Although the energy density of lithium metal batteries is high, it can theoretically reach 3860 watts/kg. However, because its properties are not stable enough and cannot be recharged, it cannot be used as a power bank for a usrepeated age. Lithium-ion batteries are being developed as primary power batteries due to their ability to be charged repeatedly. However, due to the combination of different elements, the performance of cathode materials varies greatly in various aspects, which has led to an increase in disputes on the choice of cathode materials in the industry.
Notes on lithium batteries:
Storage requirements: in an environment with a temperature of 20 ± 5℃ and humidity not exceeding 50%, air and water vapor should be avoided. during erosion transport.
This product is divided into two types, A and B. The main characteristics of each are: the appearance of type A is black, the conventional coating thickness is 4-8μm on both sides and the conductive performance is more remarkable; the appearance of type B is light gray and the coating thicknessconventionally is 2-3 µm on both sides. Fewer welding layers can be done in the cladding area and the cladding machine can identify skip gaps.
Type B Carbon Coated Aluminum Box (Gray) Direct ultrasonic welding in the coating area is only suitable for welding laminated battery tabs (maximum 2-3 layers of pole pieces), but ultrasound power and time require fine tuning.
The heat dissipation of carbon layer is worse than that of aluminum foil, so the belt speed and baking temperature should be adjusted appropriately when coating.
