The specific method is as follows. The electric vehicle includes the rechargeable battery 2. The central processing unit above calculates the discharge amount of the charge and discharge battery and performs temperature compensation calculation on the discharge amount of the charge and discharge battery according to the temperature of the charge and discharge battery detected by the temperature detection unit. Quantity, control user prompt unit, such as: battery display unit or battery alarm unit. The discharge amount of the charge-discharge battery after temperature compensation calculation is preferably stored in the storage unit, and can be used as a basis for the charger to use different charging procedures. The temperature compensation calculation method for the discharge capacity of the charging and discharging battery is as follows: If the detected temperature of the charging and discharging battery is 25 degrees Celsius, which is equal to the reference temperature, for example, the remaining power displayed by the power display unit of the electric vehicle is the theoretical remaining power. The remaining power is the difference between the rated capacity of the charge and discharge battery minus the discharge capacity; then if the detected temperature of the charge and discharge battery is greater than the reference temperature, such as 26 degrees Celsius, the remaining power displayed by the power display unit of the electric vehicle is the charge. The difference obtained by subtracting 95% of the discharge capacity from the rated capacity of the discharged battery. At this time, the remaining capacity displayed by the electric vehicle's power display unit is greater than the theoretical remaining capacity; if the detected temperature of the charge and discharge battery is lower than the reference temperature, such as At 24 degrees Celsius, the remaining power displayed by the electric vehicle's power display unit is the difference obtained by subtracting 105% of the discharge capacity from the rated capacity of the charging and discharging battery. The remaining power displayed by the electric vehicle's power display unit is less than the theoretical remaining power. That is to say, if the temperature of the charging and discharging battery is higher than the reference temperature, the discharge amount of the charging and discharging battery will be compensated negatively. The unit displays the remaining power according to the discharge amount information calculated by temperature compensation. In order to achieve the accuracy of the remaining power display or alarm of the rechargeable battery, temperature compensation can also be performed on the remaining power of the rechargeable battery, that is, according to the discharge capacity and rated capacity of the rechargeable battery, the remaining power of the rechargeable and discharged battery is calculated, according to the temperature. The temperature of the rechargeable battery detected by the detection unit performs temperature compensation calculation on the theoretical remaining power of the charging and discharging battery, obtains the actual remaining power calculated by temperature compensation, and controls the power display unit or the power alarm unit according to the actual remaining power calculated by temperature compensation. The actual remaining power of the charging and discharging battery after temperature compensation calculation is best stored in the storage unit, and can be used as a basis for the charger to use different charging procedures. If the detected temperature of the charging and discharging battery is 25 degrees Celsius, which is equal to the reference temperature, for example, the power display unit of the electric vehicle shows that the remaining power is the theoretical remaining power, that is, the difference between the rated capacity and the discharge capacity; When the temperature of the discharged battery is greater than the reference temperature, such as 26 degrees Celsius, the actual remaining power displayed by the electric vehicle's power display unit is 105% of the theoretical remaining power. At this time, the remaining power displayed by the electric vehicle's power display unit is greater than the theoretical remaining power. ; If the detected temperature of the charging and discharging battery is lower than the reference temperature, such as 24 degrees Celsius, the actual remaining power displayed by the electric vehicle's power display unit is 95% of the theoretical remaining power, and the actual remaining power displayed by the electric vehicle's power display unit is If it is less than the theoretical remaining power, that is, the temperature of the charging and discharging battery is higher than the reference temperature, the theoretical remaining power of the charging and discharging battery will be compensated positively. If the temperature is lower than the reference temperature, the theoretical remaining power of the charging and discharging battery will be negatively compensated. Therefore, the user indicating unit of the electric vehicle displays the remaining power according to the actual remaining power information calculated by temperature compensation. In addition to displaying the remaining power, it can also display the remaining riding mileage or remaining riding time. If the user prompting unit on the electric vehicle is set as a power alarm unit, the power alarm unit will alarm based on the discharge amount information calculated by temperature compensation or the actual remaining power information calculated by temperature compensation. Alarm after a certain value or when the actual remaining power calculated by temperature compensation is lower than a certain value, alarm. The temperature of the rechargeable battery detected can be the temperature of the rechargeable battery environment or the temperature of the surface of the rechargeable battery. The temperature detection unit is preferably installed on the upper part of the surface of the rechargeable battery, that is, the position below the battery cover above the plate, such as Lead-acid batteries.
