Abstract
The article presents the results of tests of gel batteries under various operating conditions: in the cold at a temperature not exceeding -7.8 C°, and in the heat at a temperature within 22-24 C°. The results of the study showed an increase in the reduction of vehicle operating time by 33% of the operating time in temperature conditions of 22-24 C°.
Introduction. The article is devoted to the study of the influence of climatic conditions on promising electric transport vehicles used in the tasks of public utilities departments, parks and recreational areas, as well as in indoor warehouses and eco-farms.
Object. Assessment of the actual indicators of the duration of storage of the operating voltage of the battery under conditions of low temperature in comparison with an identical battery under favorable temperature conditions. Tests were carried out both with and without load.
Materials and methods. When studying the operation of gel batteries under various conditions of use, their ability to maintain voltage and electrical capacity was tested. Comparative studies were carried out on the influence of ambient temperature on battery discharge in storage mode and under load. The objects of research were 2 traction gel batteries.
Results and conclusions. The results of tests of gel batteries under various conditions of use are presented: in the cold at a temperature not exceeding -7.8 C° and in the heat at a temperature within 22-24 C°. Their ability to maintain voltage and electrical capacity was tested for compliance with the requirements of operation in electric transport. An assessment of the actual indicators of the duration of storage of the operating voltage of the battery in conditions of low temperature is given in comparison with an identical battery in favorable temperature conditions: a reduction in the operating time of the vehicle by 33% of the operating time under temperature conditions of 22-24 C°.
