Safe. Lithium batteries are not as easy to explode as you imagine. Nowadays, lithium batteries produced by common manufacturers are relatively safe. Most causes of explosions are due to improper operation. Indiscriminate use of chargers Batteries have their own dedicated chargers. If you use a lead acid battery charger to charge a lithium battery, it will easily explode because the voltages of the two are different. If overcharged or overdischarged lithium batteries are used indiscriminately with other electrical appliances, because the electrical power of each electrical appliance is different and the discharge current limit in the lithium battery is also different, some are large and others small, misuse can therefore lead to explosions. Short circuit: If the solder joints of the lithium battery are not firm hangsBefore the production process, long-term use will cause desoldering, which may lead to short circuit and explosion. Emma Electric Vehicle is a brand of Emma Technology Group Co., Ltd., which engages in the R&D and manufacturing of electric bicycles, electric motorcycles, electric mopeds and electric tricycles.
Which is better, a motorcycle lithium battery or a lead acid battery?
I can say this responsibly, no. First of all, electric bike batteries are usually 36V or 48V. The nominal voltage of lithium-ion batteries is 3.7V, so you need at least 10 batteries in series. If your electric car is 48V (determined by the motor), you need 12 batteries in series. Second, the safety of lithium-ion batteries must be guaranteed. Lithium-ion batteries are subject to overcharging, over-discharging, over-current and short-circuitircuits. For example, in the event of overcurrent, when starting an electric vehicle, the current can instantly reach 20 to 30 amps. If the battery you assemble yourself does not have a protection circuit, the battery will easily swell, catch fire or even explode. I'm certainly not trying to scare you when I was experimenting in the company with batteries. the protection circuits would also catch fire. Third, the capacity of the battery connected in series is determined by the capacity of the smallest battery. Your single battery is 4 Ah, but if 10 batteries are connected in series it will still be 4 Ah. Your car almost won't be able to do it. run. Therefore, you either choose a single battery with larger capacity or adopt a series-parallel combination. Of course, in this case, the protection circuit will be more complicated, involving problems tetechnical features such as multi-chain protection and balancing. Anyway, in a word, your idea is not very practical, so don't worry about it.
Is the electric bike battery better, lead acid battery or lithium battery?
Do you worry about the battery as soon as you choose it? Comparison of the advantages and disadvantages of lead-acid batteries and lithium batteries.
Advantages of lead acid batteries:
1. Good safety performance. Lead-acid batteries are easy to maintain. You can knock them over, fix them a little and continue to use them.
2. Cheap price. The price of lead-acid batteries is about 1/3 that of lithium-ion batteries, which shows how low the price is.
3. Recyclable reverse repair. Lead acid batteries are highly recyclable. Once worn out, you can go to an electric car store to exchange them for new ones.velles. You can exchange them for a new set of batteries by paying the price difference, thus minimizing losses. a great advantage for users. Battery lead can also be recycled and reused, reducing environmental pollution.
Disadvantages of lead-acid batteries: high weight, limited battery capacity and short lifespan. Lead-acid batteries typically have a lifespan of around three years with 400 deep charges and discharges.
Advantages of lithium-ion batteries:
1: Lightweight and small size. The volume of lithium-ion battery is 2/3 of the volume of lead-acid battery, and the weight is about 1/3 of the weight of lead-acid battery. Lithium-ion batteries of the same volume have a higher capacity than lead-acid batteries. The reduced weight makes electric vehicles lighter and their range is increased by around 10%.
2: Long life. The time lengthThe average life of lithium-ion batteries is around 4 years, approximately one year longer than that of lead-acid batteries. It can be charged and discharged more than 500 times. The battery has no memory and is very shock resistant.
3: Resistant to overcharge, good resistance to charge and discharge. At normal temperatures, lithium-ion batteries can be continuously charged for 48 hours without causing expansion, leakage, rupture or other accidents, and the capacity remains above 95%. And with a special charger, it can be charged and discharged quickly.
Disadvantages of lithium-ion batteries:
The production cost of lithium-ion batteries is high, the production equipment is expensive, and the labor costs represent approximately 40% of the production cost. The price is about three times that of lead-acid batteries. At three times the price, the value for money is not high, and it seemsrather flashy. Additionally, lithium-ion batteries are not recyclable. Once worn out, they can only be thrown away or buried after thousands of times. years, future generations will not be able to use them. If you dig it up, it will be an antique.
In summary: Generally speaking, lead acid batteries are more cost effective than lithium batteries! Of course, you can choose to use lead-acid batteries or lithium batteries according to your actual needs.
Depending on the quality of the battery products, after-service sale and price, we recommend some good lead acid batteries. Batteries Acid battery brands: Changxin battery, Shinhwa battery, Mantingfang battery.
Lithium batteries and lead-acid batteries are currently commonly used battery types for electric bicycles. They each have their own advantages anddisadvantages. user needs.
Advantages of lithium batteries: Lithium batteries have smaller size, lighter weight, higher energy density, longer life, higher performance, higher security and better usability. Lithium batteries can use fewer battery packs, smaller size, lower cost, less maintenance, higher reliability and higher feasibility.
Advantages of lead acid batteries: 1. Lead acid batteries are relatively cheap, inexpensive and much cheaper than lithium batteries. 2. Lead-acid batteries have good thermal stability and can withstand temperature changes and maintain good performance even at high temperatures.
