（実施例１）
本実施例の電動アシスト自転車は、モータ、スマートロック、自転車本体及び電動アシスト自転車の電源管理システムを含み、電動アシスト自転車の電源管理システムはモータに動力を配置する。電動アシスト自転車の電源管理システムのＭＣＵはスマートロックと通信してスマートロックの信号に基づいて動力出力を起動する。スマートロックとしてはブルートゥース（登録商標）で通信するブルートゥースロックが用いられる。 (Example 1)
The electrically power assisted bicycle of this embodiment includes a motor, a smart lock, a bicycle body, and a power management system of the electrically power assisted bicycle, and the power management system of the electrically power assisted bicycle allocates power to the motor. The MCU of the power management system of the electrically power assisted bicycle communicates with the smart lock and activates the power output based on the signal of the smart lock. As a smart lock, Bluetooth lock that communicates with Bluetooth (registered trademark) is used.

図１に示すように、本実施例の電動アシスト自転車の電源管理システムは、モータコントローラー、駆動回路、電池、ＭＣＵ、充電電源モジュール、二段降圧回路を含む。本実施例において充電電源モジュールはソーラーパネルと充電モジュールを含み、風力エネルギー等の他の充電電源を採用してもよく、ここで、充電モジュールは主に太陽エネルギーを電気エネルギーに変換するインバーターである。 As shown in FIG. 1, the power management system of the electrically power assisted bicycle of this embodiment includes a motor controller, a drive circuit, a battery, an MCU, a charging power supply module, and a two-stage step-down circuit. In this embodiment, the charging power supply module includes a solar panel and a charging module, and other charging power sources such as wind energy may be adopted, where the charging module is mainly an inverter that converts solar energy into electrical energy. ..

モータコントローラーは電動アシスト自転車に設置されたモータを駆動するために用いられ、電気エネルギーをモータの出力する運動エネルギーに変換し、
駆動回路はモータコントローラーを駆動するために用いられる。具体的に言えば、駆動回路は、それぞれＭＣＵの信号により制御され、車載電池／移動式電池から電力を供給され、モータコントローラーを制御して電動アシスト自転車のモータを駆動させる２つの継電器である。 The motor controller is used to drive the motor installed in the electrically power assisted bicycle, and converts the electric energy into the kinetic energy output by the motor.
The drive circuit is used to drive the motor controller. Specifically, the drive circuits are two relays, each controlled by an MCU signal, supplied with power from an in-vehicle battery / mobile battery, and controlling a motor controller to drive a motor of an electrically power assisted bicycle.

電池は駆動回路とＭＣＵに電力を供給するために用いられ、車載電池と移動式電池を含む。車載電池は常に電力を供給する電池として、ユーザがいつでもソーラーパネルの変換した電気エネルギーを便利に蓄積でき、必要とされる時に、モータコントローラーに出力する。移動式電池は取り外し可能な電池としてユーザに保管され、ユーザにより充電され、モータコントローラーの主なエネルギー源となる。本実施例では動力を出力することのみに用いられる。移動式電池を優先的に使用するように２つの電池を設定し、移動式電池は大体使い切ることができる。電池の寿命を保護するために、本実施例では保護値を設定し、例えば電気量の５％にし、５％より低ければユーザに通知して充電させる。電動アシスト自転車を使用し続ける必要がある場合に、車載電池を用いて短時間の給電をすることができる。勿論、この保護値をより低く設定してもよく、更に０にしてもよい。さらに、車載電池の使用寿命を長くするために（車載電池の交換が容易ではなく、過度に使用すると、使用寿命が短くなってしまう）、車載電池に対しても保護値を設定し、例えば電気量の８０％にし、８０％より低ければ、車載電池の動力出力をオフする。 Batteries are used to power drive circuits and MCUs and include in-vehicle batteries and mobile batteries. The in-vehicle battery is a battery that constantly supplies electric power, and the user can conveniently store the converted electric energy of the solar panel at any time and output it to the motor controller when needed. Mobile batteries are stored by the user as removable batteries, charged by the user, and are the main source of energy for the motor controller. In this embodiment, it is used only to output power. The two batteries are set so that the mobile battery is used preferentially, and the mobile battery can be almost used up. In order to protect the life of the battery, in this embodiment, a protection value is set, for example, 5% of the amount of electricity, and if it is lower than 5%, the user is notified to charge the battery. When it is necessary to continue using the electrically power assisted bicycle, it is possible to supply power for a short time by using an in-vehicle battery. Of course, this protection value may be set lower, or even 0. Furthermore, in order to prolong the service life of the in-vehicle battery (it is not easy to replace the in-vehicle battery, and if it is used excessively, the service life will be shortened), a protection value is set for the in-vehicle battery, for example, electricity. The amount is 80%, and if it is lower than 80%, the power output of the in-vehicle battery is turned off.

