Electric vehicles of all kinds must have battery stacks that provide the power required to drive the associated traction motor(s).
Well electric vehicles are the current invention and they will be on road very near future , and for them the Lilith-ion batteries are getting developed day by day to cope with them. Car Battery TesterBattery Tester Functions Battery internal resistance test: an important parameter to judge battery.
Directions: First choose model, then search by clicking anywhere on the car, choosing a "Tour" (red dots) or entering search terms. Active additive has been added in positive plate, so as to good consistency of the formated active material. The battery pack into the device to run automatically, auto fixed clamping welding fixture, sent after the completion of welding the welding station. By using the specially designed active material and strong grids, the EV series battery offers reliable performance in high load situations and can deliver more than 300 cycles at 100% DOD. Depending on whether it is an electric vehicle (EV), hybrid electric vehicle (HEV), or plug-in hybrid (PHEV), the required voltage may be in the range of about 200V to 400V. This new battery invention will give us a good back up and energy resource that will keep us secure on the go. To supply the required voltage and current, the overwhelming choice is now lithium-ion (Li-ion) rechargeable batteries that will require multiple cells to drive the traction motor(s). Also, Li-ion batteries offer more efficient storage capacity over multiple charge-discharge cycles, and suffer less charge leakage when not in use. And unlike NiMH batteries that have been used in some high-voltage applications, battery stacks using Li-ion technology can use fewer individual cells to produce hundreds of volts. At the higher operating voltages experienced in electric vehicles, this type of fault can be catastrophic. Although the quality of battery fabrication has improved, guarding against higher temperature and fault conditions in any automotive application remains crucial for reliable operation.
It is not unusual to have 100 cells connected in series to bring the total stack voltage up to the hundreds of volts.


Here, batteries in the Battery Management System power dc-ac inverters that drive its ac induction motors. Use of a high battery voltage reduces their average current, which cuts I2R power losses, allows smaller diameter cables, and reduces overall vehicle weight. ADI's system performs these functions while also allowing power system designers to replace costly discrete components, decrease power consumption and reduce system space. A safety monitor protects against discharging the battery too much, which can damage the batteries to the point where a replacement cost can be over $10,000. It is powered completely from the battery stack, providing either a shared or a separate alarm for any of three conditions: over-voltage, over-temperature or under-voltage. Other AD8280 features include: Extensive self-test enhances the designers ability to meet functional safety requirements, such as ISO26262 and IEC61508.
Large, continuous range-of-trip point settings allow the flexibility to work with any Li-ion battery chemistry. Daisy-chained implementations that minimize the need for isolators in a high-voltage cell stack. Compliant with AEC-Q100 and EMI (electromagnetic interference) standards, making it suitable for automotive applications.
It has multiplexed analog input and temperature measurement channels for up to six cells of battery management. If cell voltages exceed an upper or lower limit defined by the user, the AD7280 generates an interrupt output signal alert. It provides six pseudo-differential analog input channels to accommodate large common mode signals across the full VDD range. In addition, the AD7280 safety monitor can accommodate six external sensors for temperature measurement. The AD7280 includes on-chip registers that allow a sequence of channel measurements to be programmed to suit application requirements. Prior to charging, the battery stack all cells should be at the same voltage, which ensures that charged batteries will all end up with the same voltage.
It has balancing interface outputs that control external MOSFETs, and allow discharging of individual cells. Excellent dc and ac accuracy from -40°C to 125°C minimizes errors in the measurement loop without sacrificing cost and package size.
Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide better performance than optocouplers. These iCouplers eliminate the need for external drivers and other discrete components and consume one-tenth to one-sixth of the power consumed by optocouplers at comparable signal data rates.
The ADuM140x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and when power is not applied to one of its power supplies. This enables significant gains in signal conversion and computational precision, and applies advanced power control techniques that yield greater energy efficiency.
Designers are also enabled to utilize more advanced software tools and libraries for code generation, which helps shorten product development cycles and speed time to market without compromising on processor cost.
