The most efficient batteries recognized by deliverymen: graphene batteries and lithium ion for cars.
1. Graphene battery
Graphene batteries, like lead-acid batteries, are made of graphite, which can reduce internal resistance, improve conductivity, and increase capacity. The main products are 60V24Ah, 60V32ah, 72V23ah and 72V35ah. High-quality graphite batteries can be reused 700 to 1,000 times.
The reason is obvious. A 72V35Ah graphene battery can reach 200km on a single charge, while a courier can travel 100km a day, 2 days and 2 weeks, and can absorb 170 times a year, while the battery life cycle is 1000 times, that is to say, after 5 years and 8 years, the service life of the battery will reach 5.8 years. Of course, this is under the condition of no power outage and normal operation.
2. Automotive lithium ion
The so-called "automotive use" refers to one cycle, which takes about 1,500 cycles. Lithium iron phosphate is the leading product. Low-speed electric vehicles use aluminum casings, plastic casings, or 60V32ah cylindrical electric cores. Choose 60V32Ah or higher power automotive lithium ion, such as 72V32Ah, 60V50Ah (3Wh), and travel 200km. Fifteen hundred cycles, if it is once every two days, it can be used 160 times a year, and a set of batteries will last more than nine years.
Precautions for charging battery cars
1. Do not place the battery car charger in a humid place, otherwise the charger will be damaged. If it is not used for a long time, it is best to take out the battery and store it. Because batteries are prone to aging in low-temperature environments and prone to explosion and fire in high-temperature environments.
2. Do not use high-power electrical appliances (such as air conditioners, electric stoves, etc.) for a long time when charging the battery car to avoid overloading the circuit and causing a fire; do not plug or unplug the charger plug with wet hands to prevent an accident. Risk of electric shock; also be careful not to let children touch or operate power switches, sockets and other equipment; do not charge near flammable items.
3. Battery vehicles and electric vehicles should be stored separately and avoid direct sunlight and exposure; the life of the battery is generally between 2-3 years, so it is recommended to replace the battery with a new one or perform maintenance work regularly (generally every Check once every six months); pay attention to prevent electrolyte from leaking into the electric vehicle and causing short circuit failure.
