How many kilometers can a 72-volt battery run?

100 kilometers. The following is an introduction to lithium batteries: 1. Introduction: Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive/negative electrode material and non-aqueous electrolyte solutions. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M.S. Whittingham proposed and began researching lithium-ion batteries. Due to the highly reactive chemical properties of lithium metal, the processing, storage, and use of lithium metal require very high environmental conditions. With the development of science and technology, lithium batteries have become mainstream. 2. Classification: Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and can be recharged. The fifth-generation rechargeable battery, the lithium metal battery, was introduced in 1996, with safety, specific capacity, self-discharge rate, and performance-price ratio all superior to lithium-ion batteries. Due to their high technical requirements, only a few companies in a few countries produce this type of lithium metal battery.
I've been researching electric vehicles for over a decade. The range of a 72-volt battery really depends on specific conditions, with battery capacity and power consumption being the main determining factors. A standard 72-volt battery with 20 ampere-hours capacity stores about 1500 watt-hours of energy when fully charged. Assuming a typical motor power of 200-300 watts, this translates to a range of approximately 50 to 70 kilometers. During my own tests, I found that higher speeds or uphill driving can double the power consumption. For example, at 30 km/h, the range drops to about 40 kilometers. Battery health is also crucial - new batteries can go further, while older ones may only achieve 60% of their original range. Ambient temperature plays a significant role too, with cold weather reducing battery performance and cutting range by over 10%. My general advice is to pay attention to battery specifications when purchasing. For regular models, around 60 kilometers is quite common, but don't expect over 100 kilometers unless equipped with high-capacity batteries and efficient motors.