ＭＣＵは車載電池と移動式電池に対する電圧サンプリングによって、駆動回路に電力を供給する車載電池／移動式電池を决定するために用いられる。本実施例では、ＭＣＵは型番５１８２２のブルートゥース制御チップであり、ブルートゥースロックとペアリングして、ロック解除コマンドに応じて電気を出力するために用いられる。
車載電池の残量が所定閾値以下になった時に、例えば１０％より低くなった時に、ＭＣＵは、車載電池の代わりに、移動式電源を制御して電動アシスト自転車に電力を供給させる。所定閾値としてはシステムの標準設定値を用いてもよく、ユーザが実際の要求に応じて自ら設定してもよいことを理解可能である。 The MCU is used to determine the in-vehicle battery / mobile battery that supplies power to the drive circuit by voltage sampling for the in-vehicle battery and the mobile battery. In this embodiment, the MCU is a Bluetooth control chip of model number 51822, which is used to pair with a Bluetooth lock and output electricity in response to an unlock command.
When the remaining amount of the in-vehicle battery becomes equal to or less than a predetermined threshold value, for example, when it becomes lower than 10%, the MCU controls a mobile power source to supply electric power to the electrically power assisted bicycle instead of the in-vehicle battery. It is understandable that the standard set value of the system may be used as the predetermined threshold value, and the user may set the predetermined threshold value by himself / herself according to the actual request.

好ましい実施例では、車載電池には２つのソーラーパネルと蓄電池が設置されている。２つのソーラーパネルがそれぞれ電動アシスト自転車のカゴの前側面と底面に敷設されているので、ソーラーパネルがより全面的に太陽光を吸収可能である。より多い太陽エネルギーを取得するために、車載電池はカゴの４側面と底面にそれぞれソーラーパネルを敷設してもよいことを理解可能である。蓄電池がカゴ底面の下方、即ちソーラーパネルに対向する他側に設置され、ソーラーパネルに電気的に接続される。そのため、ソーラーパネルは吸収した太陽エネルギーを電気エネルギーに変換して蓄電池に蓄積することができる。ソーラーパネル０が蓄電池に過度に充電することを回避するために、更にソーラーパネルと蓄電池の間に充放電制御素子を増設してもよいことを理解可能である。ソーラーパネルと充電モジュールは車載電池に充電するために用いられる。このソーラーパネルは大きい電圧及び電力で入力し、且つ定格電圧がシステム電池電圧より大きい。車載電池を保護するために、ここで、逆接続防止保護回路を設置してもよく、逆接続が起こった場合に、警告を出して通知する。実際の要求に応じてソーラーパネルの数量を選択し、設置位置としてはカゴの底部と側面に設置してもよいし、車両本体に設置してもよく、勿論、同時に複数設置してもよい。 In a preferred embodiment, the vehicle-mounted battery is equipped with two solar panels and a storage battery. Since the two solar panels are laid on the front side and bottom of the basket of the electrically power assisted bicycle, respectively, the solar panels can absorb sunlight more completely. It is understandable that in-vehicle batteries may have solar panels laid on each of the four sides and bottom of the car in order to obtain more solar energy. The storage battery is installed below the bottom of the basket, that is, on the other side facing the solar panel, and is electrically connected to the solar panel. Therefore, the solar panel can convert the absorbed solar energy into electric energy and store it in the storage battery. It is understandable that a charge / discharge control element may be further added between the solar panel and the storage battery in order to prevent the solar panel 0 from charging the storage battery excessively. Solar panels and charging modules are used to charge in-vehicle batteries. This solar panel inputs with a large voltage and power, and the rated voltage is higher than the system battery voltage. In order to protect the in-vehicle battery, a reverse connection prevention protection circuit may be installed here, and when a reverse connection occurs, a warning is issued to notify the user. The number of solar panels may be selected according to the actual requirements, and the solar panels may be installed on the bottom and side surfaces of the basket, may be installed on the vehicle body, and of course, a plurality of solar panels may be installed at the same time.