With optional integrated dual-SAR (successive approximation register) 12-bit ADCs for more accurate data conversion and 4MB of on-board executable flash memory, Blackfin BF50x processors minimize off-chip components that lower overall system costs.
An LTC6801 can monitor up to 12 series-connected battery cells for over-voltage and under-voltage conditions. You can daisy-chain multiple LTC6801s, providing a method to monitor each individual cell in very long battery strings. When connected in a daisy-chain, a single differential clock output confirms that all cells in the stack are within the defined operating range. This clock interface provides high noise immunity and ensures that fault conditions are not hidden by frozen bits or short circuit conditions. The result is a reliable and simple design that can serve as a complete monitoring or redundant circuit. It is a multi-cell monitor IC that provides accurate direct 12-bit digitizing of up to 12 series-connected battery potentials, cell balancing controls and even a pair of additional ADC inputs for temperature readings or other metrics. A Serial Peripheral Interface (SPI) digital connection to a local microprocessor comprises the means for command and data communication.


One version contains has an SPI port that can be daisy-chained without the need for isolation, further reducing cost and complexity in the module. This IC provides redundant cell monitoring to prevent Li-ion batteries from thermal runaway. Typical battery protection circuits incorporate three- and four-channel fault monitors with costly galvanic isolators between the monitors and an assortment of active and passive components.
This capability prevents cascading electrical failures and eliminates the expensive isolation components required by discrete solutions. In a typical hybrid car, Maxim's solution reduces the cost of the BMS by up to 80%, according to the company.
A 12-channel fault monitor employs a proprietary capacitor-isolated daisy-chain interface to minimize component count and cost. This unique architecture allows up to 31 devices to be connected in a series stack to monitor as many as 372 cells. Meanwhile, the capacitor-based interface provides extremely low-cost isolation from one bank of batteries to the next, eliminating cascading electrical failures. A unique built-in shutdown feature reduces consumption to an ultra-low 2µA leakage, allowing the pack to be stored for many years with very little battery drain The MAX11080 has 16 selectable overvoltage thresholds, as well as eight selectable under-voltage thresholds.
The device includes a programmable detection-delay feature that allows the user to filter out transient events in the battery pack to eliminate false overvoltage or under-voltage alarms. The alarm line operates using a 4kHz heartbeat signal, the absence of which indicates a valid overvoltage or under-voltage event.
These features are critical for discriminating between legitimate and false alarms, preventing the application from shutting down unnecessarily.
On power-up, the device automatically detects the presence of batteries and can be configured from two to 12 cells in any connection sequence or installation pattern. The device also self-tests the internal comparator circuitry to ensure proper functionality on power-up.
It can detect the open or short of any pin on the package and constantly monitors the pins for such a failure. At the higher operating voltages experienced in electric vehicles, an overvoltage can be catastrophic. Although these stacks are inherently dangerous, they must still communicate with the cell monitoring electronics, which are usually located within the battery enclosure. The number indicates the number of hours to completely discharge the battery at a constant current.
The useful capacity of a battery changes depending on the discharge rate, so battery capacities are stated with respect to a particular rate. It is defined as the current that the battery can deliver for 30 seconds and maintain a terminal voltage greater than or equal to 1.20 V per cell, at 0°F (-18°C), when the battery is new and fully charged. Starting batteries may also be rated for Cranking Amps, which is the same thing but at a temperature of 32°F (0°C). For example, if a hypothetical battery pack will propel your car for a maximum range of 100 miles, and you drive 50 miles between charges, (50% DOD) then you may get 600 trips before replacing the pack; but if you drove 80 miles between charges, you might only get 400 trips before the pack wears out.
Different types of lithium-ion batteries use different chemistries and have different characteristics.
Normally these batteries consist of several identical secondary cells in parallel to increase the discharge current capability. The battery has a nickel-hydroxide cathode, a cadmium anode, and aqueous potassium hydroxide electrolyte. NiMH is similar to nickel-cadmium but uses a metal hydride anode; a variety of metal alloys are used.
An SLI battery is designed to give a lot of current during starting, but then to be recharged immediately by the car's alternator.
