The reasons why it is not recommended to use lithium batteries for electric tricycles include poor safety, high temperature flammability, large battery capacity, poor dissipation thermal and poor charging efficiency.
1. Bad security. Lithium battery packs have high specific energy and are an important development direction for lithium battery packs in the future. However, due to their late start, they cannot better guarantee safety when using the vehicle.
2. It is flammable at high temperatures. Lithium batteries begin to decompose at around 200°C. Under the action of high temperature, oxygen molecules are released and the combustion of the electrolyte is activated. The requirements for the charging environment are therefore more stringent.
3. The capacity of theThe battery is large and the heat dissipation is poor. The large capacity of bus batteries increases the risks associated with lithium batteries. When charging for a long time at high temperatures, the heat dissipation performance of the battery will be poor, resulting in the risk of fire or explosion.
4. Poor charging efficiency. Lithium batteries are much worse than lead acid batteries in terms of charging and discharging. This is a major symptom of the inability to effectively use lithium batteries in today's high-powered vehicles, leading to a decrease in their durability.
Precautions for charging electric tricycles
You must use the on-board configuration and designated special charger to charge, otherwise the battery will be damaged or even cause a fire and other hazards. Disconnect the battery first: when charging, you must firstrd disconnect the battery power switch. The electric vehicle should be placed in a well-ventilated, dry, waterproof and waterproof place. Do not cover the charger and battery with anything to avoid the risk of overheating.
Do not place it near flammable or explosive objects to avoid fire, and the loading place should be kept out of reach of children. Due to the phenomenon of battery self-discharge during storage and transportation, the capacity may be insufficient after first use. However, it can reach its normal capacity after two uses after charging.
What temperature can a ternary lithium battery withstand?
General mobile phone lithium batteries have a temperature limit of 40 degrees Celsius, 40-60 degrees. Celsius, if the time is not too long, there will be no problem. Lithium batteries canalso be specially customized to withstand high temperatures, and their high temperature performance will be much better.
The temperature limit set for cell phone lithium batteries is generally 40 to 60 degrees. Batteries are generally marked with explosion-proof valves, and high temperature resistant lithium batteries can withstand temperatures of up to 800 degrees. Generally, lithium batteries are tested to withstand high temperatures of 200 degrees, 500 degrees and 800 degrees, but they are generally not exposed to such high temperatures in daily life.
For lithium batteries, there is currently no clear theory in the industry to support the inevitable relationship between internal resistance, discharge platform, life, capacity, etc. under various temperature performance. The formulascalculations and relevant mathematical models. are still under study. Generally speaking, lithium batteries are not sensitive to temperatures between 0 and 40°C. However, once the temperature exceeds this range, the lifespan and capacity will be compromised.
Detailed information:
1. First of all, there is no obvious ability. Batteries that do not have a clearly marked capacity (1000 mAh or 1000 mAh hours) may contain lower quality or recycled batteries. Many inexpensive batteries on the market are made from recycled batteries. Although these batteries are cheap, they have a short lifespan and unstable quality.
2. Standby time is not guaranteed. Standby time refers to the duration of continuous use between battery installationinto the phone and the next charge. Generally speaking, the batteries sold in the market cannot guarantee standby time to customers because the battery quality is unstable. Many cheap batteries use poor quality battery cores, so the standby time is very short.
3. Whether a safety protection circuit board is installed. Without a protected circuit board, lithium batteries risk deforming, leaking and exploding. The market is flooded with exploding lithium-ion batteries, with companies seeking cheaper protective panels or abandoning them in the face of price competition. Consumers cannot discern the protection of the panel from its appearance.
Reference materials:
40-60 degrees Celsius.
According to the official Pacific Automoti websiteve, we learned that the temperature resistance of ternary lithium batteries is 40 to 60 degrees Celsius. Ternary lithium batteries have the characteristics of high energy density, long cycle life and excellent low temperature performance.
