1, the discharge fever
Discharge Causes of fever are: discharge too quickly, it may be the battery capacity is low, the time of discharge current over 0.5c. Inspiron 1720 battery Inspiron 1721 battery
1) If the rated motor voltage is low, a smaller battery capacity, operating current is too large, the tension will be considerably reduced, the ability to quickly consumed the most negative on the battery.
2) The battery is only capable of maintaining the speed of electrochemical reaction of trafficking often do the full cycle of charging and discharging will not neglect super long. Wind faced uphill, great power, which requires a strong reaction to the plates of the battery, heat reservoir of top battery, damage the battery life shortened.
3) Ideally, the rate of reaction is the electrochemical battery provides enough power fully. The casing of the battery is not unusual heat, indicating the battery capacity is sufficient. MacBook Pro 15 inch battery A1078
2, load fever
The process of fever, the reasons for possible failure: one, their own problems, battery, battery aging, resistance becomes greater, the dry electrolyte, internal short circuits caused heat. With the increase in the number of batteries, which discharge and charge the battery in the progressive loss of water molecules, that is, we speak the gassing of the battery, water loss, causing the battery in the reaction electrochemical in heat, another is a solution of the battery in the process of charge-discharge formation of the crystallization of sulfuric acid, precipitation viscous in the stereotype, which leads to the battery and increases the thermal resistance, these two types of problems can be done by adding water to sulfur and other technical means to most to be treated. If the battery is due to sprint off the battery cell lead to fever, it would be better to replace with new batteries. Sony VGP-BPS2B Sony VGP-BPS2C
2) The problem of the shipper, in general, there is no charger function pulse, and no elimination of negative pulse-polarization, shippers can not normally be the last part of the constant pressure load, while causing the battery voltage exceeds the permissible value, leading to a large number of gas analysis of the battery, dehydration and fever. Ordinary chargers on the market today, but Yimei constant power load or the internal resistance of the battery and so detection may not be timely detected, and can not be a burden in the adjustment or load can not provide the best programs, these are the loading process of causing the battery to heat reasons. For the normal charger, can be artificially controlled temperature (which is an electric car factory given program). Method is: the beginning of the measurement increases, timely disconnect the power to stop the load, temperature and polarization which is its own end, but the reduction and elimination of polarization will take time. When the temperature is reduced, and then continued to charge after stop filling, and so on until full. But it’s a bit too disturbed a little, how a product regular charger battery, charging time, even for a small 12AH rechargeable batteries also need 8 hours or more, users of electric vehicles may not be sufficient electricity consumption for 8 hours to measure periodically the temperature of the battery, unplug the power supply connected to the power of these movements! Therefore, this method is not desirable. Tecra A6 battery Tecra A7 battery
Thus, in order to fundamentally solve the problems caused by the battery charger because of fever, then we need the correct selection of chargers, battery chargers process is a process of electrochemical reaction in this process, if the battery it appears the situation is within the normal range of trace fever fever, should the heating anomalies in the battery case of good performance belong to the charger reasons.
Choosing Chargers do? Firstly, the charger for charging pulse, the pulse charging method of charging as follows: cost – stop – rechargeable – stop … … This is so that the battery capacity to a greater acceptance of the electrochemical reaction, while stopping the filling process it beneficial for battery exaggerated calm.
Secondly, the selection of the best chargers have the function of negative pulse can recharge the GD761 KD476 battery at the same time playing a certain amount of maintenance to the end, both positive and negative charger or regular charger pulse, they pay problem of process control is re – in a heavy feeder the same positive and negative pulses, if the load control inaccurate, it would also damage the battery chargers for being on the market are essentially continuous exercise of power, constant voltage, three-charger, pulse charger, the recently introduced a new concept of technology load control, this charger is based on many aspects of technology, we call the control technology is not too fuzzy, ranging from general discussion, it was here, we’ll use less formal language to introduce, to bring before that, let us a look at three-charger, the so-called triple? Is a constant current, constant voltage, constant power charge mode, it recharges the battery when the corresponding functions have a certain degree of rationality, but it ultimately can not control the loading process of drums in heat in the production of this phenomenon, because it’s loading process is in three stages in a conventional manner, knows the performance of the battery right on the market vary, a general model of charging a group of performance parameters perfectly match the language of the drums, the same as the load is the best way, but for another group the difference in performance of battery, then the effect will be totally different, the battery charge a slight fever, rechargeable batteries or rechargeable battery exploded when the battery is possible! So how can you match each set of rechargeable batteries are the best model? As the microcontroller used in a battery charger, the problem will be solved gradually, at any time in the sense resistor voltage PA3399U-2BAS PA3399U-1BRS battery, and so on, timely select the corresponding tax, non-stationary process loading, which is our praise for this new The basic principle of the control technology of charge!
