The maximum charging time of electric bicycles should not exceed 8 hours, and it is strictly forbidden to use temporary power lines, sockets and switches to charge, and it is strictly forbidden to charge in confined spaces or hot sun and high temperature environments. The three group standards of "Technical Specifications for Lithium-ion Power Battery Packs for Electric Bicycles", "Technical Specifications for Chargers for Electric Bicycles" and "Guidelines for the Safe Use of Electric Bicycles" were recently released. The reporter learned that this is the first release of similar standards in the local electric bicycle industry.
How to use?
It is forbidden to install roofs and seats
How to buy, use, park, charge, and maintain electric bicycles? The "Guide to the Safe Use of Electric Bicycles" provides professional guidance for users of electric bicycles.
Some illegal demolition and modification that may lead to safety hazards are explicitly prohibited. The guide proposes that the purchaser should not install and modify the electric bicycle after leaving the factory, and should not replace the power devices such as motors and batteries that do not meet the mandatory certification configuration of the product. In addition, the installation and modification of roofs, carriages, seats and other devices are also prohibited. Acts such as dismantling or altering speed limiting devices are not allowed.
How do I park?
The distance between the gas stations and other parking is more than 5 meters
Electric bicycle parking is also exquisite. According to the requirements of the guidelines, electric bicycles should be parked in open or semi-open special parking places, and should not be parked indoors and at the evacuation passages and safety exits of buildings. Electric bicycles should be parked away from dangerous places such as gas facilities, power distribution facilities, boiler rooms, gas stations, etc., with a spacing of more than 5 meters. It is advisable to park away from the outer wall of the building, and there is no combustible material stacking within 2 meters of the body. Parking in the upper surface of sewage wells, sewers, septic tanks, etc. should be avoided. When the electric bicycle is parked for a long time, the main power supply should be cut off in time and stored in a cool place.
How does the battery charge?
Charging in the hot sun is strictly prohibited
How should the battery be used and maintained correctly? The "Guide to the Safe Use of Electric Bicycles" proposes that the maximum charging time of electric bicycles should not be greater than 8 hours. Before charging, the e-bike should be powered off and the key unplugged.
If the electric bicycle is equipped with a lead-acid battery, if it is stored for a long time, it should be sufficient to charge at least 50% of the electricity, and it should be recharged every other month. If equipped with a lithium battery, if stored for a long time, the power should be kept in the range of 30% to 50%, and a complete charge and discharge cycle should be carried out every other month.
It is strictly forbidden to use methods such as pulling temporary power lines, sockets and switches to charge. Charging in confined spaces or hot sun and high temperature environments is strictly prohibited, and the charger should not be charged in the saddle or tail box.
Lithium batteries should have a fault alarm function
The "Technical Specifications for Lithium-ion Power Battery Packs for Electric Bicycles" proposes that batteries should also be able to collect data, communicate, and fail alarms. Even if the battery is overcharged, overdischarged, externally short-circuited, squeezed, and dropped, the battery pack should also "not fire and not explode"; when subjected to mechanical impact, the battery pack should also "not leak"; in case of water immersion, the battery pack should also not leak, not rupture, not fire, not explosive.
