  • At higher temperature the capacity will be reduced and constant exposure will cause increasing capacity fade.
  • At lower temperature the impedance will be higher reducing efficiency of charging and discharging.
  • The BMS will protect the system from short term over temperature and low temperature operations but the installation must keep the batteries within the recommended temperature.
  • Battery for AGV
