  • This invention relates to a battery temperature regulating system and method. More particularly, but not exclusively, this invention relates to a battery temperature regulating system and method which regulates the temperature of a battery to optimize its performance and/or increase its lifespan.
  • Batteries are well-known and widely used to convert stored chemical energy into electrical energy which can be used as a source of power, when required.
  • the lifespan and performance of batteries are affected by the temperature which they are exposed to. This is especially a problem for batteries being used at remote locations when they could be exposed to adverse weather conditions. For example, when batteries are exposed to adverse temperatures on a regular basis or for a prolonged period, their lifespan generally reduces. Similarly, the performance of batteries diminishes if they are exposed to adverse temperatures, especially to low temperatures. The more extreme the temperature, being either high or low, the greater impact it has on the lifespan and performance.
  • a system depends, as a source of power on a battery (or a battery bank) having a particular performance rating, the power supply to the system could become inadequate when the battery is exposed to adverse temperatures.
