UM11817Introduction to 18-cell slider battery pack emulatorRev. 1 — 17 February 2023User manualIntroduction to 18-cell slider battery pack emulatorIntroduction to 18-cell slider battery pack emulator 1 IntroductionThe BATT-18EMULATOR board can emulate a multi-cell battery pack that can be easily hooked-up to the evaluation boards for MC33774 18-cell battery cell controllers (BCCs):•RD33774ADSTEVB - distributed board with single MC33774•RD33774CNT3EVB - centralized board with three MC33774The user can connect the BATT-18EMULATOR board for a quick evaluation of NXP BCC ICs, or to help the users in their software development. These boards basically provide a very intuitive way:•To change the voltage across any of the 18 cells of an emulated battery pack•To change the voltage across some analog inputs of the BCC IC that are typically used as temperature sensorsFigure 1. BATT-18EMULATOR2 Getting started2.1 Kit contents/packing listThe kit contents include:•BATT-18EMULATOR, 18-cell slider battery pack emulator•25 W AC-DC adapter with +5 VDC/5 A single output - DC plug type P1J (2.1 × 5.5 × 11 mm), tuning fork type, center positive•Adapter cable DC plug 2.1 × 5.5 × 11 mm to 2.5 × 5.5 × 9.5 mmIntroduction to 18-cell slider battery pack emulator 3 Getting to know the hardware3.1 Board features•18 slider potentiometers to adjust the cells voltage between 1.2 V and 3.3 V. The maximum total voltage has been limited to 60 V.•Three cells voltage can be inverted to apply voltages from −1.2 V to −3.3 V•Maximum current capability per channel: 200 mA•Three connectors for MC33774 evaluation boards connections•Temperature sensor output voltage can vary from 0 V to +4.95 V to simulate negative temperature coefficient (NTC) sensor3.2 Board functionsThe board has been designed and optimized for the operating conditions described in Table 1 and Table 2. Usage of the board beyond these conditions can lead to malfunction and damage.Table 1. Limiting valuesIn accordance with the Absolute Maximum Rating System (IEC 60134).[1]The maximum input supply current depends on the setup: number of boards connected, cells voltage, activated cell balancing channels; seeSection 3.3.3.[1]With jumpers setting, it is possible to get negative voltages from −3.3 V to −1.2 V for cells 13, 8 and 4; see Section 3.3.4.Introduction to 18-cell slider battery pack emulator 3.3 Board functional descriptionFigure 2. BATT-18EMULATOR board elements3.3.1 DescriptionEach cell emulation is made of a 5 V to 5 V unregulated isolated DC-DC converter and an adjustable regulator. The regulator output voltage is set thanks to a voltage slider. Minimum voltage is 1.2 V and maximum is set to 3.3 V.3.3.2 Connection and configurationThe emulator board requires a 5 V DC power supply with 5 A current capability. The power supply is connected to the board via J3 a Ø2.5 mm jack connector or using the 2 mm bananas J2(+) and J1(−). The center pinis connected to the positive voltage and the ring terminal to the ground. The input of the board is 5 A fuse protected. An LED allows the user to check that the board is powered up. If the voltage is present on the jack connector but the LED is off, then check the fuse F1.Up to three evaluation boards RD33774ADSTEVB or one RD33774CNT3EVB can be connected using connectors J4, J5, and J6 with no specific order.3.3.3 Current consumptionThe slider pack should be supplied with a +5 V AC-DC adapter or with a lab supply. The required supply current depends on several parameters described below.With no board connected, the default supply current on the 5 V primary is around 500 mA [19 × 28 mA (DC-DC typ supply current)].One RD33774ADSTEVB board, communicating, no balancing activated, consumes around 10.5 mA. Then the total supply current required on the 5 V primary is around 700 mA [500 mA + (19 × 10.5 mA)].If three boards are connected, then the supply current is 500 mA + (3 × 19 × 10.5 mA) = 1 A.If cell balancing is activated, the primary current depends on the cell voltage, the balancing resistance, and the number of balancing metal-oxide-semiconductor field-effect transistor (MOSFET) activated.Introduction to 18-cell slider battery pack emulator On RD33774ADSTEVB, the balancing resistance is 22 Ω per cell balancing channel. With V cell = 3.3 V, the peak balancing current is 150 mA peak, 75 mA average assuming a 50 % duty cycle. If N cell balancing MOSFETs are activated, then N × 75 mA are added to the primary current needed. If one board is connected and all18 cell balancing MOSFETs are activated, then the total current is 700 mA + 18 × 75 mA = 2 A. Each individual channel (200 mA of current capability) has to provide 10.5 mA + 75 mA averaged or 10.5 mA + 150 mA peak. Note: The current is limited to 180 mA per channel. If several boards are connected, it is recommended toavoid to activate same cell balancing channels at the same time on all the boards.3.3.4 Cell polarity selectionThree pairs of jumpers allow the polarity to be reversed for cell polarities for cell4 (C5M − C4M), cell8(C9M − C8M) and cell13 (C14M − C13M) therefore providing voltages between −1.2 V and −3.3 V; see Table 3.Note: Jumper selections should be done prior to supplying the BATT-18EMULATOR. Adjacent cell voltages are impacted when changing the polarities.3.3.5 External voltage injectionThe three jumpers can also be used as injection points to inject voltages above slider ranges: −1.2 V < V inj <+1.2 V or 3.3 V < V inj, typically to evaluate MC33774 cell terminal measurements at very low voltage (busbars) or a high-voltage cell.As example, to inject a voltage between C5M and C4M, remove jumper J8, keep jumper J7 1-2, and connect a floating supply between J8-2 and J7-1 or 2. Do not exceed maximum ratings and keep cell voltage in the range −5 V to +5 V.3.3.6 Temperature sensor simulationA separate slider allows the variation of the voltage across the temperature sensors.The temperature sensor output voltage can vary from 0 V to +4.95 V. It can mimic the temperaturevariation from −48 °C to +200 °C of a 10 kΩ NTC sensor. This output voltage is connected to four different general‑purpose input/output (GPIO) on the MC33774 (GPIO 1, 2, 7, 8) configured as ratiometric inputs with10 kΩ pull‑up resistors to VAUX (3.3 V typ.).3.4 MC33774 board connectionsThree 32 pins connectors (JAE Electronics MX34032NF2) J4, J5, J6 are connected in parallel as perthe following schematic Figure 3. Up to three boards (for example, RD33774ADSTEVB) or one boardRD33774CNT3EVB can be connected on any of these connectors.Introduction to 18-cell slider battery pack emulator Slider cell 0 is setting the voltage between C0M (cell0M) and C1M (cell0P), slider cell 1 is setting the voltage between C1M (cell1M) and C2M (cell1P), and so on, slider cell 17 is setting the voltage between C17M(cell17M) and C17P (cell17P).C17P-PWR and GND (pin 21) are used to supply the RD33774ADSTEVB and are separated from C17P andC0M respectively to avoid any voltage drop due to the current consumption of the evaluation boards.The slide temperature sensor is connected on pin 17 to pin 20 (NTC1, 2, 7 and 8 for RD33774DSTEVB).Figure 4. BATT-18EMULATOR connected to three RD33774DSTEVBIntroduction to 18-cell slider battery pack emulator 4 SchematicFigure 5. SchemaIntroduction to 18-cell slider battery pack emulator 5 Legal information5.1 DefinitionsDraft — A draft status on a document indicates that the content is still under internal review and subject to formal approval, which may resultin modifications or additions.

