Electric Vehicle Battery Maintenance 6 Skills

Wednesday, February 24th, 2010

Right now, electric cars because of its advantages such as light pollution deeply consumers, while the mileage to measure the length of a consumer good or bad the quality of electric vehicles, one of the main criteria. It is worth mentioning that a large number of electric vehicles in the quality of complaints, accounting for over 95% of the battery problem, because the battery is to determine the length of electric vehicles an important factor in the exercise of mileage. Then the normal maintenance of electric vehicle batteries should pay attention to what the problem?

“Times can be battery Rehabilitation Center” maintenance of professional knowledge on the battery and gave specific description.

Technique, when a non-loss storage electric

When the battery in storage is prohibited in the state power loss. Loss refers to the battery power status is failure to make timely charge after use. Stored battery power status in the deficit, it is prone to sulfate, lead sulfate crystals attached to the pole plate, plug the electric ion channels, resulting in insufficient charging, the compaq Presario R3000 battery capacity decline. Idle state electricity loss the longer the more serious the damage to the battery. Therefore, the battery idle, we should add power once a month, so that can better maintain battery health.

2 regular inspection techniques

The use of process, if continued line of electric cars, a sudden drop in mileage in a short time more than ten kilometers, it is likely that at least one battery in the battery occurs off grid, plate softening, plate active material shedding phenomena such as short-circuit . At this point, the battery should be repaired in time to professional organizations to inspect, repair, or distribution group. This could be relatively extended battery life, maximize cost savings Inspiron 700m battery,Inspiron 710m battery.

Tips to avoid the three high-current discharge

Electric car start, manned, uphill, please help with the pedal as far as possible to avoid the momentary high-current discharge. High-current discharge easily lead to lead sulfate crystallization, to the detriment of the physical properties of the battery plates.

Charging time to master the right skills 4

The use of the process, should be based on the actual situation accurately charge time, refer to usual frequency of use and the mileage situation and pay attention to the capacity of the size of the battery manufacturers to provide instructions, as well as matching the performance of charger, the charge current to grasp the size of the charging parameters such as frequency of . General, batteries are charged at night, with an average charging time of 8 hours. If the shallow discharge (charge mileage is very short), the battery will soon be filled, to continue charging overcharge phenomenon occurs, leading to cell dehydration, fever, lower battery life. Therefore, the battery in order to discharge a depth of 60% -70% of the best to recharge a battery, the actual use can be converted into a riding mileage charge based on actual conditions necessary to avoid damaging charge.

5 tips to prevent exposure

Electric vehicles is prohibited under the sun exposure. Battery temperature is too high internal pressure makes the environment through increased cell pressure limiting valve was forced to automatically open a direct consequence of water loss is to increase the battery while the Inspiron E1405 battery cells will inevitably lead to excessive water loss decreased activity to accelerate the plate softening, charging shell body heat, since the shell drums, distortion and other fatal injuries.

6 tips to avoid the charging plug fever

Charger output plug loose contact surface oxidation phenomena such as charging plug will cause fever, fever for too long will lead to short-circuit charging plug, direct damage to chargers, lead to unnecessary losses. So, found out that the situation should be promptly removed oxides or replacement connector.

Economical and practical solution for backup battery monitoring

Wednesday, February 10th, 2010

Support the infrastructure of modern society must be based on a very high reliability of operation. Internet and telecommunications switching center server farms in order to ensure nearly 100% of the “trouble-free run-time” or system availability, they mostly rely on a very mature technology – lead-acid batteries, while the data storage center are used in high-tech. Typically, these key nodes, and many other important sectors are equipped with standby power, standby power supply is generally the first level inverter, inverter pairs of VRLA (VRLA) battery or a similar performance, sealed gel batteries assembled battery Section of power conversion.

The reason why traditional techniques are widely used, there are many reasons, especially lead-acid batteries affordable, but also with outstanding reliability. But while great but not perfect. VRLA battery life is limited (generally 12 years design life), often mission-critical systems using this battery as a backup power supply, but changed regularly. Failure may indeed occur. In a typical standby power systems, the role of the battery as its name – they always maintain a fully charged state of waiting for the main power failure. And the fully charged state of continuous small current through the “float” charge to maintain. If the float current is below a set limit, then the battery inside the gases produced by electrolysis will be re-chemical combination. In this case, a single battery float voltage is even slightly higher than the standard value of 2.27 V, may also damage the battery. Slightly over-voltage will cause precipitation of the electrolyte capacity of more than Recombination more gas, these gases are not handled through the overflow valve. If the battery temperature is too high, even if the charging voltage is appropriate, can lead to electrolyte loss.

Other failure modes include early sulfation, very bad columns and grid connection, grid connection plate and the bad, electrolyte stratification and grid accelerate corrosion. There is yet another, though a small but catastrophic failure modes – thermal runaway, which is peculiar to VRLA gel batteries, and a failure modes, can lead to burst into flames. The only way to prevent thermal runaway is to monitor the internal temperature of the battery.

Simply monitoring the battery voltage on the detection of lead-acid battery capacity decline in the role is very limited, it has been recognized throughout the industry. When the battery performance is declining, it is usually presented is that the nominal voltage, until the release of large currents can only apparent, but when its capacity has been severely reduced voltage drop prematurely. By measuring the proportion of electrolyte to determine the exact battery status, the method of the VRLA or sealed gel batteries does not apply; routine, the test battery used in the only way is to discharge the battery pack to a controlled state of the following, but this approach need to stop using the battery. In addition, the depth of discharge also reduces the life of lead-acid battery; in on a regular basis to conduct its backup battery discharge test, as well as its main power supply with high reliability of the system, most programs use this test to determine battery life.

Recently, continuous monitoring can be a non-intervention electronic method can detect a single cell near the failure state, this method can not only save costs, while maintaining overall system availability. The predecessor of such systems is usually measured cell or battery pack (battery industry term which means that within the shell in the same package multiple battery) voltage – despite its limitations is well known – with charge / discharge current and ambient temperature. Some systems attempt to measure or guess the battery internal resistance, its effectiveness varies.

LEM’s Sentinel system is dependent on the basic parameters of a simple analog measurements of change leading product has now grown to the first three generation of the Sentinel III. It is custom-designed single-chip SoC (System on Chip) IC on the integration of analog and digital technology. The device configured in a measured terminal voltage, the battery internal temperature and internal resistance of the module, can provide accurate measurement results for the cost again in most of the backup system configuration can afford within the budget of the system, it is the design of a key elements.
