| Abstract: |
| Objective To solve the discharging capacity decrease on the battery of medium duty vehicle & heavy duty vehicle in plateau and severe cold area. Methods The vehicle lead acid battery was heated with a fuel-fired air heater and insulated with a special warm-box. The internal temperature of the battery was kept in the normal range to guarantee the discharge capacity of the battery at low temperature. Results The temperature of electrolyte in lead acid battery could be raised to normal temperature with heater and warm-box. The discharge capacity could be improved by about 65% at -25 ℃ and 110% at -41 ℃. Conclusion In low temperature environment, the battery heater and warm-box can effectively improve the charge and discharge capacity of battery and supply enough electricity for engine starting and the auxiliary devices, which can provide effective protection for the engine's starting and running in plateau and cold area.. |