恩智浦FlexRay产品系列恩智浦半导体汽车电子事业部 Rob Hoeben，FlexRay市场营销经理FlexRay的发展历史FlexRay网络产品诞生于20世纪90年代末，当时一些汽车制造商意识到现有网络系统，例如CAN，无法满足未来车载网络（IVN）的需求。

这些汽车制造商没有开发自己的解决方案，而是决定组成一个协会，推动FlexRay通信系统成为汽车应用领域高速通信网络的行业标准。

基于当时在CAN和LIN收发器领域的主导作用，恩智浦半导体（NXP Semiconductors，原飞利浦半导体）受邀成为FlexRay协会的核心合作伙伴之一，负责引领行业开发网络物理层。

制定新的FlexRay标准花费了数年时间，这导致多种过渡版FlexRay技术标准应运而生。

恩智浦担任物理层工作小组的领导工作，并作为协会指导委员会的成员监测协会的工作进展。

为让协会的其它成员能对FlexRay的应用进行系统研究，恩智浦开发了第一个硬件解决方案。

这款产品称为恩智浦FlexRay TJA1080收发器。

2006年底，恩智浦实现重要的里程碑，第一款采用FlexRay网络的车型投入量产:宝马X5，其主动式阻尼控制系统采用恩智浦的TJA1080收发器。

因此，FlexRay不再只处于开发阶段，同样也已进入量产阶段，并获得实际应用。

TJA1080 – FlexRay的推动者作为世界上第一款采用FlexRay电气物理层的芯片，恩智浦的TJA 1080证明了FlexRay的强大性能与灵活便捷。

这种关键设备可提供广泛的功能组合、卓越的EMC性能以及高效的ESD 保护，有助于推动全新的先进通信系统进入目前和未来的车款。

TJA1080的主要功能∙FlexRay网络中的数据传输速度高达10Mbit/s∙支持FlexRay节点和有源星型结构功能∙ECU低功耗管理∙本地和远程唤醒功能∙数据帧唤醒∙通过两个专用控制输入实现模式控制∙带有VIO输入的自适应I/O∙兼容42V∙温度范围：- 40°C至+ 150°C∙± 8kV HBM ESD保护∙误差诊断和状态向量读数TJA1080投入量产以来，恩智浦从市场反馈和自身量产经验中获益良多。
