Why Choose Lithium Battery in E-rickshaws?
E – rickshaws or Electric rickshaws have been becoming more popular in most parts of the globe since 2008. In India, e – rickshaws began to gain popularity since 2011. As these rickshaws faced a ban by the Indian government in the capital city of Delhi, the increase in their number failed. But, still they are widely used in most parts of the country. On 8 October,2014, the Ministry of Road Transport and Highways had notified the rules to regulate the e- rickshaws by making important amendments under the Motor Vehicles Rules of 1989. In March 2015, the Parliament passed the amendments and finally, legalized the use of electric rickshaws. Recently, the transport department decided to introduce these e-rickshaws in four major cities of Maharashtra – Mumbai, Pune, Nagpur and Nashik. Now, that these new age vehicles will be available on the streets soon, let’s take a look at the advantages and disadvantages of e-rickshaws.
Electric rickshaws (also known as electric tuk-tuks, e-rickshaws, totos and e-tricycles) are small 3-wheeled vehicles powered by an electric motor and battery ranging from 650 to 1400 Watts. They save on fuel costs compared to auto rickshaws while offering greater ease-of-use than pulled rickshaws. This has led to their popularity and widened-acceptance in some cities since 2008. If introduced in a systematic manner, electric rickshaws could be a low-emitter complementary transport for low-income people who suffer most from a lack of transport facility. They are mostly manufactured in India and China.
Why Choose Lithium Battery in E-rickshaws?
Lithium iron phosphate crystal work as the cathode material in lithium battery, we called this kind of battery as LiFePO4 battery. LiFePO4 is one famous kind of lithium battery which is usually work as power battery in new energy vehicles, e-bike, power tools and so on. So, we take LiFePO4 battery as an example to tell you the main seven advantages of lithium battery.
- IMPROVEMENT OF SAFETY PERFORMANCE
The P-O bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and heat up like lithium cobalt oxide or form a strong oxidizing substance, so it has good safety. Some reports pointed out that in actual operation, a small number of samples were found to burn during acupuncture or short-circuit experiments, but there was no explosion. In the experiment, high-voltage charging that greatly exceeded its own discharge voltage several times was used, and it was found that there was still an explosion. Phenomenon. Nevertheless, its overcharge safety has been greatly improved compared with ordinary liquid electrolyte lithium cobalt acid batteries.
- IMPROVEMENT OF LIFE SPAN
The cycle life of long-life lead-acid batteries is about 300 times, the highest is 500 times, while lithium iron phosphate power batteries have a cycle life of more than 2,000 times, and standard charging (5-hour rate) can reach 2,000 times. Lead-acid batteries of the same quality are “new for half a year, old for half a year, and maintenance for half a year”, which takes up to 1 to 1. 5 years, while LiFePO4 battery are used under the same conditions, and the theoretical life span will reach 7 to 8 years. Taking into account the comprehensive considerations, the performance price ratio is theoretically more than 4 times that of lead-acid batteries. High-current discharge can quickly charge and discharge at a high current of 2C. Under a dedicated charger, the battery can be fully charged within 40 minutes of 1. 5C charging, and the starting current can reach 2C, but the lead-acid battery does not have this performance.
- GOOD HIGH-TEMPERATURE PERFORMANCE
The peak electric heating of lithium iron phosphate can reach 350℃-500℃, while lithium manganese acid and lithium cobalt acid are only around 200℃. The operating temperature range is wide (-20℃–75℃), and the peak electric heating of lithium iron phosphate with high temperature resistance can reach 350℃-500℃, while lithium manganese acid and lithium cobalt acid are only around 200℃.
- LARGE CAPACITY
When the battery is often working under the condition of being fully charged and not finished, the capacity will quickly fall below the rated capacity value. This phenomenon is called the memory effect. Like NMH and nickel-cadmium batteries, they have memory properties, but LiFePO4 battery do not have this phenomenon. No matter what state the battery is in, it can be charged and used at will, without having to be recharged first.
- LIGHT WEIGHT
The volume of LiFePO4 battery of the same specification and capacity is 2/3 of the volume of lead-acid batteries and 1/3 of the weight of lead-acid batteries.
- ENVIRONMENT PROTECTION
LiFePO4 battery are generally considered to be free of any heavy metals and rare metals (NMH batteries require rare metals), medium and (SGS certified), and are used in accordance with European RoHS regulations. It is an absolute green battery certificate. Therefore, the reason why lithium batteries are favored by the industry is mainly due to environmental protection considerations. Therefore, the battery has been included in the “863” National High-tech Development Plan during the “Tenth Five-Year Plan” period, and has become a key national project to support and encourage development. With China’s accession to the WTO, China’s exports of electric bicycles will increase rapidly, and electric bicycles entering Europe and the United States have been required to be equipped with pollution-free batteries.
Advantages of e-rickshaws
1. Eco– friendly: E-rickshaws can be the best alternative to petrol or diesel run vehicles as they are operated on battery. These rickshaws do not emit smoke and thus, will not contribute to the increasing air pollution. The batteries which will be used for the functioning of these rickshaws can be effectively recycled and thus, will solve the problem of battery disposal.
2. Economical: E-rickshaws are comparatively cheap and can be easily afforded by a common man. Passengers will have to pay a less transport charge. It is cost effective not only for the consumers but also for the owners. The batteries can be easily recharged from home or from any place that provides a proper voltage.
3. Free from noise pollution: E-rickshaws are free from creating noise pollution as they do not emit any sound. Passengers can have a smooth and comfortable ride.
4. Livelihood: E-rickshaws provide a means of livelihood for the common as well as illiterate people. Without investing much of money, the e-rickshaw drivers can earn a good livelihood.
5. Safety: E-rickshaws involve less risk when compared to the other fuel operating vehicles. They can cause less accident as they are slower and lighter than an auto rickshaw. There is a chance of explosion in the case of fuel operating vehicles.
6. Easy maintenance: As they use electricity, they do not require fuel to operate the engines. E-rickshaws are free from an engine and a gear box and thus, the burden of maintenance is reduced. The motor which is used in these rickshaws is smaller and the battery is placed below it. Hence, maintaining them is quite easier.