二段降圧回路の一段目の降圧回路は車載電池と移動式電池の出力電圧を１５Ｖに降圧して駆動回路に供給するために用いられ、二段目の降圧回路は一段目の降圧回路の出力電圧を３．３Ｖに降圧してＭＣＵに供給するために用いられる。２段の降圧回路は電圧を安定化させ降圧させるために、いずれもリニアレギュレータチップを用いてもよい。 The first-stage step-down circuit of the two-stage step-down circuit is used to step down the output voltage of the in-vehicle battery and the mobile battery to 15V and supply it to the drive circuit, and the second-stage step-down circuit is the output of the first-stage step-down circuit. It is used to step down the voltage to 3.3V and supply it to the MCU. A linear regulator chip may be used in each of the two-stage step-down circuits in order to stabilize and step down the voltage.

より安定的な駆動信号を取得するために、駆動回路の２つの継電器とＭＣＵの間にそれぞれ駆動増幅回路が設置される。駆動増幅回路は簡単であるが信頼性の高いトライオードを用いて増幅可能である。 In order to acquire a more stable drive signal, a drive amplifier circuit is installed between each of the two relays in the drive circuit and the MCU. The drive amplifier circuit is simple but can be amplified using a highly reliable triode.

図１と図２に示すように、電動アシスト自転車の電源管理方法は下記の重要点を含む。
１、ソーラーパネルに電気があり、且つソーラーパネルの充電モジュールを経由した出力電圧（図１の点Ａ）が車載電池の出力電圧（図１の点Ｂ）より高いことをソーラーパネルによる車載電池への充電の条件とする。
２、ＭＣＵは待機状態で１分毎に電動アシスト自転車のスマートロックのロック解除コマンドをスキャンし、ロック解除コマンドをスキャンした場合に、電動アシスト自転車の電源管理システムの電気エネルギーを電動アシスト自転車のモータに出力し、ＭＣＵによる電動アシスト自転車のスマートロックのロック解除コマンドの定期的スキャンに必要な電気量が車載電池により提供される。１分間のスキャン時間間隔が適切であり、時間が長過ぎればユーザ体験に影響を及ぼし、時間が短過ぎれば、電気消費量が多過ぎる。
３、車載電池と移動式電池に対して電圧保護値を設定し、ＭＣＵが車載電池と移動式電池に対して持続的にサンプリングして２つのリアルタイム電圧値を取得し、車載電池の電圧サンプリング値が車載電池保護値より低ければ、車載電池に接続された駆動回路の継電器をオフし、移動式電池の電圧サンプリング値が移動式電池保護値より低くなければ、移動式電池が全出力で出力する。 As shown in FIGS. 1 and 2, the power management method for the electrically power assisted bicycle includes the following important points.
1. To the in-vehicle battery by the solar panel that the solar panel has electricity and the output voltage via the charging module of the solar panel (point A in FIG. 1) is higher than the output voltage of the in-vehicle battery (point B in FIG. 1). It is a condition for charging.
2. The MCU scans the unlock command of the smart lock of the power-assisted bicycle every minute in the standby state, and when the unlock command is scanned, the electric energy of the power management system of the power-assisted bicycle is used as the motor of the power-assisted bicycle. The amount of electricity required for the periodic scan of the unlock command of the smart lock of the power-assisted bicycle by the MCU is provided by the in-vehicle battery. A one-minute scan time interval is appropriate, too long to affect the user experience, and too short to consume too much electricity.
3. Set the voltage protection value for the in-vehicle battery and the mobile battery, and the MCU continuously samples the in-vehicle battery and the mobile battery to acquire two real-time voltage values, and the voltage sampling value of the in-vehicle battery. If is lower than the in-vehicle battery protection value, the relay of the drive circuit connected to the in-vehicle battery is turned off, and if the voltage sampling value of the mobile battery is not lower than the mobile battery protection value, the mobile battery outputs at full output. ..
