From the perspective of environmental protection, the pollution of lead-acid batteries can not be avoided. Lead plate and sulfuric acid solution of the lead-acid battery are difficult to degrade. The safety of lead-acid batteries and the reduction of range caused by battery attenuation are also a headache for the court. Taking a double-seat golf cart as an example, the common golf cart on the market is equipped with 6 175Ah lead-acid batteries. The mileage of new vehicles equipped with such batteries is about 40km after being fully charged. However, with the increase of the service time of the golf cart, the charging and discharging capacity of the battery will be worse and worse, even less than 10km. The decrease in the range of the service life will greatly affect the normal use of the golf cart. These problems in lead-acid batteries can not be solved from the technical point of view, but things have changed after the emergence of lithium batteries. It is inevitable to replace lead-acid power batteries with lithium batteries. We share some knowledge and give a brief introduction to the advantages of lithium batteries used in golf carts below.
